v1.58.1.0 feat: hermetic local E2E + Conductor prose AskUserQuestion (#2004)
* feat: add shared call-time isConductor() helper
Single source of truth for Conductor host detection in TS consumers
(CONDUCTOR_WORKSPACE_PATH / CONDUCTOR_PORT). Reads the passed env at
call time, not a module-load snapshot, so unit tests can pin the env
inline without Bun --preload (esm-hoist-breaks-env-pin-bootstrap).
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* test: harden question-preference-hook harness against ambient Conductor env
runHook copied all of process.env into the hook subprocess, so running the
suite inside Conductor (CONDUCTOR_WORKSPACE_PATH/PORT set) would leak those
markers. Strip them so the existing cases deterministically characterize
NON-Conductor behavior before the Conductor branch lands. Baseline: 15 pass.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* feat: PreToolUse hook denies AskUserQuestion in Conductor, redirects to prose
Conductor disables native AskUserQuestion and routes through a flaky MCP
variant that returns '[Tool result missing due to internal error]'. The
hook now denies any AUQ call in a Conductor session and instructs the model
to render a prose decision brief instead (transport avoidance, not preference
enforcement) — firing for one-way doors too, with a typed-confirmation
requirement for destructive paths.
Precedence: never-ask auto-decide still wins (user already settled those);
Conductor prose is the fallback for everything else; non-Conductor behavior
is byte-for-byte unchanged. Restructured the per-question loop to compute
eligibility without early-returning so the Conductor branch can run as the
fallback while preserving memoryContext on every exit.

* feat: Conductor renders AskUserQuestion decisions as prose by default
In Conductor, native AskUserQuestion is disabled and the MCP variant is
flaky, so skills now render every decision as a plain-text prose brief the
user answers by typing a letter — proactively, not as a failure reaction.
- Preamble emits CONDUCTOR_SESSION, gated on != headless so eval/CI inside
Conductor still BLOCKs instead of rendering prose to nobody.
- AskUserQuestion Format gains a Conductor-default-prose rule (auto-decide
preferences still apply first; prose decisions log via gstack-question-log
since PostToolUse never fires), a one-way/destructive typed-confirmation
rule, and a typed-reply continuation protocol for split chains.
- Regenerated all SKILL.md + ship golden fixtures; bumped affected carve
skeleton caps to absorb the always-loaded additions.

* feat: deploy the Conductor AskUserQuestion hook (setup + upgrade migration)
The PreToolUse hook only delivers its Conductor-prose guarantee if it's
installed, but setup skips hook registration in non-interactive (conductor/CI)
setups. Two fixes so layer 3 actually deploys:
- setup: treat a Conductor workspace as an implicit opt-in for the PreToolUse
hook on the silent fall-through (never overriding an explicit opt-out).
- migration v1.58.0.0: re-register the hook for existing Conductor installs on
/gstack-upgrade, idempotent and respecting plan_tune_hooks=no.

* test: E2E for Conductor prose + fix auto-decide-preserved GSTACK_HOME bug
- New skill-e2e-conductor-prose (periodic): Conductor env + plan-eng-review
surfaces a prose decision brief, not a silent skip. Header documents this is
end-to-end behavior coverage; the deterministic Conductor guard is the
question-preference-hook unit test (the PTY harness can't register the MCP
variant — Codex #10).
- Fix the pre-existing bug in auto-decide-preserved: it seeded the never-ask
preference under GSTACK_HOME=tmpHome but never passed GSTACK_HOME into the
PTY run, so the spawned claude read the real ~/.gstack and the preference
was inert (Codex #9). Now passes GSTACK_HOME + CONDUCTOR_WORKSPACE_PATH to
prove auto-decide still wins over the Conductor prose redirect.
- Register both in touchfiles (periodic tier).

* v1.58.0.0 feat: Conductor renders AskUserQuestion decisions as prose
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* test: strip ambient Conductor env in memory-cache-injection hook harness
Same dev-in-Conductor leak fixed for question-preference-hook: this suite's
runHook copies process.env, so running it inside Conductor flipped the
defer-path memoryContext assertions into the [conductor] prose deny. Strip
CONDUCTOR_* so the cases characterize non-Conductor behavior. (CI is headless,
so this only bit local Conductor runs.)

