feat: gstack browser sidebar = interactive Claude Code REPL with live tab awareness (v1.14.0.0) (#1216)
* build: vendor xterm@5 for the Terminal sidebar tab
Adds xterm@5 + xterm-addon-fit as devDependencies and a `vendor:xterm`
build step that copies the assets into `extension/lib/` at build time.
The vendored files are .gitignored so the npm version stays the source
of truth. xterm@5 is eval-free, so no MV3 CSP changes needed.
No runtime callers yet — this just stages the assets.
* feat(server): add pty-session-cookie module for the Terminal tab
Mirrors `sse-session-cookie.ts` exactly. Mints short-lived 30-min HttpOnly
cookies for authenticating the Terminal-tab WebSocket upgrade against
the terminal-agent. Same TTL, same opportunistic-pruning shape, same
"scoped tokens never valid as root" invariant. Two registries instead of
one because the cookie names are different (`gstack_sse` vs `gstack_pty`)
and the token spaces must not overlap.
No callers yet — wired up in the next commit.
* feat(server): add terminal-agent.ts (PTY for the Terminal sidebar tab)
Translates phoenix gbrowser's Go PTY (cmd/gbd/terminal.go) into a Bun
non-compiled process. Lives separately from `sidebar-agent.ts` so a
WS-framing or PTY-cleanup bug can't take down the chat path (codex
outside-voice review caught the coupling risk).
Architecture:
- Bun.serve on 127.0.0.1:0 (never tunneled).
- POST /internal/grant accepts cookie tokens from the parent server over
loopback, authenticated with a per-boot internal token.
- GET /ws upgrades require BOTH (a) Origin: chrome-extension://<id> and
(b) the gstack_pty cookie minted by /pty-session. Either gate alone is
insufficient (CSWSH defense + auth defense).
- Lazy spawn: claude PTY is not started until the WS receives its first
data frame. Idle sidebar opens cost nothing.
- Bun PTY API: `terminal: { rows, cols, data(t, chunk) }` — verified at
impl time on Bun 1.3.10. proc.terminal.write() for input,
proc.terminal.resize() for resize, proc.kill() + 3s SIGKILL fallback
on close.
- process.on('uncaughtException'|'unhandledRejection') handlers so a
framing bug logs but doesn't kill the listener loop.
Test-only `BROWSE_TERMINAL_BINARY` env override lets the integration
tests spawn /bin/bash instead of requiring claude on every CI runner.
Not yet spawned by anything — wired in the next commit.
* feat(server): wire /pty-session route + spawn terminal-agent
Server-side glue connecting the Terminal sidebar tab to the new
terminal-agent process.
server.ts:
- New POST /pty-session route. Validates AUTH_TOKEN, mints a gstack_pty
HttpOnly cookie via pty-session-cookie.ts, posts the cookie value to
the agent's loopback /internal/grant. Returns the terminalPort + Set-Cookie
to the extension.
- /health response gains `terminalPort` (just the port number — never a
shell token). Tokens flow via the cookie path, never /health, because
/health already surfaces AUTH_TOKEN to localhost callers in headed mode
(that's a separate v1.1+ TODO).
- /pty-session and /terminal/* are deliberately NOT added to TUNNEL_PATHS,
so the dual-listener tunnel surface 404s by default-deny.
- Shutdown path now also pkills terminal-agent and unlinks its state files
(terminal-port + terminal-internal-token) so a reconnect doesn't try to
hit a dead port.
cli.ts:
- After spawning sidebar-agent.ts, also spawn terminal-agent.ts. Same
pattern: pkill old instances, Bun.spawn(['bun', 'run', script]) with
BROWSE_STATE_FILE + BROWSE_SERVER_PORT env. Non-fatal if the spawn
fails — chat still works without the terminal agent.
* feat(extension): Terminal as default sidebar tab
Adds a primary tab bar (Terminal | Chat) above the existing tab-content
panes. Terminal is the default-active tab; clicking Chat returns to the
existing claude -p one-shot flow which is preserved verbatim.
manifest.json: adds ws://127.0.0.1:*/ to host_permissions so MV3 doesn't
block the WebSocket upgrade.
sidepanel.html: new primary-tabs nav, new #tab-terminal pane with a
"Press any key to start Claude Code" bootstrap card, claude-not-found
install card, xterm mount point, and "session ended" restart UI. Loads
xterm.js + xterm-addon-fit + sidepanel-terminal.js. tab-chat is no
longer the .active default.
sidepanel.js: new activePrimaryPaneId() helper that reads which primary
tab is selected. Debug-close paths now route back to whichever primary
pane is active (was hardcoded to tab-chat). Primary-tab click handler
toggles .active classes and aria-selected. window.gstackServerPort and
window.gstackAuthToken exposed so sidepanel-terminal.js can build the
/pty-session POST and the WS URL.
sidepanel-terminal.js (new): xterm.js lifecycle. Lazy-spawn — first
keystroke fires POST /pty-session, then opens
ws://127.0.0.1:<terminalPort>/ws. Origin + cookie are set automatically
by the browser. Resize observer sends {type:"resize"} text frames.
ResizeObserver, tab-switch hooks, restart button, install-card retry.
On WS close shows "Session ended, click to restart" — no auto-reconnect
(codex outside-voice flagged that as session-burning).
sidepanel.css: primary-tabs bar + Terminal pane styling (full-height
xterm container, install card, ended state).
* test: terminal-agent + cookie module + sidebar default-tab regression
Three new test files:
terminal-agent.test.ts (16 tests): pty-session-cookie mint/validate/
revoke, Set-Cookie shape (HttpOnly + SameSite=Strict + Path=/, NO Secure
since 127.0.0.1 over HTTP), source-level guards that /pty-session and
/terminal/* are NOT in TUNNEL_PATHS, /health does NOT surface ptyToken
or gstack_pty, terminal-agent binds 127.0.0.1, /ws upgrade enforces
chrome-extension:// Origin AND gstack_pty cookie, lazy-spawn invariant
(spawnClaude is called from message handler, not upgrade), uncaughtException/
unhandledRejection handlers exist, SIGINT-then-SIGKILL cleanup.
terminal-agent-integration.test.ts (7 tests): spawns the agent as a real
subprocess in a tmp state dir. Verifies /internal/grant accepts/rejects
the loopback token, /ws gates (no Origin → 403, bad Origin → 403, no
cookie → 401), real WebSocket round-trip with /bin/bash via the
BROWSE_TERMINAL_BINARY override (write 'echo hello-pty-world\n', read it
back), and resize message acceptance.
sidebar-tabs.test.ts (13 tests): structural regression suite locking the
load-bearing invariants of the default-tab change — Terminal is .active,
Chat is not, xterm assets are loaded, debug-close path no longer hardcodes
tab-chat (uses activePrimaryPaneId), primary-tab click handler exists,
chat surface is not accidentally deleted, terminal JS does NOT auto-
reconnect on close, manifest declares ws:// + http:// localhost host
permissions, no unsafe-eval.
Plan called for Playwright + extension regression; the codebase doesn't
ship Playwright extension launcher infra, so we follow the existing
extension-test pattern (source-level structural assertions). Same
load-bearing intent — locks the invariants before they regress.
* docs: Terminal flow + threat model + v1.1 follow-ups
SIDEBAR_MESSAGE_FLOW.md: new "Terminal flow" section. Documents the WS
upgrade path (/pty-session cookie mint → /ws Origin + cookie gate →
lazy claude spawn), the dual-token model (AUTH_TOKEN for /pty-session,
gstack_pty cookie for /ws, INTERNAL_TOKEN for server↔agent loopback),
and the threat-model boundary — the Terminal tab bypasses the entire
prompt-injection security stack on purpose; user keystrokes are the
trust source. That trust assumption is load-bearing on three transport
guarantees: local-only listener, Origin gate, cookie auth. Drop any
one of those three and the tab becomes unsafe.
CLAUDE.md: extends the "Sidebar architecture" note to include
terminal-agent.ts in the read-this-first list. Adds a "Terminal tab is
its own process" note so a future contributor doesn't bolt PTY logic
onto sidebar-agent.ts.
TODOS.md: three new follow-ups under a new "Sidebar Terminal" section:
- v1.1: PTY session survives sidebar reload (Issue 1C deferred).
- v1.1+: audit /health AUTH_TOKEN distribution (codex finding #2 —
a pre-existing soft leak that cc-pty-import sidesteps but doesn't
fix).
- v1.1+: apply terminal-agent's process.on exception handlers to
sidebar-agent.ts (codex finding #4 — chat path has no fatal
handlers).
* feat(extension): Terminal-only sidebar — auth fix, UX polish, chat rip
The chat queue path is gone. The Chrome side panel is now just an
interactive claude PTY in xterm.js. Activity / Refs / Inspector still
exist behind the `debug` toggle in the footer.
Three threads of change, all from dogfood iteration on top of
cc-pty-import:
1. fix(server): cross-port WS auth via Sec-WebSocket-Protocol
- Browsers can't set Authorization on a WebSocket upgrade. We had
been minting an HttpOnly gstack_pty cookie via /pty-session, but
SameSite=Strict cookies don't survive the cross-port jump from
server.ts:34567 to the agent's random port from a chrome-extension
origin. The WS opened then immediately closed → "Session ended."
- /pty-session now also returns ptySessionToken in the JSON body.
- Extension calls `new WebSocket(url, [`gstack-pty.<token>`])`.
Browser sends Sec-WebSocket-Protocol on the upgrade.
- Agent reads the protocol header, validates against validTokens,
and MUST echo the protocol back (Chromium closes the connection
immediately if a server doesn't pick one of the offered protocols).
- Cookie path is kept as a fallback for non-browser callers (curl,
integration tests).
- New integration test exercises the full protocol-auth round-trip
via raw fetch+Upgrade so a future regression of this exact class
fails in CI.
2. fix(extension): UX polish on the Terminal pane
- Eager auto-connect when the sidebar opens — no "Press any key to
start" friction every reload.
- Always-visible ↻ Restart button in the terminal toolbar (not
gated on the ENDED state) so the user can force a fresh claude
mid-session.
- MutationObserver on #tab-terminal's class attribute drives a
fitAddon.fit() + term.refresh() when the pane becomes visible
again — xterm doesn't auto-redraw after display:none → display:flex.
3. feat(extension): rip the chat tab + sidebar-agent.ts
- Sidebar is Terminal-only. No more Terminal | Chat primary nav.
- sidebar-agent.ts deleted. /sidebar-command, /sidebar-chat,
/sidebar-agent/event, /sidebar-tabs* and friends all deleted.
- The pickSidebarModel router (sonnet vs opus) is gone — the live
PTY uses whatever model the user's `claude` CLI is configured with.
- Quick-actions (🧹 Cleanup / 📸 Screenshot / 🍪 Cookies) survive
in the Terminal toolbar. Cleanup now injects its prompt into the
live PTY via window.gstackInjectToTerminal — no more
/sidebar-command POST. The Inspector "Send to Code" action uses
the same injection path.
- clear-chat button removed from the footer.
- sidepanel.js shed ~900 lines of chat polling, optimistic UI,
stop-agent, etc.
Net diff: -3.4k lines across 16 files. CLAUDE.md, TODOS.md, and
docs/designs/SIDEBAR_MESSAGE_FLOW.md rewritten to match. The sidebar
regression test (browse/test/sidebar-tabs.test.ts) is rewritten as 27
structural assertions locking the new layout — Terminal sole pane,
no chat input, quick-actions in toolbar, eager-connect, MutationObserver
repaint, restart helper.
* feat: live tab awareness for the Terminal pane
claude in the PTY now has continuous tab-aware context. Three pieces:
1. Live state files. background.js listens to chrome.tabs.onActivated /
onCreated / onRemoved / onUpdated (throttled to URL/title/status==
complete so loading spinners don't spam) and pushes a snapshot. The
sidepanel relays it as a custom event; sidepanel-terminal.js sends
{type:"tabState"} text frames over the live PTY WebSocket.
terminal-agent.ts writes:
<stateDir>/tabs.json all open tabs (id, url, title, active,
pinned, audible, windowId)
<stateDir>/active-tab.json current active tab (skips chrome:// and
chrome-extension:// internal pages)
Atomic write via tmp + rename so claude never reads a half-written
document. A fresh snapshot is pushed on WS open so the files exist by
the time claude finishes booting.
2. New $B tab-each <command> [args...] meta-command. Fans out a single
command across every open tab, returns
{command, args, total, results: [{tabId, url, title, status, output}]}.
Skips chrome:// pages; restores the originally active tab in a finally
block (so a mid-batch error doesn't leave the user looking at a
different tab); uses bringToFront: false so the OS window doesn't
jump on every fanout. Scope-checks the inner command BEFORE the loop.
3. --append-system-prompt hint at spawn time. Claude is told about both
the state files and the $B tab-each command up front, so it doesn't
have to discover the surface by trial. Passed via the --append-system-
prompt CLI flag, NOT as a leading PTY write — the hint stays out of
the visible transcript.
Tests:
- browse/test/tab-each.test.ts (new) — registration + source-level
invariants (scope check before loop, finally-restore, bringToFront:false,
chrome:// skip) + behavior tests with a mock BrowserManager that verify
iteration order, JSON shape, error handling, and active-tab restore.
- browse/test/terminal-agent.test.ts — three new assertions for
tabState handler shape, atomic-write pattern, and the
--append-system-prompt wiring at spawn.
Verified live: opened 5 tabs, ran $B tab-each url against the live
server, got per-tab JSON results back, original active tab restored
without OS focus stealing.
* chore: drop sidebar-agent test refs after chat rip
Five test files / describe blocks targeted the deleted chat path:
- browse/test/security-e2e-fullstack.test.ts (full-stack chat-pipeline E2E
with mock claude — whole file gone)
- browse/test/security-review-fullstack.test.ts (review-flow E2E with real
classifier — whole file gone)
- browse/test/security-review-sidepanel-e2e.test.ts (Playwright E2E for
the security event banner that was ripped from sidepanel.html)
- browse/test/security-audit-r2.test.ts (5 describe blocks: agent queue
permissions, isValidQueueEntry stateFile traversal, loadSession session-ID
validation, switchChatTab DocumentFragment, pollChat reentrancy guard,
/sidebar-tabs URL sanitization, sidebar-agent SIGTERM→SIGKILL escalation,
AGENT_SRC top-level read converted to graceful fallback)
- browse/test/security-adversarial-fixes.test.ts (canary stream-chunk split
detection on detectCanaryLeak; one tool-output test on sidebar-agent)
- test/skill-validation.test.ts (sidebar agent #584 describe block)
These all assumed sidebar-agent.ts existed and tested chat-queue plumbing,
chat-tab DOM round-trip, chat-polling reentrancy, or per-message classifier
canary detection. With the live PTY there is no chat queue, no chat tab,
no LLM stream to canary-scan, and no per-message subprocess. The Terminal
pane's invariants are covered by the new browse/test/sidebar-tabs.test.ts
(27 structural assertions), browse/test/terminal-agent.test.ts, and
browse/test/terminal-agent-integration.test.ts.
bun test → exit 0, 0 failures.
* chore: bump version and changelog (v1.14.0.0)
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* fix(extension): xterm fills the full Terminal panel height
The Terminal pane only rendered into the top portion of the panel — most
of the panel below the prompt was an empty black gap. Three layered
issues, all about xterm.js measuring dimensions during a layout state
that wasn't ready yet:
1. order-of-operations in connect(): ensureXterm() ran BEFORE
setState(LIVE), so term.open() measured els.mount while it was still
display:none. xterm caches a 0-size viewport synchronously inside
open() and never auto-recovers when the container goes visible.
Flipped: setState(LIVE) → ensureXterm.
2. first fit() ran synchronously before the browser had applied the
.active class transition. Wrapped in requestAnimationFrame so layout
has settled before fit() reads clientHeight.
3. CSS flex-overflow trap: .terminal-mount has flex:1 inside the
flex-column #tab-terminal, but .tab-content's `overflow-y: auto` and
the lack of `min-height: 0` on .terminal-mount meant the item
couldn't shrink below content size. flex:1 then refused to expand
into available space and xterm rendered into whatever its initial
2x2 measurement happened to be.
Fixes:
- extension/sidepanel-terminal.js: reorder + RAF fit
- extension/sidepanel.css: .terminal-mount gets `flex: 1 1 0` +
`min-height: 0` + `position: relative`. #tab-terminal overrides
.tab-content's `overflow-y: auto` to `overflow: hidden` (xterm has
its own viewport scroll; the parent shouldn't compete) and explicitly
re-declares `display: flex; flex-direction: column` for #tab-terminal.active.
bun test browse/test/sidebar-tabs.test.ts → 27/27 pass.
Manually verified: side panel opens → Terminal fills full panel height,
xterm scrollback works, debug-tab toggle still repaints correctly.