* feat: gstack-detach — run agent eval/bench jobs in their own session
Long agent-run jobs (30-60 min evals, benchmarks) die when the harness sends
SIGTERM to a background task's process group on turn boundaries / monitor
stops / interruptions (observed: 'script test:gate terminated by signal
SIGTERM'). gstack-detach runs the command in a fresh session (python3
os.setsid, or setsid on Linux, nohup fallback) so a group SIGTERM can't reach
it, and wraps it in caffeinate -i on macOS so idle-sleep can't kill it either.
Returns immediately; caller polls the logfile. Secrets stay in env, never argv.
The guard test pins the contract: the command runs in a different process
group than the caller and outlives the launching shell.

* feat: eval:bg* scripts — detached eval runs for agents
Agent-facing convenience scripts that launch the eval suites through
gstack-detach so a harness SIGTERM can't kill a long run. eval:bg (diff-based),
eval:bg:all, eval:bg:gate, eval:bg:periodic — each returns immediately and
streams to /tmp/gstack-evals.log for polling. The plain test:evals / test:e2e
scripts stay foreground for humans.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* docs: CLAUDE.md — agents must run long evals via gstack-detach
Codifies the detached-execution default: agent-launched eval/benchmark runs go
through bin/gstack-detach (or the eval:bg* scripts) so a harness SIGTERM or
macOS idle-sleep can't kill a 30-60 min run, then poll the log with a
death-aware watcher. Humans keep foreground scripts.

* feat: harden gstack-detach against all four eval-infra killers
The basic bash detach fixed SIGTERM but a real run on a shared dev box hit
three more killers: cross-worktree API saturation (15-way concurrency x a
sibling worktree mass-timed-out the suite), a silent hang (periodic bun died
with no exit marker), and shared-/tmp log contamination (a concurrent
worktree's agent output bled into the log). Rewrite as a portable python3 tool
that bakes in all four fixes:
- fork + setsid: SIGTERM-proof (own session, survives harness polite-quit)
- caffeinate -i on macOS: no idle-sleep death
- --lock NAME (fcntl, machine-wide): concurrent worktrees SERIALIZE instead of
saturating the shared model API
- run-scoped default log (~/.gstack-dev/eval-runs/<label>-<slug>-<branch>-<ts>-<pid>):
no cross-worktree collision/contamination
- --timeout watchdog + a guaranteed '### gstack-detach EXIT=<code> ###' sentinel
on every terminal path: no silent hang, finished-vs-died always detectable
Guard test pins all four: detached pgid differs + outlives launcher, run-scoped
log path, watchdog EXIT=timeout, and lock serialization (second run WAITS).
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* feat: eval:bg* use run-scoped logs + machine lock + watchdog
Drop the shared /tmp/gstack-evals.log path (the cross-worktree collision that
contaminated a live run) for gstack-detach's run-scoped default, and add the
machine-wide gstack-evals lock (concurrent worktrees serialize, no API
saturation) plus per-tier watchdog timeouts (60/90/120 min). Each eval:bg*
prints its run-scoped log path to poll.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* docs: wire detached-eval guidance into /ship + correct CLAUDE.md flags
- /ship eval step (sections/tests.md): long eval suites launch via gstack-detach
(own session, machine lock, EXIT sentinel) so a turn boundary can't kill a
30+ min run mid-ship — the exact failure observed during this branch's ship.
- CLAUDE.md: correct the now-stale /tmp reference; document the --lock (serialize
worktrees, no API saturation), --timeout watchdog, run-scoped log, and the
guaranteed EXIT sentinel the poller breaks on.

* refactor: extract pure promotedEnv() from conductor-env-shim
Single source of truth for GSTACK_* key promotion semantics. The ambient
promoteConductorEnv() becomes a wrapper; behavior-preserving. Needed by the
hermetic env builder which must not mutate process.env.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* feat: hermetic child-env builder for E2E runners
Allowlist scrub (basics/network/named-auth kept; CONDUCTOR_*, CLAUDE_*,
GSTACK_*, MCP_*, GBRAIN_*, operator credentials dropped), per-runner
extraAllow, overrides merge last, EVALS_HERMETIC=0 byte-identical escape
hatch read at call time (ESM-hoist safe). Sync memoized singleton temp dirs
(<runRoot>/.claude keeps the extractPlanFilePath contract), seeded
.claude.json for non-interactive first run, pid-aware GC of crashed runs.
19 free unit tests.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* feat: session-runner spawns hermetic children + isolation canaries
claude -p children now get the allowlist-scrubbed env and a gated
--strict-mcp-config (EVALS_HERMETIC=0 restores operator env AND args).
Two gate-tier canaries make the clean room falsifiable: hermetic-canary
asserts env redirect + scrub + zero MCP servers + nonzero API-key cost
from the Bash tool_result (never model prose); hermetic-sentinel plants a
poisoned operator config (user CLAUDE.md + MCP server) and proves the
child cannot see it. Empirically verified on claude 2.1.175: print mode
needs no seed config (the seed serves the PTY path); the child CLI sets
CLAUDECODE for its own tools, so that scrub is pinned in unit tests, not
E2E. hermetic-env.ts joins GLOBAL_TOUCHFILES.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* feat: PTY runner spawns hermetic claude sessions
launchClaudePty children get the allowlist-scrubbed env, a gated
--strict-mcp-config, and the session exposes hermeticConfigDir for
forensics (hermetic plan files live under <dir>/plans/ and still match
extractPlanFilePath via the /.claude dir-name contract). Seeded trust
state covers repo-cwd sessions; the 15s trust-watcher stays as fallback.
Verified foreground via the plan-mode-no-op gate test.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* feat: codex/gemini runners spawn hermetic children
Same allowlist scrub as the claude runners, with each provider's auth
surface re-admitted via extraAllow (codex: OPENAI_API_KEY/CODEX_* plus
its tempHome .codex copy; gemini: GEMINI_*/GOOGLE_* with real HOME for
~/.gemini auth). The gemini spawn previously inherited the full operator
env with no env property at all.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* feat: agent-sdk-runner spawns hermetic children via complete Options.env
The historical 'env: breaks SDK auth' failure was partial-env replacement:
Options.env replaces the child's entire environment, so objects lacking
ANTHROPIC_API_KEY killed auth. Passing the complete hermetic env (key +
PATH + redirected CLAUDE_CONFIG_DIR/GSTACK_HOME) works — validated live
via query() with a Bash tool call (success, real cost, Conductor vars
scrubbed). Per-test opts.env merges last; ambient key mutation still
works because the builder reads process.env at call time.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* test: static tripwire pins hermetic wiring in all five runners
Free-tier invariants: every runner builds child env via hermeticChildEnv,
no raw ...process.env spread at any spawn site, --strict-mcp-config gated
on isHermeticEnabled in both claude runners, and no test callsite passes
the operator env into a runner's override parameter (scoped to runner
calls — unit tests spawning gstack bin scripts directly are exempt).
Mirrors the terminal-agent-pid-identity / server-embedder-terminal-port
tripwire idiom.

v1.11.1.0 fix: plan-mode handshake + canUseTool test harness (#1182)
* feat: plan-mode handshake for interactive review skills Add a preamble-level STOP-Ask handshake that fires when the user invokes any of the 4 interactive review skills (plan-ceo-review, plan-eng-review, plan-design-review, plan-devex-review) while their Claude Code session is in plan mode. Without this gate, plan mode's "this supercedes any other instructions" system-reminder outranked the skills' interactive STOP gates and the skills silently wrote plan files without any per-finding AskUserQuestion. The handshake offers 2 options (exit-and-rerun, cancel) — the original third "stay and batch" option was dropped after two independent reviewers flagged it as a silent bypass of the skills' anti-skip rule. Architecture decisions (CEO+Eng review): - Preamble-level resolver, not per-template injection (Codex finding #2) - Position 1 in preamble composition: after bash block (_SESSION_ID live), before onboarding AskUserQuestion gates (so fresh-install users see the handshake first, not drowned in telemetry/proactive/routing prompts) - Generator-only `interactive: true` frontmatter flag, following the `preamble-tier` precedent (no host-config frontmatter allowlist edits) - Host-scoped to Claude via `ctx.host === 'claude'` check inside the resolver (simpler than `suppressedResolvers` which only gates `{{}}` placeholders) - One-way-door classification in scripts/question-registry.ts for all 4 skills so question-tuning `never-ask` preferences can't suppress the gate - Synchronous telemetry write to ~/.gstack/analytics/skill-usage.jsonl on handshake fire (captures A-exit and C-cancel outcomes that terminate the skill before end-of-run telemetry runs) Also adds an explicit STOP block to plan-ceo-review Step 0C-bis so the approach-selection question can't silently skip to mode selection. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * feat: extend agent-sdk-runner with canUseTool for AskUserQuestion interception Test harness at test/helpers/agent-sdk-runner.ts gains an optional `canUseTool` callback parameter. When a test supplies it, the harness flips `permissionMode` from `bypassPermissions` (overlay-harness default) to `default` so the SDK actually invokes the callback on every tool use, and auto-adds `AskUserQuestion` to `allowedTools` so Claude can fire it at all. Exports a `passThroughNonAskUserQuestion` helper so tests that only want to intercept AskUserQuestion can auto-allow every other tool with one line: `return passThroughNonAskUserQuestion(toolName, input)`. This is the foundation for D14 — every future interactive-skill E2E test can now assert on AskUserQuestion shape and routing. Previous E2E tests at `test/skill-e2e.test.ts` explicitly instructed the model to skip AskUserQuestion ("non-interactive run") which meant no test could actually verify the question content or routing. 6 new unit tests in test/agent-sdk-runner.test.ts cover: - permissionMode flips to 'default' when canUseTool supplied - permissionMode stays 'bypassPermissions' when canUseTool absent - canUseTool callback reaches the SDK options - AskUserQuestion auto-added to allowedTools when canUseTool supplied - AskUserQuestion NOT added when canUseTool absent - passThroughNonAskUserQuestion helper returns allow+updatedInput Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * test: plan-mode handshake E2E coverage and unit assertions Adds 6 E2E test files and 8 new unit assertions to verify the plan-mode handshake works end-to-end and stays correct under regeneration. E2E tests (gate-tier, paid, EVALS=1 EVALS_TIER=gate): - test/skill-e2e-plan-ceo-plan-mode.test.ts — handshake fires before any Write/Edit when plan-mode distinctive phrase is present; 2-option shape (Exit/Cancel); option A routes to ExitPlanMode cleanly - test/skill-e2e-plan-eng-plan-mode.test.ts — same contract for plan-eng - test/skill-e2e-plan-design-plan-mode.test.ts — same contract for plan-design; exercises C-cancel branch instead of A-exit - test/skill-e2e-plan-devex-plan-mode.test.ts — same contract for plan-devex - test/skill-e2e-plan-mode-no-op.test.ts — negative regression: handshake must NOT fire when distinctive phrase is absent; skill proceeds normally through Step 0 (REGRESSION RULE guardrail against breaking existing interactive-review sessions) - test/e2e-harness-audit.test.ts — free unit test asserting every `interactive: true` skill has at least one canUseTool-using test file (prevents future drift where a skill opts in without coverage) Shared helper test/helpers/plan-mode-handshake-helpers.ts centralizes the canUseTool interceptor + distinctive-phrase injection so the 4 sibling E2E tests are thin wiring (~20 LOC each) and can't drift out of sync. Unit assertions added to test/gen-skill-docs.test.ts: - handshake section present in all 4 Claude-generated SKILL.md files - handshake section absent from non-interactive Claude skills (ship, review, qa, office-hours, codex, retro, cso) - handshake section absent from non-Claude host outputs (.agents, etc.) - 0C-bis STOP block present in plan-ceo-review/SKILL.md at correct position (between the "Present these approach options" line and "### 0D-prelude" header) - handshake resolver wired BEFORE generateUpgradeCheck in preamble composition order 6 new gate-tier entries added to test/helpers/touchfiles.ts so any change to the handshake resolver, preamble composition, skill templates, question registry, one-way-door classifier, or agent-sdk-runner fires the relevant E2E tests. test/touchfiles.test.ts updated for the new selection count (plan-ceo-review/** now triggers 15 tests, up from 8). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * chore(v1.11.1.0): VERSION bump + CHANGELOG entry + TODOS follow-ups Bumps from main's v1.11.0.0 to v1.11.1.0 (PATCH — bug-fix release, no new user-facing artifacts). CHANGELOG entry covers the plan-mode handshake, agent-sdk-runner canUseTool extension, and the 2 follow-up TODOs. CHANGELOG order: v1.11.1.0 (this) → v1.11.0.0 (workspace-aware ship, merged from main) → v1.10.1.0 (overlay efficacy harness). No duplicate headers. Syncs package.json version to match VERSION per the Step 12 idempotency invariant (both files must agree or /ship halts). TODOS.md: - Preserves the Testing/security-bench-haiku-responses P1 added on main - Adds P1 "Structural STOP-Ask forcing function" — broader class of the bug this release fixes - Adds P2 "Apply interactive: true to non-review skills (office-hours, codex, investigate, qa, retro, cso)" Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.7 <noreply@anthropic.com> |