feat(security): ML prompt injection defense for sidebar (v1.4.0.0) (#1089)
* chore(deps): add @huggingface/transformers for prompt injection classifier
Dependency needed for the ML prompt injection defense layer coming in the
follow-up commits. @huggingface/transformers will host the TestSavantAI
BERT-small classifier that scans tool outputs for indirect prompt injection.
Note: this dep only runs in non-compiled bun contexts (sidebar-agent.ts).
The compiled browse binary cannot load it because transformers.js v4 requires
onnxruntime-node (native module, fails to dlopen from bun compile's temp
extract dir). See docs/designs/ML_PROMPT_INJECTION_KILLER.md for the full
architectural decision.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(security): add security.ts foundation for prompt injection defense
Establishes the module structure for the L5 canary and L6 verdict aggregation
layers. Pure-string operations only — safe to import from the compiled browse
binary.
Includes:
* THRESHOLDS constants (BLOCK 0.85 / WARN 0.60 / LOG_ONLY 0.40), calibrated
against BrowseSafe-Bench smoke + developer content benign corpus.
* combineVerdict() implementing the ensemble rule: BLOCK only when the ML
content classifier AND the transcript classifier both score >= WARN.
Single-layer high confidence degrades to WARN to prevent any one
classifier's false-positives from killing sessions (Stack Overflow
instruction-writing-style FPs at 0.99 on TestSavantAI alone).
* generateCanary / injectCanary / checkCanaryInStructure — session-scoped
secret token, recursively scans tool arguments, URLs, file writes, and
nested objects per the plan's all-channel coverage decision.
* logAttempt with 10MB rotation (keeps 5 generations). Salted SHA-256 hash,
per-device salt at ~/.gstack/security/device-salt (0600).
* Cross-process session state at ~/.gstack/security/session-state.json
(atomic temp+rename). Required because server.ts (compiled) and
sidebar-agent.ts (non-compiled) are separate processes.
* getStatus() for shield icon rendering via /health.
ML classifier code will live in a separate module (security-classifier.ts)
loaded only by sidebar-agent.ts — compiled browse binary cannot load the
native ONNX runtime.
Plan: ~/.gstack/projects/garrytan-gstack/ceo-plans/2026-04-19-prompt-injection-guard.md
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(security): wire canary injection into sidebar spawnClaude
Every sidebar message now gets a fresh CANARY-XXXXXXXXXXXX token embedded
in the system prompt with an instruction for Claude to never output it on
any channel. The token flows through the queue entry so sidebar-agent.ts
can check every outbound operation for leaks.
If Claude echoes the canary into any outbound channel (text stream, tool
arguments, URLs, file write paths), the sidebar-agent terminates the
session and the user sees the approved canary leak banner.
This operation is pure string manipulation — safe in the compiled browse
binary. The actual output-stream check (which also has to be safe in
compiled contexts) lives in sidebar-agent.ts (next commit).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* test(security): make sidebar-agent destructure check regex-tolerant
The test asserted the exact string `const { prompt, args, stateFile, cwd, tabId } = queueEntry`
which breaks whenever security or other extensions add fields (canary, pageUrl,
etc.). Switch to a regex that requires the core fields in order but tolerates
additional fields in between. Preserves the test's intent (args come from the
queue entry, not rebuilt) while allowing the destructure to grow.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(security): canary leak check across all outbound channels
The sidebar-agent now scans every Claude stream event for the session's
canary token before relaying any data to the sidepanel. Channels covered
(per CEO review cross-model tension #2):
* Assistant text blocks
* Assistant text_delta streaming
* tool_use arguments (recursively, via checkCanaryInStructure — catches
URLs, commands, file paths nested at any depth)
* tool_use content_block_start
* tool_input_delta partial JSON
* Final result payload
If the canary leaks on any channel, onCanaryLeaked() fires once per session:
1. logAttempt() writes the event to ~/.gstack/security/attempts.jsonl
with the canary's salted hash (never the payload content).
2. sends a `security_event` to the sidepanel so it can render the approved
canary-leak banner (variant A mockup — ceo-plan 2026-04-19).
3. sends an `agent_error` for backward-compat with existing error surfaces.
4. SIGTERM's the claude subprocess (SIGKILL after 2s if still alive).
The leaked content itself is never relayed to the sidepanel — the event is
dropped at the boundary. Canary detection is pure-string substring match,
so this all runs safely in the sidebar-agent (non-compiled bun) context.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(security): add security-classifier.ts with TestSavantAI + Haiku
This module holds the ML classifier code that the compiled browse binary
cannot link (onnxruntime-node native dylib doesn't load from Bun compile's
temp extract dir — see CEO plan §"Pre-Impl Gate 1 Outcome"). It's imported
ONLY by sidebar-agent.ts, which runs as a non-compiled bun script.
Two layers:
L4 testsavant_content — TestSavantAI BERT-small ONNX classifier. First call
triggers a one-time 112MB model download to ~/.gstack/models/testsavant-small/
(files staged into the onnx/ layout transformers.js v4 expects). Classifies
page snapshots and tool outputs for indirect prompt injection + jailbreak
attempts. On benign-corpus dry-run: Wikipedia/HN/Reddit/tech-blog all score
SAFE 0.98+, attack text scores INJECTION 0.99+, Stack Overflow
instruction-writing now scores SAFE 0.98 on the shorter form (was 0.99
INJECTION on the longer form — instruction-density threshold). Ensemble
combiner downgrades single-layer high to WARN to cover this case.
L4b transcript_classifier — Claude Haiku reasoning-blind pre-tool-call scan.
Sees only {user_message, last 3 tool_calls}, never Claude's chain-of-thought
or tool results (those are how self-persuasion attacks leak). 2000ms hard
timeout. Fail-open on any subprocess failure so sidebar stays functional.
Gated by shouldRunTranscriptCheck() — only runs when another layer already
fired at >= LOG_ONLY, saving ~70% of Haiku spend.
Both layers degrade gracefully: load/spawn failures set status to 'degraded'
and return confidence=0. Shield icon reflects this via getClassifierStatus()
which security.ts's getStatus() composes.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(security): wire TestSavantAI + ensemble into sidebar-agent pre-spawn scan
The sidebar-agent now runs a ML security check on the user message BEFORE
spawning claude. If the content classifier and (gated) transcript classifier
ensemble returns BLOCK, the session is refused with a security_event +
agent_error — the sidepanel renders the approved banner.
Two pieces:
1. On agent startup, loadTestsavant() warms the classifier in the background.
First run triggers a 112MB model download from HuggingFace (~30s on
average broadband). Non-blocking — sidebar stays functional during
cold-start, shield just reports 'off' until warmed.
2. preSpawnSecurityCheck() runs the ensemble against the user message:
- L4 (testsavant_content) always runs
- L4b (transcript_classifier via Haiku) runs only if L4 flagged at
>= LOG_ONLY — plan §E1 gating optimization, saves ~70% of Haiku spend
combineVerdict() applies the BLOCK-requires-both-layers rule, which
downgrades any single-layer high confidence to WARN. Stack Overflow-style
instruction-heavy writing false-positives on TestSavantAI alone are
caught by this degrade — Haiku corrects them when called.
Fail-open everywhere: any subprocess/load/inference error returns confidence=0
so the sidebar keeps working on architectural controls alone. Shield icon
reflects degraded state via getClassifierStatus().
BLOCK path emits both:
- security_event {verdict, reason, layer, confidence, domain} (for the
approved canary-leak banner UX mockup — variant A)
- agent_error "Session blocked — prompt injection detected..."
(backward-compat with existing error surface)
Regression test suite still passes (12/12 sidebar-security tests).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* test(security): add security.ts unit tests (25 tests, 62 assertions)
Covers the pure-string operations that must behave deterministically in both
compiled and source-mode bun contexts:
* THRESHOLDS ordering invariant (BLOCK > WARN > LOG_ONLY > 0)
* combineVerdict ensemble rule — THE critical path:
- Empty signals → safe
- Canary leak always blocks (regardless of ML signals)
- Both ML layers >= WARN → BLOCK (ensemble_agreement)
- Single layer >= BLOCK → WARN (single_layer_high) — the Stack Overflow
FP mitigation that prevents one classifier killing sessions alone
- Max-across-duplicates when multiple signals reference the same layer
* Canary generation + injection + recursive checking:
- Unique CANARY-XXXXXXXXXXXX tokens (>= 48 bits entropy)
- Recursive structure scan for tool_use inputs, nested URLs, commands
- Null / primitive handling doesn't throw
* Payload hashing (salted sha256) — deterministic per-device, differs across
payloads, 64-char hex shape
* logAttempt writes to ~/.gstack/security/attempts.jsonl
* writeSessionState + readSessionState round-trip (cross-process)
* getStatus returns valid SecurityStatus shape
* extractDomain returns hostname only, empty string on bad input
All 25 tests pass in 18ms — no ML, no network, no subprocess spawning.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(security): expose security status on /health for shield icon
The /health endpoint now returns a `security` field with the classifier
status, suitable for driving the sidepanel shield icon:
{
status: 'protected' | 'degraded' | 'inactive',
layers: { testsavant, transcript, canary },
lastUpdated: ISO8601
}
Backend plumbing:
* server.ts imports getStatus from security.ts (pure-string, safe in
compiled binary) and includes it in the /health response.
* sidebar-agent.ts writes ~/.gstack/security/session-state.json when the
classifier warmup completes (success OR failure). This is the cross-
process handoff — server.ts reads the state file via getStatus() to
surface the result to the sidepanel.
The sidepanel rendering (SVG shield icon + color states + tooltip) is a
follow-up commit in the extension/ code.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* docs(security): document the sidebar security stack in CLAUDE.md
Adds a security section to the Browser interaction block. Covers:
* Layered defense table showing which modules live where (content-security.ts
in both contexts vs security-classifier.ts only in sidebar-agent) and why
the split exists (onnxruntime-node incompatibility with compiled Bun)
* Threshold constants (0.85 / 0.60 / 0.40) and the ensemble rule that
prevents single-classifier false-positives (the Stack Overflow FP story)
* Env knobs — GSTACK_SECURITY_OFF kill switch, cache paths, salt file,
attack log rotation, session state file
This is the "before you modify the security stack, read this" doc. It lives
next to the existing Sidebar architecture note that points at
SIDEBAR_MESSAGE_FLOW.md.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* docs(todos): mark ML classifier v1 in-progress + file v2 follow-ups
Reframes the P0 item to reflect v1 scope (branch 2 architecture, TestSavantAI
pivot, what shipped) and splits v2 work into discrete TODOs:
* Shield icon + canary leak banner UI (P0, blocks v1 user-facing completion)
* Attack telemetry via gstack-telemetry-log (P1)
* Full BrowseSafe-Bench at gate tier (P2)
* Cross-user aggregate attack dashboard (P2)
* DeBERTa-v3 as third signal in ensemble (P2)
* Read/Glob/Grep ingress coverage (P2, flagged by Codex review)
* Adversarial + integration + smoke-bench test suites (P1)
* Bun-native 5ms inference (P3 research)
Each TODO carries What / Why / Context / Effort / Priority / Depends-on so
it's actionable by someone picking it up cold.

* feat(telemetry): add attack_attempt event type to gstack-telemetry-log
Extends the existing telemetry pipe with 5 new flags needed for prompt
injection attack reporting:
--url-domain hostname only (never path, never query)
--payload-hash salted sha256 hex (opaque — no payload content ever)
--confidence 0-1 (awk-validated + clamped; malformed → null)
--layer testsavant_content | transcript_classifier | aria_regex | canary
--verdict block | warn | log_only
Backward compatibility:
* Existing skill_run events still work — all new fields default to null
* Event schema is a superset of the old one; downstream edge function can
filter by event_type
No new auth, no new SDK, no new Supabase migration. The same tier gating
(community → upload, anonymous → local only, off → no-op) and the same
sync daemon carry the attack events. This is the "E6 RESOLVED" path from
the CEO plan — riding the existing pipe instead of spinning up parallel infra.
Verified end-to-end:
* attack_attempt event with all fields emits correctly to skill-usage.jsonl
* skill_run event with no security flags still works (backward compat)
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(security): wire logAttempt to gstack-telemetry-log (fire-and-forget)
Every local attempt.jsonl write now also triggers a subprocess call to
gstack-telemetry-log with the attack_attempt event type. The binary handles
tier gating internally (community → Supabase upload, anonymous → local
JSONL only, off → no-op), so security.ts doesn't need to re-check.
Binary resolution follows the skill preamble pattern — never relies on PATH,
which breaks in compiled-binary contexts:
1. ~/.claude/skills/gstack/bin/gstack-telemetry-log (global install)
2. .claude/skills/gstack/bin/gstack-telemetry-log (symlinked dev)
3. bin/gstack-telemetry-log (in-repo dev)
Fire-and-forget:
* spawn with stdio: 'ignore', detached: true, unref()
* .on('error') swallows failures
* Missing binary is non-fatal — local attempts.jsonl still gives audit trail
Never throws. Never blocks. Existing 37 security tests pass unchanged.

* feat(ui): add security banner markup + styles (approved variant A)
HTML + CSS for the canary leak / ML block banner. Structure matches the
approved mockup from /plan-design-review 2026-04-19 (variant A — centered
alert-heavy):
* Red alert-circle SVG icon (no stock shield, intentional — matches the
"serious but not scary" tone the review chose)
* "Session terminated" Satoshi Bold 18px red headline
* "— prompt injection detected from {domain}" DM Sans zinc subtitle
* Expandable "What happened" chevron button (aria-expanded/aria-controls)
* Layer list rendered in JetBrains Mono with amber tabular-nums scores
* Close X in top-right, 28px hit area, focus-visible amber outline
Enter animation: slide-down 8px + fade, 250ms, cubic-bezier(0.16,1,0.3,1) —
matches DESIGN.md motion spec. Respects `role="alert"` + `aria-live="assertive"`
so screen readers announce on appearance. Escape-to-dismiss hook is in the
JS follow-up commit.
Design tokens all via CSS variables (--error, --amber-400, --amber-500,
--zinc-*, --font-display, --font-mono, --radius-*) — already established in
the stylesheet. No new color constants introduced.
JS wiring lands in the next commit so this diff stays focused on
presentation layer only.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(ui): wire security banner to security_event + interactivity
Adds showSecurityBanner() and hideSecurityBanner() plus the addChatEntry
routing for entry.type === 'security_event'. When the sidebar-agent emits
a security_event (canary leak or ML BLOCK), the banner renders with:
* Title ("Session terminated")
* Subtitle with {domain} if present, otherwise generic
* Expandable layer list — each row: SECURITY_LAYER_LABELS[layer] +
confidence.toFixed(2) in mono. Readable + auditable — user can see
which layer fired at what score
Interactivity, wired once on DOMContentLoaded:
* Close X → hideSecurityBanner()
* Expand/collapse "What happened" → toggles details + aria-expanded +
chevron rotation (200ms css transition already in place)
* Escape key dismisses while banner is visible (a11y)
No shield icon yet — that's a separate commit that will consume the
`security` field now returned by /health.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(ui): add security shield icon in sidepanel header (3 states)
Small "SEC" badge in the top-right of the sidepanel that reflects the
security module's current state. Three states drive color:
protected green — all layers ok (TestSavantAI + transcript + canary)
degraded amber — one+ ML layer offline but canary + arch controls active
inactive red — security module crashed, arch controls only
Consumes /health.security (surfaced in commit

feat: GStack Browser — double-click AI browser with anti-bot stealth (#695)
* feat: CDP inspector module — persistent sessions, CSS cascade, style modification
New browse/src/cdp-inspector.ts with full CDP inspection engine:
- inspectElement() via CSS.getMatchedStylesForNode + DOM.getBoxModel
- modifyStyle() via CSS.setStyleTexts with headless page.evaluate fallback
- Persistent CDP session lifecycle (create, reuse, detach on nav, re-create)
- Specificity sorting, overridden property detection, UA rule filtering
- Modification history with undo support
- formatInspectorResult() for CLI output
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: browse server inspector endpoints + inspect/style/cleanup/prettyscreenshot CLI
Server endpoints: POST /inspector/pick, GET /inspector, POST /inspector/apply,
POST /inspector/reset, GET /inspector/history, GET /inspector/events (SSE).
CLI commands: inspect (CDP cascade), style (live CSS mod), cleanup (page clutter
removal), prettyscreenshot (clean screenshot pipeline).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: sidebar CSS inspector — element picker, box model, rule cascade, quick edit
Extension changes for the visual CSS inspector:
- inspector.js: element picker with hover highlight, CSS selector generation,
basic mode fallback (getComputedStyle + CSSOM), page alteration handlers
- inspector.css: picker overlay styles (blue highlight + tooltip)
- background.js: inspector message routing (picker <-> server <-> sidepanel)
- sidepanel: Inspector tab with box model viz (gstack palette), matched rules
with specificity badges, computed styles, click-to-edit quick edit,
Send to Agent/Code button, empty/loading/error states

* docs: document inspect, style, cleanup, prettyscreenshot browse commands
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: auto-track user-created tabs and handle tab close
browser-manager.ts changes:
- context.on('page') listener: automatically tracks tabs opened by the user
(Cmd+T, right-click open in new tab, window.open). Previously only
programmatic newTab() was tracked, so user tabs were invisible.
- page.on('close') handler in wirePageEvents: removes closed tabs from the
pages map and switches activeTabId to the last remaining tab.
- syncActiveTabByUrl: match Chrome extension's active tab URL to the correct
Playwright page for accurate tab identity.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: per-tab agent isolation via BROWSE_TAB environment variable
Prevents parallel sidebar agents from interfering with each other's tab context.
Three-layer fix:
- sidebar-agent.ts: passes BROWSE_TAB=<tabId> env var to each claude process,
per-tab processing set allows concurrent agents across tabs
- cli.ts: reads process.env.BROWSE_TAB and includes tabId in command request body
- server.ts: handleCommand() temporarily switches activeTabId when tabId is present,
restores after command completes (safe: Bun event loop is single-threaded)
Also: per-tab agent state (TabAgentState map), per-tab message queuing,
per-tab chat buffers, verbose streaming narration, stop button endpoint.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: sidebar per-tab chat context, tab bar sync, stop button, UX polish
Extension changes:
- sidepanel.js: per-tab chat history (tabChatHistories map), switchChatTab()
swaps entire chat view, browserTabActivated handler for instant tab sync,
stop button wired to /sidebar-agent/stop, pollTabs renders tab bar
- sidepanel.html: updated banner text ("Browser co-pilot"), stop button markup,
input placeholder "Ask about this page..."
- sidepanel.css: tab bar styles, stop button styles, loading state fixes
- background.js: chrome.tabs.onActivated sends browserTabActivated to sidepanel
with tab URL for instant tab switch detection
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test: per-tab isolation, BROWSE_TAB pinning, tab tracking, sidebar UX
sidebar-agent.test.ts (new tests):
- BROWSE_TAB env var passed to claude process
- CLI reads BROWSE_TAB and sends tabId in body
- handleCommand accepts tabId, saves/restores activeTabId
- Tab pinning only activates when tabId provided
- Per-tab agent state, queue, concurrency
- processingTabs set for parallel agents
sidebar-ux.test.ts (new tests):
- context.on('page') tracks user-created tabs
- page.on('close') removes tabs from pages map
- Tab isolation uses BROWSE_TAB not system prompt hack
- Per-tab chat context in sidepanel
- Tab bar rendering, stop button, banner text
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: resolve merge conflicts — keep security defenses + per-tab isolation
Merged main's security improvements (XML escaping, prompt injection defense,
allowed commands whitelist, --model opus, Write tool, stderr capture) with
our branch's per-tab isolation (BROWSE_TAB env var, processingTabs set,
no --resume). Updated test expectations for expanded system prompt.