feat(v1.10.1.0): overlay efficacy harness + Opus 4.7 fanout nudge removal (#1166)
* refactor: export readOverlay from model-overlay resolver Needed by the overlay-efficacy eval harness to resolve INHERIT directives without going through generateModelOverlay's full TemplateContext. * chore: add @anthropic-ai/claude-agent-sdk@0.2.117 dep Pinned exact for SDK event-shape stability. Used by the overlay-efficacy harness to drive the model through a closer-to-real Claude Code harness than `claude -p`. * feat(preflight): sanity check for agent-sdk + overlay resolver Verifies: SDK loads, claude-opus-4-7 is a live API model, SDKMessage event shape matches assumptions, readOverlay resolves INHERIT directives and includes expected content. Run with `bun run scripts/preflight-agent-sdk.ts`. PREFLIGHT OK on first run, $0.013 API spend. * feat(eval): parametric overlay-efficacy harness (runner + fixtures) `test/helpers/agent-sdk-runner.ts` wraps @anthropic-ai/claude-agent-sdk with explicit `AgentSdkResult` types, process-level API concurrency semaphore, and 3-shape 429 retry (thrown error, result-message error, mid-stream SDKRateLimitEvent). Pins the local claude binary via `pathToClaudeCodeExecutable`. `test/fixtures/overlay-nudges.ts` holds the typed registry. Two fixtures for the first measurement: `opus-4-7-fanout-toy` (3-file read) and `opus-4-7-fanout-realistic` (mixed-tool audit). Strict validator rejects duplicate ids, non-integer trials, unsafe overlay paths, non-safe id chars, and missing overlay files at module load. Adding a future overlay nudge eval = one fixture entry. * test(eval): unit tests for agent-sdk-runner (36 tests, free tier) Stub `queryProvider` feeds hand-crafted SDKMessage streams. Covers: happy-path shape, all 3 rate-limit shapes + retry, workspace reset on retry, persistent 429 -> `RateLimitExhaustedError`, non-429 propagation, process-level concurrency cap, options propagation, artifact path uniqueness, cost/turn mapping, and every validator rejection case. * test(eval): paid periodic overlay-efficacy harness `test/skill-e2e-overlay-harness.test.ts` iterates OVERLAY_FIXTURES, runs two arms per fixture (overlay-ON, overlay-OFF) at N=10 trials with bounded concurrency. Arms use SDK preset `claude_code` so both include the real Claude Code system prompt; overlay-ON appends the resolved overlay text. Saves per-trial raw event streams to `~/.gstack/projects/<slug>/transcripts/` for forensic recovery. Gated on `EVALS=1 && EVALS_TIER=periodic`. ~$3/run (40 trials). * test: register overlay harness in touchfiles (both maps) Entries for `overlay-harness-opus-4-7-fanout-toy` and `opus-4-7-fanout-realistic` in E2E_TOUCHFILES (deps: model-overlays/, fixtures file, runner, resolver) and E2E_TIERS (`periodic`). Passes `test/touchfiles.test.ts` completeness check. * fix(opus-4.7): remove "Fan out explicitly" overlay nudge Measured counterproductive under the new SDK harness. Baseline Opus 4.7 emits first-turn parallel tool_use blocks 70% of the time on a 3-file read prompt. With the custom nudge: 10%. With Anthropic's own canonical `<use_parallel_tool_calls>` block from their parallel-tool-use docs: 0%. Both overlays suppress fanout; neither improves it. On realistic multi-tool prompts (audit a project: read files + glob + summarize), Opus 4.7 never fans out in first turn regardless of overlay. Zero of 20 trials. Not a prompt problem. Keeping the other three nudges (effort-match, batch questions, literal interpretation) pending their own measurement. Harness is ready for follow-up fixtures — add one entry to `test/fixtures/overlay-nudges.ts` to measure any overlay bullet. Cost of investigation: ~$7 total across 3 eval runs. * chore: bump version and changelog (v1.6.5.0) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(eval): extend OverlayFixture with allowedTools, maxTurns, direction Per-fixture tool allowlist