* chore: bump version and changelog (v0.13.9.0)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: add inspector message types to background.js allowlist
Pre-existing bug found by Codex: ALLOWED_TYPES in background.js was missing
all inspector message types (startInspector, stopInspector, elementPicked,
pickerCancelled, applyStyle, toggleClass, injectCSS, resetAll, inspectResult).
Messages were silently rejected, making the inspector broken on ALL pages.
Also: separate executeScript and insertCSS into individual try blocks in
injectInspector(), store inspectorMode for routing, and add content.js
fallback when script injection fails (CSP, chrome:// pages).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: basic element picker in content.js for CSP-restricted pages
When inspector.js can't be injected (CSP, chrome:// pages), content.js
provides a basic picker using getComputedStyle + CSSOM:
- startBasicPicker/stopBasicPicker message handlers
- captureBasicData() with ~30 key CSS properties, box model, matched rules
- Hover highlight with outline save/restore (never leaves artifacts)
- Click uses e.target directly (no re-querying by selector)
- Sends inspectResult with mode:'basic' for sidebar rendering
- Escape key cancels picker and restores outlines
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: cleanup + screenshot buttons in sidebar inspector toolbar
Two action buttons in the inspector toolbar:
- Cleanup (🧹): POSTs cleanup --all to server, shows spinner, chat
notification on success, resets inspector state (element may be removed)
- Screenshot (📸): POSTs screenshot to server, shows spinner, chat
notification with saved file path
Shared infrastructure:
- .inspector-action-btn CSS with loading spinner via ::after pseudo-element
- chat-notification type in addChatEntry() for system messages
- package.json version bump to 0.13.9.0
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test: inspector allowlist, CSP fallback, cleanup/screenshot buttons
16 new tests in sidebar-ux.test.ts:
- Inspector message allowlist includes all inspector types
- content.js basic picker (startBasicPicker, captureBasicData, CSSOM,
outline save/restore, inspectResult with mode basic, Escape cleanup)
- background.js CSP fallback (separate try blocks, inspectorMode, fallback)
- Cleanup button (POST /command, inspector reset after success)
- Screenshot button (POST /command, notification rendering)
- Chat notification type and CSS styles

* feat: cleanup + screenshot buttons in chat toolbar (not just inspector)
Quick actions toolbar (🧹 Cleanup, 📸 Screenshot) now appears above the chat
input, always visible. Both inspector and chat buttons share runCleanup() and
runScreenshot() helper functions. Clicking either set shows loading state on
both simultaneously.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test: chat toolbar buttons, shared helpers, quick-action-btn styles
Tests that chat toolbar exists (chat-cleanup-btn, chat-screenshot-btn,
quick-actions container), CSS styles (.quick-action-btn, .quick-action-btn.loading),
shared runCleanup/runScreenshot helper functions, and cleanup inspector reset.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: aggressive cleanup heuristics — overlays, scroll unlock, blur removal
Massively expanded CLEANUP_SELECTORS with patterns from uBlock Origin and
Readability.js research:
- ads: 30+ selectors (Google, Amazon, Outbrain, Taboola, Criteo, etc.)
- cookies: OneTrust, Cookiebot, TrustArc, Quantcast + generic patterns
- overlays (NEW): paywalls, newsletter popups, interstitials, push prompts,
app download banners, survey modals
- social: follow prompts, share tools
- Cleanup now defaults to --all when no args (sidebar button fix)
- Uses !important on all display:none (overrides inline styles)
- Unlocks body/html scroll (overflow:hidden from modal lockout)
- Removes blur/filter effects (paywall content blur)
- Removes max-height truncation (article teaser truncation)
- Collapses empty ad placeholder whitespace (empty divs after ad removal)
- Skips gstack-ctrl indicator in sticky removal
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: disable action buttons when disconnected, no error spam
- setActionButtonsEnabled() toggles .disabled class on all cleanup/screenshot
buttons (both chat toolbar and inspector toolbar)
- Called with false in updateConnection when server URL is null
- Called with true when connection established
- runCleanup/runScreenshot silently return when disconnected instead of
showing 'Not connected' error notifications
- CSS .disabled style: pointer-events:none, opacity:0.3, cursor:not-allowed
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test: cleanup heuristics, button disabled state, overlay selectors
17 new tests:
- cleanup defaults to --all on empty args
- CLEANUP_SELECTORS overlays category (paywall, newsletter, interstitial)
- Major ad networks in selectors (doubleclick, taboola, criteo, etc.)
- Major consent frameworks (OneTrust, Cookiebot, TrustArc, Quantcast)
- !important override for inline styles
- Scroll unlock (body overflow:hidden)
- Blur removal (paywall content blur)
- Article truncation removal (max-height)
- Empty placeholder collapse
- gstack-ctrl indicator skip in sticky cleanup
- setActionButtonsEnabled function
- Buttons disabled when disconnected
- No error spam from cleanup/screenshot when disconnected
- CSS disabled styles for action buttons

* feat: LLM-based page cleanup — agent analyzes page semantically
Instead of brittle CSS selectors, the cleanup button now sends a prompt to
the sidebar agent (which IS an LLM). The agent:
1. Runs deterministic $B cleanup --all as a quick first pass
2. Takes a snapshot to see what's left
3. Analyzes the page semantically to identify remaining clutter
4. Removes elements intelligently, preserving site branding
This means cleanup works correctly on any site without site-specific selectors.
The LLM understands that "Your Daily Puzzles" is clutter, "ADVERTISEMENT" is
junk, but the SF Chronicle masthead should stay.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: aggressive cleanup heuristics + preserve top nav bar
Deterministic cleanup improvements (used as first pass before LLM analysis):
- New 'clutter' category: audio players, podcast widgets, sidebar puzzles/games,
recirculation widgets (taboola, outbrain, nativo), cross-promotion banners
- Text-content detection: removes "ADVERTISEMENT", "Article continues below",
"Sponsored", "Paid content" labels and their parent wrappers
- Sticky fix: preserves the topmost full-width element near viewport top (site
nav bar) instead of hiding all sticky/fixed elements. Sorts by vertical
position, preserves the first one that spans >80% viewport width.
Tests: clutter category, ad label removal, nav bar preservation logic.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test: LLM-based cleanup architecture, deterministic heuristics, sticky nav
22 new tests covering:
- Cleanup button uses /sidebar-command (agent) not /command (deterministic)
- Cleanup prompt includes deterministic first pass + agent snapshot analysis
- Cleanup prompt lists specific clutter categories for agent guidance
- Cleanup prompt preserves site identity (masthead, headline, body, byline)
- Cleanup prompt instructs scroll unlock and $B eval removal
- Loading state management (async agent, setTimeout)
- Deterministic clutter: audio/podcast, games/puzzles, recirculation
- Ad label text patterns (ADVERTISEMENT, Sponsored, Article continues)
- Ad label parent wrapper hiding for small containers
- Sticky nav preservation (sort by position, first full-width near top)

* feat: GStack Browser stealth + branding — anti-bot patches, custom UA, rebrand
- Add GSTACK_CHROMIUM_PATH env var for custom Chromium binary
- Add BROWSE_EXTENSIONS_DIR env var for extension path override
- Move auth token to /health endpoint (fixes read-only .app bundles)
- Anti-bot stealth: disable navigator.webdriver, fake plugins, languages
- Custom user agent: Chrome/<version> GStackBrowser (auto-detects version)
- Rebrand Chromium plist to "GStack Browser" at launch time
- Update security test to match new token-via-health approach
* feat: GStack Browser .app bundle — launcher script + build system
- scripts/app/gstack-browser: dual-mode launcher (dev + .app bundle)
- scripts/build-app.sh: compiles binary, bundles Chromium + extension, creates DMG
- Rebrands Chromium plist during build for "GStack Browser" in menu bar
- 389MB .app, 189MB compressed DMG, launches in ~5s
* docs: GStack Browser V0 master plan — AI-native development browser vision
5-phase roadmap from .app wrapper through Chromium fork, 9 capability
visions, competitive landscape, architecture diagrams, design system.
* fix: restore package.json and sync version to 0.14.3.0
* chore: bump version and changelog (v0.14.4.0)
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* chore: gitignore top-level dist/ (GStack Browser build output)
* feat: GStack Browser icon — custom .icns replaces Chromium's Dock icon
- Generated 1024px icon: dark terminal window with amber prompt cursor
- Converted to .icns with all macOS sizes (16-1024px, 1x and 2x)
- build-app.sh copies icon into both the outer .app and bundled Chromium's
Resources (Chromium's process owns the Dock icon, not the launcher)
- browser-manager.ts patches Chromium's icon at runtime for dev mode too
- Both the Dock and Cmd+Tab now show the GStack icon
* feat: rename /connect-chrome → /open-gstack-browser
- Rename skill directory + update frontmatter name and description
- Update SKILL.md.tmpl to reference GStack Browser branding/stealth
- Create connect-chrome symlink for backwards compatibility
- Setup script creates /connect-chrome alias in .claude/skills/
- Fix package.json version sync (0.14.5.0 → 0.14.6.0)
* feat: rename /connect-chrome → /open-gstack-browser across all references
Update README skill lists, docs/skills.md deep dive, extension sidepanel
banner copy button, and reconnect clipboard text.
* feat: left-align sidebar UI + extension-ready event for welcome page
- Left-align all sidebar text (chat welcome, loading, empty states,
notifications, inspector empty, session placeholder)
- Dispatch 'gstack-extension-ready' CustomEvent from content.js so
the welcome page can detect when the sidebar is active
* chore: add GStack Browser TODOs — CDP stealth patches + Chromium fork
P1: rebrowser-style postinstall patcher for Playwright 1.58.2 (suppress
Runtime.enable, addBinding context discovery, 6 files, ~200 lines).
P2: long-term Chromium fork for permanent stealth + native sidebar.
* chore: regenerate open-gstack-browser/SKILL.md from template
Fix timeline skill name (connect-chrome → open-gstack-browser) and
preamble formatting from merge with main's updated template.
* feat: welcome page served from browse server on headed launch
- Add /welcome endpoint to server.ts, serves welcome.html
- Navigate to /welcome after server starts (not during launchHeaded,
which runs before the server is listening)
- welcome.html bundled in browse/src/ for portability
* feat: auto-open sidebar on every browser launch, not just first install
- Add top-level setTimeout in background.js that fires on every service
worker startup (onInstalled only fires on install/update)
- Remove misaligned arrow from welcome page, replace with text fallback
that hides when extension content script fires gstack-extension-ready
* fix: sidebar auto-open retry with backoff + welcome page tests
- Replace single-attempt sidePanel.open() with autoOpenSidePanel() that
retries up to 5 times with 500ms-5000ms backoff
- Fire on both onInstalled AND every service worker startup
- Remove misaligned arrow from welcome page, replace with text fallback
- Add 12 tests: welcome page structure, /welcome endpoint, headed launch
navigation timing, sidebar auto-open retry logic, extension-ready event
* feat: reload button in sidebar footer
Adds a "reload" button next to "debug" and "clear" in the sidebar
footer. Calls location.reload() to fully refresh the side panel,
re-run connection logic, and clear stale state.
* feat: right-pointing arrow hint for sidebar on welcome page
Replace invisible text fallback with visible amber bubble + animated
right arrow (→) pointing toward where the sidebar opens. Always correct
regardless of window size (unlike the old up arrow at toolbar chrome).
* fix: sidebar auth race — pass token in getPort response
The sidebar called tryConnect() → getPort → got {port, connected} but
NO token. All subsequent requests (SSE, chat poll) failed with 401.
The token only arrived later via the health broadcast, but by then
the SSE connection was already broken.
Fix: include authToken in the getPort response so the sidebar has
the token from its very first connection attempt.
* feat: sidebar debug visibility + auth race tests
- Show attempt count in loading screen ("Connecting... attempt 3")
- After 5 failed attempts, show debug details (port, connected, token)
so stuck users can see exactly what's failing
- Add 4 tests: getPort includes token, tryConnect uses token,
dead state exists with MAX_RECONNECT_ATTEMPTS, reconnectAttempts visible
* fix: startup health check retries every 1s instead of 10s
Root cause: extension service worker starts before Bun.serve() is
listening. First checkHealth() fails, next attempt is 10 seconds
later. User stares at "Connecting..." for 10 seconds.
Fix: retry every 1s for up to 15 attempts on startup, then switch
to 10s polling once connected (or after 15s gives up). Sidebar
should connect within 1-2 seconds of server becoming available.
3 new tests verify the fast-retry → slow-poll transition.
* feat: detailed step-by-step status in sidebar loading screen
Replace useless "Connecting..." with real-time debug info:
- "Looking for browse server... (attempt N)"
- Shows port, server responding status, token status
- Shows chrome.runtime errors if extension messaging fails
- Tells user to run /open-gstack-browser if server not found
* fix: sidebar connects directly to /health instead of waiting for background
Root cause: sidepanel asked background "are you connected?" but background's
health check hadn't succeeded yet (1-10s gap). Sidepanel waited forever.
Fix: when background says not connected, sidepanel hits /health directly
with fetch(). Gets the token from the response. Bypasses background
entirely for initial connection. Shows step-by-step debug info:
"Checking server directly... port: 34567 / Trying GET /health..."
* fix: suppress fake "session ended" and timeout errors in sidebar
Two issues making the sidebar look broken when it's actually working:
1. "Timed out after 300s" error displayed after agent_done — this is a
cleanup timer, not a real error. Now suppressed when no active session.
2. "(session ended)" text appended on every idle poll — removed entirely.
The thinking spinner is cleaned up silently instead.
* fix: sidebar agent passes BROWSE_PORT to child claude
Ensures the child claude process connects to the existing headed
browse server (port 34567) instead of spawning a new headless one.
Without this, sidebar chat commands run in an invisible browser.
* feat: BROWSE_NO_AUTOSTART prevents sidebar from spawning headless browser
When set, the browse CLI refuses to start a new server and exits with
a clear error: "Server not available, run /open-gstack-browser to restart."
The sidebar agent sets this so users never get an invisible headless
browser when the headed one is closed.
* test: BROWSE_NO_AUTOSTART guard in CLI + sidebar-agent env vars
5 tests: CLI checks env var before starting server, shows actionable
error, sidebar-agent sets the flag + BROWSE_PORT, guard runs before
lock acquisition to prevent stale lock files.
* fix: stale auth token causes Unauthorized + invisible error text
background.js checkHealth() never refreshed authToken from /health responses,
so when the browse server restarted with a new token, all sidebar-command
requests got 401 Unauthorized forever.
Also: error placeholder text was #3f3f46 on #0C0C0C (nearly invisible).
Now shows in red to match the error border.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: replace 40+ silent catch blocks with debug logging
Every empty catch {} in sidepanel.js, sidebar-agent.ts now logs with
[gstack sidebar] or [sidebar-agent] prefix. Chat poll 401s, stop agent,
tab poll, clear chat, SSE parse, refs fetch, stream JSON parse, queue
read/parse, process kill — all now visible in console.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: noisy debug logging + auto model routing in browse server
Server-side silent catch blocks (22 instances) now log with [browse] prefix:
chat persistence, session save/load, agent kill, tab pin/restore, welcome
page, buffer flush, worktree cleanup, lock files, SSE streams.
Also adds pickSidebarModel() — routes sidebar messages to sonnet for
navigation/interaction (click, goto, fill, screenshot) and opus for
analysis/comprehension (summarize, describe, find bugs). Sonnet is
~4x faster for action commands with zero quality difference.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test: update sidebar tests for model router + longer stopAgent slice
- stopAgent slice 800→1000 to accommodate added error logging lines
- Replace hardcoded opus assertion with model router assertions
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: sidebar arrow hint stays visible until sidebar actually opens
Previously the welcome page arrow hid immediately when the extension's
content script loaded — but extension loaded ≠ sidebar open. Now the
signal flow is: sidepanel connects → tells background.js → relays to
content script → dispatches gstack-extension-ready → arrow hides.
Adds welcome-page.test.ts: 14 tests verifying arrow, branding, feature
cards, dark theme, and auto-hide behavior via real HTTP server.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test: arrow hide signal chain (4-step) + stale session-ended assertion
8 new tests verify the sidebarOpened → background → content → welcome
signal chain. Updates stale "(session ended)" test that checked for
text removed in a prior commit.

* fix: preserve optimistic UI during tab switch on first message
When the user sends a message and the server assigns it to a new tab
(because Chrome's active tab changed), switchChatTab() was blowing away
the optimistic user bubble and thinking dots with a welcome screen.
Now preserves the current DOM if we're mid-send with a thinking indicator.

* docs: sidebar message flow architecture doc + CLAUDE.md pointer
SIDEBAR_MESSAGE_FLOW.md documents the full init timeline, message flow
(user types → claude responds), auth token chain, arrow hint signal
chain, model routing, tab concurrency, and known failure modes.
CLAUDE.md now tells you to read it before touching sidebar files.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: sidebar chat resets idle timer + shutdown kills sidebar-agent
Two fixes for the "browser died while chatting" problem:
1. /sidebar-command now calls resetIdleTimer(). Previously only CLI
commands reset it, so the server would shut down after 30 min even
while the user was actively chatting in the sidebar.
2. shutdown() now pkills the sidebar-agent daemon. Previously the agent
survived server shutdown, kept polling a dead server, and spawned
confused claude processes that auto-started headless browsers.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: disable idle timeout in headed mode — browser lives until closed
The 30-minute idle timeout only applies to headless mode now. In headed
mode the user is looking at the Chrome window, so auto-shutdown is wrong.
The browser stays alive until explicit disconnect or window close.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: cookies button in sidebar footer opens cookie picker
One-click cookie import from the sidebar. Navigates the headed browser
to /cookie-picker where you can select which domains to import from
your real Chrome profile.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* docs: update project documentation for GStack Browser improvements
README.md: updated Real browser mode and sidebar agent sections with
model routing, cookie import button, no idle timeout in headed mode.
Updated skill table entries for /browse and /open-gstack-browser.
docs/skills.md: updated /open-gstack-browser deep dive with model
routing and cookie import details.
GSTACK_BROWSER_V0.md: added 6 new SHIPPED items to implementation
status table (model routing, debug logging, idle timeout, cookie
button, arrow hint, architecture doc).
TODOS.md: marked "Sidebar agent Write tool + error visibility" as
SHIPPED. Added new P2 TODO for direct API calls to eliminate
claude -p startup tax.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add Claude Code terminal example to welcome page TRY IT NOW
Fifth example shows the parent agent workflow: navigate, extract CSS,
write to file. The other four are all sidebar-only. This one shows
co-presence — the Claude Code session that launched the browser can
also control it directly.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: hide internal tool-result file reads from sidebar activity
Claude reads its own ~/.claude/projects/.../tool-results/ files as
internal plumbing. These showed up as long unreadable paths in the
sidebar. Now: describeToolCall returns empty for tool-result reads,
and the sidebar skips rendering tool_use entries with no description.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: collapse tool calls into "See reasoning" disclosure on completion
While the agent is working, tool calls stream live so you can watch
progress. When the agent finishes, all tool calls collapse into a
"See reasoning (N steps)" disclosure. Click to expand and see what
the agent did. The final text answer stays visible.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test: 17 new tests for recent sidebar fixes
Covers: tool-result file filtering, empty tool_use skip, reasoning
disclosure collapse, idle timeout headed mode bypass, sidebar-command
idle reset, shutdown sidebar-agent kill, cookie button, and model
routing analysis-before-action priority.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: move cookies button to quick actions toolbar
Cookies now sits next to Cleanup and Screenshot as a primary action
button (🍪 Cookies) instead of buried in the footer. Same behavior,
more discoverable.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add instructional text to cookie picker page
"Select the domains of cookies you want to import to GStack Browser.
You'll be able to browse those sites with the same login as your
other browser."
Also fixes stale test that expected hardcoded '--model', 'opus'.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: 6-card welcome page with cookie import + dual-agent cards
3x2 grid layout (was 2x2). New cards: "Import your cookies" (click
🍪 Cookies to import login sessions from Chrome/Arc/Brave) and
"Or use your main agent" (your Claude Code terminal also controls
this browser). Responsive: 3 cols > 2 cols > 1 col.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: move sidebar arrow hint to top-right instead of vertically centered
The arrow was centered vertically which put it behind the feature cards.
Now positioned at top: 80px where there's open space and it's more visible.

feat: sidebar CSS inspector + per-tab agents (v0.13.9.0) (#650)
* feat: CDP inspector module — persistent sessions, CSS cascade, style modification
New browse/src/cdp-inspector.ts with full CDP inspection engine:
- inspectElement() via CSS.getMatchedStylesForNode + DOM.getBoxModel
- modifyStyle() via CSS.setStyleTexts with headless page.evaluate fallback
- Persistent CDP session lifecycle (create, reuse, detach on nav, re-create)
- Specificity sorting, overridden property detection, UA rule filtering
- Modification history with undo support
- formatInspectorResult() for CLI output
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: browse server inspector endpoints + inspect/style/cleanup/prettyscreenshot CLI
Server endpoints: POST /inspector/pick, GET /inspector, POST /inspector/apply,
POST /inspector/reset, GET /inspector/history, GET /inspector/events (SSE).
CLI commands: inspect (CDP cascade), style (live CSS mod), cleanup (page clutter
removal), prettyscreenshot (clean screenshot pipeline).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: sidebar CSS inspector — element picker, box model, rule cascade, quick edit
Extension changes for the visual CSS inspector:
- inspector.js: element picker with hover highlight, CSS selector generation,
basic mode fallback (getComputedStyle + CSSOM), page alteration handlers
- inspector.css: picker overlay styles (blue highlight + tooltip)
- background.js: inspector message routing (picker <-> server <-> sidepanel)
- sidepanel: Inspector tab with box model viz (gstack palette), matched rules
with specificity badges, computed styles, click-to-edit quick edit,
Send to Agent/Code button, empty/loading/error states
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* docs: document inspect, style, cleanup, prettyscreenshot browse commands
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: auto-track user-created tabs and handle tab close
browser-manager.ts changes:
- context.on('page') listener: automatically tracks tabs opened by the user
(Cmd+T, right-click open in new tab, window.open). Previously only
programmatic newTab() was tracked, so user tabs were invisible.
- page.on('close') handler in wirePageEvents: removes closed tabs from the
pages map and switches activeTabId to the last remaining tab.
- syncActiveTabByUrl: match Chrome extension's active tab URL to the correct
Playwright page for accurate tab identity.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: per-tab agent isolation via BROWSE_TAB environment variable
Prevents parallel sidebar agents from interfering with each other's tab context.
Three-layer fix:
- sidebar-agent.ts: passes BROWSE_TAB=<tabId> env var to each claude process,
per-tab processing set allows concurrent agents across tabs
- cli.ts: reads process.env.BROWSE_TAB and includes tabId in command request body
- server.ts: handleCommand() temporarily switches activeTabId when tabId is present,
restores after command completes (safe: Bun event loop is single-threaded)
Also: per-tab agent state (TabAgentState map), per-tab message queuing,
per-tab chat buffers, verbose streaming narration, stop button endpoint.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: sidebar per-tab chat context, tab bar sync, stop button, UX polish
Extension changes:
- sidepanel.js: per-tab chat history (tabChatHistories map), switchChatTab()
swaps entire chat view, browserTabActivated handler for instant tab sync,
stop button wired to /sidebar-agent/stop, pollTabs renders tab bar
- sidepanel.html: updated banner text ("Browser co-pilot"), stop button markup,
input placeholder "Ask about this page..."
- sidepanel.css: tab bar styles, stop button styles, loading state fixes
- background.js: chrome.tabs.onActivated sends browserTabActivated to sidepanel
with tab URL for instant tab switch detection
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test: per-tab isolation, BROWSE_TAB pinning, tab tracking, sidebar UX
sidebar-agent.test.ts (new tests):
- BROWSE_TAB env var passed to claude process
- CLI reads BROWSE_TAB and sends tabId in body
- handleCommand accepts tabId, saves/restores activeTabId
- Tab pinning only activates when tabId provided
- Per-tab agent state, queue, concurrency
- processingTabs set for parallel agents
sidebar-ux.test.ts (new tests):
- context.on('page') tracks user-created tabs
- page.on('close') removes tabs from pages map
- Tab isolation uses BROWSE_TAB not system prompt hack
- Per-tab chat context in sidepanel
- Tab bar rendering, stop button, banner text
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: resolve merge conflicts — keep security defenses + per-tab isolation
Merged main's security improvements (XML escaping, prompt injection defense,
allowed commands whitelist, --model opus, Write tool, stderr capture) with
our branch's per-tab isolation (BROWSE_TAB env var, processingTabs set,
no --resume). Updated test expectations for expanded system prompt.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* chore: bump version and changelog (v0.13.9.0)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: add inspector message types to background.js allowlist
Pre-existing bug found by Codex: ALLOWED_TYPES in background.js was missing
all inspector message types (startInspector, stopInspector, elementPicked,
pickerCancelled, applyStyle, toggleClass, injectCSS, resetAll, inspectResult).
Messages were silently rejected, making the inspector broken on ALL pages.
Also: separate executeScript and insertCSS into individual try blocks in
injectInspector(), store inspectorMode for routing, and add content.js
fallback when script injection fails (CSP, chrome:// pages).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: basic element picker in content.js for CSP-restricted pages
When inspector.js can't be injected (CSP, chrome:// pages), content.js
provides a basic picker using getComputedStyle + CSSOM:
- startBasicPicker/stopBasicPicker message handlers
- captureBasicData() with ~30 key CSS properties, box model, matched rules
- Hover highlight with outline save/restore (never leaves artifacts)
- Click uses e.target directly (no re-querying by selector)
- Sends inspectResult with mode:'basic' for sidebar rendering
- Escape key cancels picker and restores outlines
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: cleanup + screenshot buttons in sidebar inspector toolbar
Two action buttons in the inspector toolbar:
- Cleanup (🧹): POSTs cleanup --all to server, shows spinner, chat
notification on success, resets inspector state (element may be removed)
- Screenshot (📸): POSTs screenshot to server, shows spinner, chat
notification with saved file path
Shared infrastructure:
- .inspector-action-btn CSS with loading spinner via ::after pseudo-element
- chat-notification type in addChatEntry() for system messages
- package.json version bump to 0.13.9.0
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test: inspector allowlist, CSP fallback, cleanup/screenshot buttons
16 new tests in sidebar-ux.test.ts:
- Inspector message allowlist includes all inspector types
- content.js basic picker (startBasicPicker, captureBasicData, CSSOM,
outline save/restore, inspectResult with mode basic, Escape cleanup)
- background.js CSP fallback (separate try blocks, inspectorMode, fallback)
- Cleanup button (POST /command, inspector reset after success)
- Screenshot button (POST /command, notification rendering)
- Chat notification type and CSS styles
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* docs: update project documentation for v0.13.9.0
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: cleanup + screenshot buttons in chat toolbar (not just inspector)
Quick actions toolbar (🧹 Cleanup, 📸 Screenshot) now appears above the chat
input, always visible. Both inspector and chat buttons share runCleanup() and
runScreenshot() helper functions. Clicking either set shows loading state on
both simultaneously.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test: chat toolbar buttons, shared helpers, quick-action-btn styles
Tests that chat toolbar exists (chat-cleanup-btn, chat-screenshot-btn,
quick-actions container), CSS styles (.quick-action-btn, .quick-action-btn.loading),
shared runCleanup/runScreenshot helper functions, and cleanup inspector reset.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: aggressive cleanup heuristics — overlays, scroll unlock, blur removal
Massively expanded CLEANUP_SELECTORS with patterns from uBlock Origin and
Readability.js research:
- ads: 30+ selectors (Google, Amazon, Outbrain, Taboola, Criteo, etc.)
- cookies: OneTrust, Cookiebot, TrustArc, Quantcast + generic patterns
- overlays (NEW): paywalls, newsletter popups, interstitials, push prompts,
app download banners, survey modals
- social: follow prompts, share tools
- Cleanup now defaults to --all when no args (sidebar button fix)
- Uses !important on all display:none (overrides inline styles)
- Unlocks body/html scroll (overflow:hidden from modal lockout)
- Removes blur/filter effects (paywall content blur)
- Removes max-height truncation (article teaser truncation)
- Collapses empty ad placeholder whitespace (empty divs after ad removal)
- Skips gstack-ctrl indicator in sticky removal
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: disable action buttons when disconnected, no error spam
- setActionButtonsEnabled() toggles .disabled class on all cleanup/screenshot
buttons (both chat toolbar and inspector toolbar)
- Called with false in updateConnection when server URL is null
- Called with true when connection established
- runCleanup/runScreenshot silently return when disconnected instead of
showing 'Not connected' error notifications
- CSS .disabled style: pointer-events:none, opacity:0.3, cursor:not-allowed
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test: cleanup heuristics, button disabled state, overlay selectors
17 new tests:
- cleanup defaults to --all on empty args
- CLEANUP_SELECTORS overlays category (paywall, newsletter, interstitial)
- Major ad networks in selectors (doubleclick, taboola, criteo, etc.)
- Major consent frameworks (OneTrust, Cookiebot, TrustArc, Quantcast)
- !important override for inline styles
- Scroll unlock (body overflow:hidden)
- Blur removal (paywall content blur)
- Article truncation removal (max-height)
- Empty placeholder collapse
- gstack-ctrl indicator skip in sticky cleanup
- setActionButtonsEnabled function
- Buttons disabled when disconnected
- No error spam from cleanup/screenshot when disconnected
- CSS disabled styles for action buttons
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: LLM-based page cleanup — agent analyzes page semantically
Instead of brittle CSS selectors, the cleanup button now sends a prompt to
the sidebar agent (which IS an LLM). The agent:
1. Runs deterministic $B cleanup --all as a quick first pass
2. Takes a snapshot to see what's left
3. Analyzes the page semantically to identify remaining clutter
4. Removes elements intelligently, preserving site branding
This means cleanup works correctly on any site without site-specific selectors.
The LLM understands that "Your Daily Puzzles" is clutter, "ADVERTISEMENT" is
junk, but the SF Chronicle masthead should stay.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: aggressive cleanup heuristics + preserve top nav bar
Deterministic cleanup improvements (used as first pass before LLM analysis):
- New 'clutter' category: audio players, podcast widgets, sidebar puzzles/games,
recirculation widgets (taboola, outbrain, nativo), cross-promotion banners
- Text-content detection: removes "ADVERTISEMENT", "Article continues below",
"Sponsored", "Paid content" labels and their parent wrappers
- Sticky fix: preserves the topmost full-width element near viewport top (site
nav bar) instead of hiding all sticky/fixed elements. Sorts by vertical
position, preserves the first one that spans >80% viewport width.
Tests: clutter category, ad label removal, nav bar preservation logic.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test: LLM-based cleanup architecture, deterministic heuristics, sticky nav
22 new tests covering:
- Cleanup button uses /sidebar-command (agent) not /command (deterministic)
- Cleanup prompt includes deterministic first pass + agent snapshot analysis
- Cleanup prompt lists specific clutter categories for agent guidance
- Cleanup prompt preserves site identity (masthead, headline, body, byline)
- Cleanup prompt instructs scroll unlock and $B eval removal
- Loading state management (async agent, setTimeout)
- Deterministic clutter: audio/podcast, games/puzzles, recirculation
- Ad label text patterns (ADVERTISEMENT, Sponsored, Article continues)
- Ad label parent wrapper hiding for small containers
- Sticky nav preservation (sort by position, first full-width near top)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: prevent repeat chat message rendering on reconnect/replay
Root cause: server persists chat to disk (chat.jsonl) and replays on restart.
Client had no dedup, so every reconnect re-rendered the entire history.
Messages from an old HN session would repeat endlessly on the SF Chronicle tab.
Fix: renderedEntryIds Set tracks which entry IDs have been rendered. addChatEntry
skips entries already in the set. Entries without an id (local notifications)
bypass the check. Clear chat resets the set.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: agent stops when done, no focus stealing, opus for prompt injection safety
Three fixes for sidebar agent UX:
- System prompt: "Be CONCISE. STOP as soon as the task is done. Do NOT keep
exploring or doing bonus work." Prevents agent from endlessly taking
screenshots and highlighting elements after answering the question.
- switchTab(id, opts): new bringToFront option. Internal tab pinning
(BROWSE_TAB) uses bringToFront: false so agent commands never steal
window focus from the user's active app.
- Keep opus model (not sonnet) for prompt injection resistance on untrusted
web pages. Remove Write from allowedTools (agent only needs Bash for $B).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test: agent conciseness, focus stealing, opus model, switchTab opts
Tests for the three UX fixes:
- System prompt contains STOP/CONCISE/Do NOT keep exploring
- sidebar agent uses opus (not sonnet) for prompt injection resistance
- switchTab has bringToFront option, defaults to true (opt-out)
- handleCommand tab pinning uses bringToFront: false (no focus steal)
- Updated stale tests: switchTab signature, allowedTools excludes Write,
narration -> conciseness, tab pinning restore calls
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test: sidebar CSS interaction E2E — HN comment highlight round-trip
New E2E test (periodic tier, ~$2/run) that exercises the full sidebar
agent pipeline with CSS interaction:
1. Agent navigates to Hacker News
2. Clicks into the top story's comments
3. Reads comments and identifies the most insightful one
4. Highlights it with a 4px solid orange outline via style injection
Tests: navigation, snapshot, text reading, LLM judgment, CSS modification.
Requires real browser + real Claude (ANTHROPIC_API_KEY).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: sidebar CSS E2E test — correct idle timeout (ms not s), pipe stdio
Root cause of test failure: BROWSE_IDLE_TIMEOUT is in milliseconds, not
seconds. '600' = 0.6 seconds, server died immediately after health check.
Fixed to '600000' (10 minutes).
Also: use 'pipe' stdio instead of file descriptors (closing fds kills child
on macOS/bun), catch ConnectionRefused on poll retry, 4 min poll timeout
for the multi-step opus task.
Test passes: agent navigates to HN, reads comments, identifies most
insightful one, highlights it with orange CSS, stops. 114s, $0.00.

feat: headed mode + sidebar agent + Chrome extension (v0.12.0) (#517)
* feat: CDP connect — control real Chrome/Comet via Playwright
Add `connectCDP()` to BrowserManager: connects to a running browser via
Chrome DevTools Protocol. All existing browse commands work unchanged
through Playwright's abstraction layer.
- chrome-launcher.ts: browser discovery, CDP probe, auto-relaunch with rollback
- browser-manager.ts: connectCDP(), mode guards (close/closeTab/recreateContext/handoff),
auto-reconnect on browser restart, getRefMap() for extension API
- server.ts: CDP branch in start(), /health gains mode field, /refs endpoint,
idle timer only resets on /command (not passive endpoints)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: browse connect/disconnect/focus CLI commands
- connect: pre-server command that discovers browser, starts server in CDP mode
- disconnect: drops CDP connection, restarts in headless mode
- focus: brings browser window to foreground via osascript (macOS)
- status: now shows Mode: cdp | launched | headed
- startServer() accepts extra env vars for CDP URL/port passthrough
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: CDP-aware skill templates — skip cookie import in real browser mode
Skills now check `$B status` for CDP mode and skip:
- /qa: cookie import prompt, user-agent override, headless workarounds
- /design-review: cookie import for authenticated pages
- /setup-browser-cookies: returns "not needed" in CDP mode
Regenerated SKILL.md files from updated templates.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: activity streaming — SSE endpoint for Chrome extension Side Panel
Real-time browse command feed via Server-Sent Events:
- activity.ts: ActivityEntry type, CircularBuffer (capacity 1000), privacy
filtering (redacts passwords, auth tokens, sensitive URL params),
cursor-based gap detection, async subscriber notification
- server.ts: /activity/stream SSE, /activity/history REST, handleCommand
instrumented with command_start/command_end events
- 18 unit tests for filterArgs privacy, emitActivity, subscribe lifecycle
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: Chrome extension Side Panel + Conductor API proposal
Chrome extension (Manifest V3, sideload):
- Side Panel with live activity feed, @ref overlays, dark terminal aesthetic
- Background worker: health polling, SSE relay, ref fetching
- Popup: port config, connection status, side panel launcher
- Content script: floating ref panel with @ref badges
Conductor API proposal (docs/designs/CONDUCTOR_SESSION_API.md):
- SSE endpoint for full Claude Code session mirroring in Side Panel
- Discovery via HTTP endpoint (not filesystem — extensions can't read files)
TODOS.md: add $B watch, multi-agent tabs, cross-platform CDP, Web Store publishing.
Mark CDP mode as shipped.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: detect Conductor runtime, skip osascript quit for sandboxed apps
macOS App Management blocks Electron apps (Conductor) from quitting
other apps via osascript. Now detects the runtime environment:
- terminal/claude-code/codex: can manage apps freely
- conductor: prints manual restart instructions + polls for 60s
detectRuntime() checks env vars and parent process. When Chrome needs
restart but we can't quit it, prints step-by-step instructions and
waits for the user to restart Chrome with --remote-debugging-port.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: detect Conductor via actual env vars (CONDUCTOR_WORKSPACE_NAME)
Previous detection checked CONDUCTOR_WORKSPACE_ID which doesn't exist.
Conductor sets CONDUCTOR_WORKSPACE_NAME, CONDUCTOR_BIN_DIR, CONDUCTOR_PORT,
and __CFBundleIdentifier=com.conductor.app. Check these FIRST because
Conductor sessions also have ANTHROPIC_API_KEY (which was matching claude-code).

* feat: connection status pill — floating indicator when gstack controls Chrome
Small pill in bottom-right corner of every page: "● gstack · 3 refs"
Shows when connected via CDP, fades to 30% opacity after 3s, full on hover.
Disappears entirely when disconnected.
Background worker now notifies content scripts on connect/disconnect state
changes so the pill appears/disappears without polling.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: Chrome requires --user-data-dir for remote debugging
Chrome refuses --remote-debugging-port without an explicit --user-data-dir.
Add userDataDir to BrowserBinary registry (macOS Application Support paths)
and pass it in both auto-launch and manual restart instructions.
Fix double-quoting in CLI manual restart instructions.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: Chrome must be fully quit before launching with --remote-debugging-port
Chrome refuses to enable CDP on its default profile when another instance
is running (even with explicit --user-data-dir). The only reliable path:
fully quit Chrome first, then relaunch with the flag.
Updated instructions to emphasize this clearly with verification step.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: bin/chrome-cdp — quit Chrome and relaunch with CDP in one command
Quits Chrome gracefully, waits for full exit, relaunches with
--remote-debugging-port, polls until CDP is ready. Usage: chrome-cdp [port]
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: use Playwright channel:chrome instead of broken connectOverCDP
Playwright's connectOverCDP hangs with Chrome 146 due to CDP protocol
version mismatch. Switch to channel:'chrome' which uses Playwright's
native pipe protocol to launch the system Chrome binary directly.
This is simpler and more reliable:
- No CDP port discovery needed
- No --remote-debugging-port or --user-data-dir hassles
- $B connect just works — launches real Chrome headed window
- All Playwright APIs (snapshot, click, fill) work unchanged
bin/chrome-cdp updated with symlinked profile approach (kept for
manual CDP use cases, but $B connect no longer needs it).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: green border + gstack label on controlled Chrome window
Injects a 2px green border and small "gstack" label on every page
loaded in the controlled Chrome window via context.addInitScript().
Users can instantly tell which Chrome window Claude controls.
Also fixes close() for channel:chrome mode (uses browser.close()
not browser.disconnect() which doesn't exist).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* chore: cleanup chrome-launcher runtime detection, remove puppeteer-core dep
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* style(design): redesign controlled Chrome indicator
Replace crude green border + label with polished indicator:
- 2px shimmer gradient at top edge (green→cyan→green, 3s loop)
- Floating pill bottom-right with frosted glass bg, fades to 25%
opacity after 4s so it doesn't compete with page content
- prefers-reduced-motion disables shimmer animation
- Much more subtle — looks like a developer tool, not broken CSS

* docs: document real browser mode + Chrome extension in BROWSER.md and README.md
BROWSER.md: new sections for connect/disconnect/focus commands,
Chrome extension Side Panel install, CDP-aware skills, activity streaming.
Updated command reference table, key components, env vars, source map.
README.md: updated /browse description, added "Real browser mode" to
What's New section.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* docs: step-by-step Chrome extension install guide in BROWSER.md
Replace terse bullet points with numbered walkthrough covering:
developer mode toggle, load unpacked, macOS file picker tip (Cmd+Shift+G),
pin extension, configure port, open side panel. Added troubleshooting section.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* docs: add Cmd+Shift+. tip for hidden folders in macOS file picker
macOS hides folders starting with . by default. Added both shortcuts:
Cmd+Shift+G (paste path directly) and Cmd+Shift+. (show hidden files).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* docs: integrate hidden folder tips into the install flow naturally
Move Cmd+Shift+G and Cmd+Shift+. tips inline with the file picker
step instead of as a separate tip block after it.

* feat: auto-load Chrome extension when $B connect launches Chrome
Extension auto-loads via --load-extension flag — no manual chrome://extensions
install needed. findExtensionPath() checks repo root, global install, and dev
paths. Also adds bin/gstack-extension helper for manual install in regular
Chrome, and rewrites BROWSER.md install docs with auto-load as primary path.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: /connect-chrome skill — one command to launch Chrome with Side Panel
New skill that runs $B connect, verifies the connection, guides the user
to open the Side Panel, and demos the live activity feed. Extension auto-loads
via --load-extension so no manual chrome://extensions install needed.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: use launchPersistentContext for Chrome extension loading
Playwright's chromium.launch() silently ignores --load-extension.
Switch to launchPersistentContext with ignoreDefaultArgs to remove
--disable-extensions flag. Use bundled Chromium (real Chrome blocks
unpacked extensions). Fixed port 34567 for CDP mode so the extension
auto-connects.

* feat: sync extension to DESIGN.md — amber accent, zinc neutrals, grain texture
Import design system from gstack-website. Update all extension colors:
green (#4ade80) → amber (#F59E0B/#FBBF24), zinc gray neutrals, grain
texture overlay. Regenerate icons as amber "G" monogram on dark background.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: sidebar chat with Claude Code — icon opens side panel directly
Replace popup flyout with direct side panel open on icon click. Primary
UI is now a chat interface that sends messages to Claude Code via file
queue. Activity/Refs tabs moved behind a debug toggle in the footer.
Command bar with history, auto-poll for responses, amber design system.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: sidebar agent — Claude-powered chat backend via file queue
Add /sidebar-command, /sidebar-response, and /sidebar-chat endpoints
to the browse server. sidebar-agent.ts watches the command queue file,
spawns claude -p with browse context for each message, and streams
responses back to the sidebar chat.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: remove duplicate gstack pill overlay, hide crash restore bubble
The addInitScript indicator and the extension's content script were both
injecting bottom-right pills, causing duplicates. Remove the pill from
addInitScript (extension handles it). Replace --restore-last-session with
--hide-crash-restore-bubble to suppress the "Chromium didn't shut down
correctly" dialog.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: state file authority — CDP server cannot be silently replaced
Hardens the connect/disconnect lifecycle:
- ensureServer() refuses to auto-start headless when CDP server is alive
- $B connect does full cleanup: SIGTERM → 2s → SIGKILL, profile locks, state
- shutdown() cleans Chromium SingletonLock/Socket/Cookie files
- uncaughtException/unhandledRejection handlers do emergency cleanup
This prevents the bug where a headless server overwrites the CDP server's
state file, causing $B commands to hit the wrong browser.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: sidebar agent streaming events + session state management
Enhance sidebar-agent.ts with:
- Live streaming of claude -p events (tool_use, text, result) to sidebar
- Session state file for BROWSE_STATE_FILE propagation to claude subprocess
- Improved logging (stderr, exit codes, event types)
- stdin.end() to prevent claude waiting for input
- summarizeToolInput() with path shortening for compact sidebar display
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: sidebar chat UI — streaming events, agent status, reconnect retry
Sidebar panel improvements:
- Chat tab renders streaming agent events (tool_use, text, result)
- Thinking dots animation while agent processes
- Agent error display with styled error blocks
- tryConnect() with 2s retry loop for initial connection
- Debug tabs (Activity/Refs) hidden behind gear toggle
- Clear chat button
- Compact tool call display with path shortening
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: server-integrated sidebar agent with sessions and message queue
Move the sidebar agent from a separate bun process into server.ts:
- Agent spawns claude -p directly when messages arrive via /sidebar-command
- In-memory chat buffer backed by per-session chat.jsonl on disk
- Session manager: create, load, persist, list sessions
- Message queue (cap 5) with agent status tracking (idle/processing/hung)
- Stop/kill endpoints with queue dismiss support
- /health now returns agent status + session info
- All sidebar endpoints require Bearer auth
- Agent killed on server shutdown
- 120s timeout detects hung claude processes
Eliminates: file-queue polling, separate sidebar-agent.ts process,
stale auth tokens, state file conflicts between processes.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: extension auth + token flow for server-integrated agent
Update Chrome extension to use Bearer auth on all sidebar endpoints:
- background.js captures auth token from /health, exposes via getToken msg
- background.js sets openPanelOnActionClick for direct side panel access
- sidepanel.js gets token from background, sends in all fetch headers
- Health broadcasts include token so sidebar auto-authenticates
- Removes popup from manifest — icon click opens side panel directly
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: self-healing sidebar — reconnect banner, state machine, copy button
Sidebar UI now handles disconnection gracefully:
- Connection state machine: connected → reconnecting → dead
- Amber pulsing banner during reconnect (2s retry, 30 attempts)
- Red "Server offline" banner with Reconnect + Copy /connect-chrome buttons
- Green "Reconnected" toast that fades after 3s on successful reconnect
- Copy button lets user paste /connect-chrome into any Claude Code session
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: crash handling — save session, kill agent, distinct exit codes
Hardened shutdown/crash behavior:
- Browser disconnect exits with code 2 (distinct from crash code 1)
- emergencyCleanup kills agent subprocess and saves session state
- Clean shutdown saves session before exit (chat history persists)
- Clear user message on browser disconnect: "Run $B connect to reconnect"
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: worktree-per-session isolation for sidebar agent
Each sidebar session gets an isolated git worktree so the agent's file
operations don't conflict with the user's working directory:
- createWorktree() creates detached HEAD worktree in ~/.gstack/worktrees/
- Falls back to main cwd for non-git repos or on creation failure
- Handles collision cleanup from prior crashes
- removeWorktree() cleans up on session switch and shutdown
- worktreePath persisted in session.json
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(qa): ISSUE-001 — disconnect blocked by CDP guard in ensureServer
$B disconnect was routed through ensureServer() which refused to start a
headless server when a CDP state file existed. Disconnect is now handled
before ensureServer() (like connect), with force-kill + cleanup fallback
when the CDP server is unresponsive.

* fix: resolve claude binary path for daemon-spawned agent
The browse server runs as a daemon and may not inherit the user's shell
PATH. Add findClaudeBin() that checks ~/.local/bin/claude (standard
install location), which claude, and common system paths. Shows a clear
error in the sidebar chat if claude CLI is not found.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: resolve claude symlinks + check Conductor bundled binary
posix_spawn fails on symlinks in compiled bun binaries. Now:
- Checks Conductor app's bundled binary first (not a symlink)
- Scans ~/.local/share/claude/versions/ for direct versioned binaries
- Uses fs.realpathSync() to resolve symlinks before spawning
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: compiled bun binary cannot posix_spawn — use external agent process
Compiled bun binaries fail posix_spawn on ALL executables (even /bin/bash).
The server now writes to an agent queue file, and a separate non-compiled
bun process (sidebar-agent.ts) reads the queue, spawns claude, and POSTs
events back via /sidebar-agent/event.
Changes:
- server.ts: spawnClaude writes to queue file instead of spawning directly
- server.ts: new /sidebar-agent/event endpoint for agent → server relay
- server.ts: fix result event field name (event.text vs event.result)
- sidebar-agent.ts: rewritten to poll queue file, relay events via HTTP
- cli.ts: $B connect auto-starts sidebar-agent as non-compiled bun process
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: loading spinner on sidebar open while connecting to server
Shows an amber spinner with "Connecting..." when the sidebar first opens,
replacing the empty state. After the first successful /sidebar-chat poll:
- If chat history exists: renders it immediately
- If no history: shows the welcome message
Prevents the jarring empty-then-populated flash on sidebar open.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: zero-friction side panel — auto-open on install, pill is clickable
Three changes to eliminate manual side panel setup:
- Auto-open side panel on extension install/update (onInstalled listener)
- gstack pill (bottom-right) is now clickable — opens the side panel
- Pill has pointer-events: auto so clicks always register (was: none)
User no longer needs to find the puzzle piece icon, pin the extension,
or know the side panel exists. It opens automatically on first launch
and can be re-opened by clicking the floating gstack pill.

* refactor: kill CDP naming, delete chrome-launcher.ts dead code
The connectCDP() method and connectionMode: 'cdp' naming was a legacy
artifact — real Chrome was tried but failed (silently blocks
--load-extension), so the implementation already used Playwright's
bundled Chromium via launchPersistentContext(). The naming was
misleading.
Changes:
- Delete chrome-launcher.ts (361 LOC) — only import was in unreachable
attemptReconnect() method
- Delete dead attemptReconnect() and reconnecting field
- Delete preExistingTabIds (was for protecting real Chrome tabs we
never connect to)
- Rename connectCDP() → launchHeaded()
- Rename connectionMode: 'cdp' → 'headed' across all files
- Replace BROWSE_CDP_URL/BROWSE_CDP_PORT env vars with BROWSE_HEADED=1
- Regenerate SKILL.md files for updated command descriptions
- Move BrowserManager unit tests to browser-manager-unit.test.ts
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: converge handoff into connect — extension loads on handoff
Handoff now uses launchPersistentContext() with extension auto-loading,
same as the connect/launchHeaded() path. This means when the agent
gets stuck (2FA, CAPTCHA) and hands off to the user, the Chrome
extension + side panel are available automatically.
Before: handoff used chromium.launch() + newContext() — no extension
After: handoff uses chromium.launchPersistentContext() — extension loads
Also sets connectionMode to 'headed' and disables dialog auto-accept
on handoff, matching connect behavior.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: gate sidebar chat behind --chat flag
$B connect (default): headed Chromium + extension with Activity + Refs
tabs only. No separate agent spawned. Clean, no confusion.
$B connect --chat: same + Chat tab with standalone claude -p agent.
Shows experimental banner: "Standalone mode — this is a separate
agent from your workspace."
Implementation:
- cli.ts: parse --chat, set BROWSE_SIDEBAR_CHAT env, conditionally
spawn sidebar-agent
- server.ts: gate /sidebar-* routes behind chatEnabled, return 403
when disabled, include chatEnabled in /health response
- sidepanel.js: applyChatEnabled() hides/shows Chat tab + banner
- background.js: forward chatEnabled from health response
- sidepanel.html/css: experimental banner with amber styling
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: file drop relay + $B inbox command
Sidebar agent now writes structured messages to .context/sidebar-inbox/
when processing user input. The workspace agent can read these via
$B inbox to see what the user reported from the browser.
File drop format:
.context/sidebar-inbox/{timestamp}-observation.json
{ type, timestamp, page: {url}, userMessage, sidebarSessionId }
Atomic writes (tmp + rename) prevent partial reads. $B inbox --clear
removes messages after display.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: $B watch — passive observation mode
Claude enters read-only mode and captures periodic snapshots (every 5s)
while the user browses. Mutation commands (click, fill, etc.) are
blocked during watch. $B watch stop exits and returns a summary with
the last snapshot.
Requires headed mode ($B connect). This is the inverse of the scout
pattern — the workspace agent watches through the browser instead of
the sidebar relaying to it.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test: add coverage for sidebar-agent, file-drop, and watch mode
33 new tests covering:
- Sidebar agent queue parsing (valid/malformed/empty JSONL)
- writeToInbox file drop (directory creation, atomic writes, JSON format)
- Inbox command (display, sorting, --clear, malformed file handling)
- Watch mode state machine (start/stop cycles, snapshots, duration)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* docs: TODOS cleanup + Chrome vs Chromium exploration doc
- Update TODOS.md: mark CDP mode, $B watch, sidebar scout as SHIPPED
- Delete dead "cross-platform CDP browser discovery" TODO
- Rename dependencies from "CDP connect" to "headed mode"
- Add docs/designs/CHROME_VS_CHROMIUM_EXPLORATION.md memorializing
the architecture exploration and decision to use Playwright Chromium
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* docs: add Conductor Chrome sidebar integration design doc
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: sidebar-agent validates cwd before spawning claude
The queue entry may reference a worktree that was cleaned up between
sessions. Now falls back to process.cwd() if the path doesn't exist,
preventing silent spawn failures.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: gen-skill-docs resolver merge + preamble tier gate + plan file discovery
The local RESOLVERS record in gen-skill-docs.ts was shadowing the imported
canonical resolvers, causing stale test coverage and preamble generators
to be used instead of the authoritative versions in resolvers/.
Changes:
- Merge imported RESOLVERS with local overrides (spread + override pattern)
- Fix preamble tier gate: tier 1 skills no longer get AskUserQuestion format
- Make plan file discovery host-agnostic (search multiple plan dirs)
- Add missing E2E tier entries for ship/review plan completion tests
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: ungate sidebar agent + raise timeout to 5 minutes (v0.12.0)
Sidebar chat is now always available in headed mode — no --chat flag needed.
Agent tasks get 5 minutes instead of 2, enabling multi-page workflows like
navigating directories and filling forms across pages.
Changes:
- cli.ts: remove --chat flag, always set BROWSE_SIDEBAR_CHAT=1, always spawn agent
- server.ts: remove chatEnabled gate (403 response), raise AGENT_TIMEOUT_MS to 300s
- sidebar-agent.ts: raise child process timeout from 120s to 300s
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* docs: headed mode + sidebar agent documentation (v0.12.0)
- README: sidebar agent section, personal automation example (school parent
portal), two auth paths (manual login + cookie import), DevTools MCP mention
- BROWSER.md: sidebar agent section with usage, timeout, session isolation,
authentication, and random delay documentation
- connect-chrome template: add sidebar chat onboarding step
- CHANGELOG: v0.12.0 entry covering headed mode, sidebar agent, extension
- VERSION: bump to 0.12.0.0
- TODOS: Chrome DevTools MCP integration as P0

* chore: regenerate SKILL.md files
Generated from updated templates + resolver merge. Key changes:
- Tier 1 skills no longer include AskUserQuestion format section
- Ship/review skills now include coverage gate with thresholds
- Connect-chrome skill includes sidebar chat onboarding step
- Plan file discovery uses host-agnostic paths
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* chore: regenerate Codex connect-chrome skill
Updated preamble with proactive prompt and sidebar chat onboarding step.

* feat: network idle, state persistence, iframe support, chain pipe format (v0.12.1.0) (#516)
* feat: network idle detection + chain pipe format
- Upgrade click/fill/select from domcontentloaded to networkidle wait
(2s timeout, best-effort). Catches XHR/fetch triggered by interactions.
- Add pipe-delimited format to chain as JSON fallback:
$B chain 'goto url | click @e5 | snapshot -ic'
- Add post-loop networkidle wait in chain when last command was a write.
- Frame-aware: commands use target (getActiveFrameOrPage) for locator ops,
page-only ops (goto/back/forward/reload) guard against frame context.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: $B state save/load + $B frame — new browse commands
- state save/load: persist cookies + URLs to .gstack/browse-states/{name}.json
File perms 0o600, name sanitized to [a-zA-Z0-9_-]. V1 skips localStorage
(breaks on load-before-navigate). Load replaces session via closeAllPages().
- frame: switch command context to iframe via CSS selector, @ref, --name, or
--url. 'frame main' returns to main frame. Execution target abstraction
(getActiveFrameOrPage) across read-commands, snapshot, and write-commands.
- Frame context cleared on tab switch, navigation, resume, and handoff.
- Snapshot shows [Context: iframe src="..."] header when in frame.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test: add tests for network idle, chain pipe format, state, and frame
- Network idle: click on fetch button waits for XHR, static click is fast
- Chain pipe: pipe-delimited commands, quoted args, JSON still works
- State: save/load round-trip, name sanitization, missing state error
- Frame: switch to iframe + back, snapshot context header, fill in frame,
goto-in-frame guard, usage error
New fixtures: network-idle.html (fetch + static buttons), iframe.html (srcdoc)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: review fixes — iframe ref scoping, detached frame recovery, state validation
- snapshot.ts: ref locators, cursor-interactive scan, and cursor locator
now use target (frame-aware) instead of page — fixes @ref clicking in iframes
- browser-manager.ts: getActiveFrameOrPage auto-recovers from detached frames
via isDetached() check
- meta-commands.ts: state load resets activeFrame, elementHandle disposed after
contentFrame(), state file schema validation (cookies + pages arrays),
filter empty pipe segments in chain tokenizer
- write-commands.ts: upload command uses target.locator() for frame support