unblocks measuring nudges that need Edit/Write (e.g. literal-interpretation 'fix the failing tests' needs write access). Per-fixture maxTurns lets harder prompts run longer without changing the default. `direction` is cosmetic metadata for test output labeling. Also adds reusable predicates and metrics: - lowerIsBetter20Pct / higherIsBetter20Pct — 20% lift threshold vs baseline - bashToolCallCount — count of Bash tool_use across the session - turnsToCompletion — SDK-reported num_turns at result - uniqueFilesEdited — Edit/Write/MultiEdit file_path set size test/skill-e2e-overlay-harness.test.ts now threads fixture.allowedTools and fixture.maxTurns through runArm. * test(eval): 3 more overlay fixtures to measure remaining Claude nudges Measures three overlay bullets that haven't been tested yet: - claude-dedicated-tools-vs-bash — claude.md says 'prefer Read/Edit/Write/ Glob/Grep over cat/sed/find/grep'. Fixture prompts 'list every TypeScript file under src/ and tell me what each exports' and counts Bash tool_use across the session. Overlay-ON should drop it by >=20%. - opus-4-7-effort-match-trivial — opus-4-7.md says 'simple file reads don't need deep reasoning.' Fixture uses a trivial one-file prompt (config.json lookup) and measures turns_used. Overlay-ON should be <=80% of baseline turns. - opus-4-7-literal-interpretation — opus-4-7.md says 'fix ALL failing tests, not just the obvious one.' Fixture seeds three failing test files with deliberately distinct failure modes and counts unique files edited. Overlay-ON should touch >=20% more files. Adding a fourth fixture for any remaining overlay nudge is a single entry. The harness is now proven on: fanout (deleted after measurement), dedicated tools, effort-match, and literal-interpretation. * fix(eval): handle SDK max-turns throw gracefully Some @anthropic-ai/claude-agent-sdk versions throw from the query generator when maxTurns is reached, instead of emitting a result message with subtype='error_max_turns'. The runner treated that as a non-retryable error and killed the whole periodic run on the first fixture that exceeded its turn cap. Added isMaxTurnsError() detector and a catch branch that synthesizes an AgentSdkResult from events captured before the throw, with exitReason='error_max_turns' and costUsd=0 (unknown from the thrown path). The metric function still runs against whatever assistant turns were collected, so the trial produces a usable number. Hoisted events/assistantTurns/toolCalls/assistantTextParts and the timing counters out of the inner try so the catch branch can read them. No behavior change on the success path or on rate-limit retry paths. * test(eval): bump maxTurns to 15 for claude-dedicated-tools-vs-bash The prompt 'list every TypeScript file under src/ and tell me what each exports' needs 1 turn for Glob + ~5 for Reads + 1 for summary. Default maxTurns=5 was not enough; prior run threw from the SDK on this fixture and tanked the whole periodic eval. Bumping to 15 gives headroom. The runner now also handles max-turns gracefully even if a future fixture underestimates, so this is belt and suspenders. * test(eval): Sonnet 4.6 variants of the 5 Opus-4.7 fixtures Same overlays, same prompts, same metrics, `model: 'claude-sonnet-4-6'`. Tests whether the overlays behave differently on a weaker Claude model where baseline behavior is shakier. Sonnet trials cost ~3-4x less than Opus so these 5 add ~$4.50 to a full run. Measurement result from the first paired run (100 trials total, ~$14.55): - **Sonnet + effort-match shows real overlay benefit.** With the overlay on, Sonnet takes 2.5 turns on a trivial `What's the version in config.json?` prompt. Without, it takes exactly 3.0 turns in all 10 trials. ~17% reduction, below the 20% pass threshold but the signal is clean: overlay-ON distribution [2,2,2,2,2,3,3,3,3,3] vs overlay-OFF [3,3,3,3,3,3,3,3,3,3]. - All other Sonnet dimensions flat (fanout, dedicated-tools, literal interpretation). Same as Opus on those axes. - Opus effort-match remains flat (2.60 vs 2.50, +4% slower with overlay). Implication: model-stratified. The overlay stack helps Sonnet on some axes where it does nothing on Opus. Wholesale removal would hurt Sonnet. Per-nudge per-model measurement is the right move going forward. * chore: bump version to 1.10.1.0 Updates VERSION, package.json, CHANGELOG header, and TODOS completion marker from 1.6.5.0 to 1.10.1.0. --------- Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |
