## Linked Issues or Issue Description
**What existing behavior does this improve?**
This change improves work-product presentation in task threads and the
task Artifacts tab.
**Subsystem affected**
The change affects shared work-product contracts, the runner diff path,
server attachment and work-product services, GitHub metadata refresh,
the React board UI, and Storybook.
**Current behavior**
The thread used generic cards. Some files uploaded by a run existed only
as message attachments. The Artifacts tab showed a flat list without run
context or filters. Storybook showed only one resting card per kind.
**Proposed behavior**
The thread uses rich cards for supported work-product types. Each
run-produced file registers one attachment-backed artifact work product.
The Artifacts tab groups outputs by run and supports filters. Storybook
shows every kind and requested state, PR lifecycle states, stats
variants, truncation, mobile layout, and message-tail media.
**Reason and benefit**
Users can identify outputs quickly. Reviewers can inspect all card
permutations without creating task data.
**Breaking changes**
None. The metadata fields and automatic artifact registration are
additive. Existing attachments and work products keep their current
behavior.
## What Changed
- Added a shared rich work-product card with kind-specific content and a
compact inventory variant.
- Added pull-request and commit diff metadata plus bounded GitHub state
refresh.
- Added media strips and typed file chips to message-tail attachments.
- Registered each run-produced attachment as an artifact work product in
the same server transaction.
- Grouped task artifacts by run with agent and timestamp headings.
- Added type and run filters, image thumbnails, compact cards, and a
company Artifacts link.
- Added a Storybook kind-by-state matrix with stats variants for all
eight visual kinds.
- Added PR open, draft, merged, and closed examples, long-title
truncation, an exact 375-pixel viewport, and message-tail overflow
coverage.
- Closed reconciled runtime work products when the linked runtime stops
or disappears, so the card shows `Stopped` instead of `Unhealthy`.
### Screenshots
Before: one resting card per kind.
After: the kind and state matrix.
After: message-tail media at 375 pixels.

## Verification
- `pnpm --filter @paperclipai/ui typecheck` passed.
- `pnpm check:token-gates` passed.
- `pnpm build-storybook` passed.
- `pnpm exec vitest run
server/src/__tests__/work-product-runtime-reconciliation.test.ts` passed
with 5 tests.
- Chromium visual checks passed at desktop and 375-pixel widths.
- All 30 latest-head GitHub checks passed. One unrelated annotation test
was flaky and passed on its single retry.
- Greptile passed at 5/5 with zero unresolved threads.
## Risks
- Low risk. The Storybook change adds review fixtures only. The runtime
fix changes read-time reconciliation without database writes.
- The matrix is intentionally large so every permutation stays visible
in one review surface.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The task detail page uses a chat-style thread with a right sidebar;
the sidebar has a Plan tab and an Artifacts tab (#11101 made this UI the
default)
> - The Plan tab only showed the one issue document named `plan`, and
the Artifacts tab only listed formal work products; other agent-authored
documents (for example a `synthesis` doc) and agent-attached files were
invisible in the sidebar
> - Users could see an agent mention a document in the thread but had no
way to find that document in the sidebar, which breaks trust in the task
view as the record of the work
> - This pull request surfaces every non-system issue document in the
Plan tab, composes the Artifacts tab from work products, documents, and
agent-created attachments, and gives thread images a full-screen
lightbox with download
> - The benefit is that anything an agent produces on a task is now
reachable from the sidebar, while user uploads stay with their comments
in the thread
## Linked Issues or Issue Description
Refs #11101 (chat-style task UI default — this PR extends its sidebar).
**Subsystem affected**
Task detail UI (chat-style thread sidebar): Plan tab, Artifacts tab, and
thread attachment rendering in `ui/src`.
**Current behavior**
The Plan tab renders only the issue document literally named `plan`. The
Artifacts tab renders only formal work products. Agent-authored
documents with any other name, and files agents attach to comments, do
not appear anywhere in the sidebar. Thread images open as bare links.
**Proposed behavior**
The Plan tab lists every non-system issue document, with the `plan`
document first and the others rendered inline below it. The Artifacts
tab composes three sources — work products, issue documents, and
agent-created comment attachments — deduplicated against
attachment-backed work products via `metadata.attachmentId`, and shows
whenever any source is non-empty. Work-product rows without a resolvable
attachment or document fall back to links found in their metadata so
they stay clickable. Images in the thread open a shared full-screen
lightbox with a download action. Files uploaded by users stay
thread-only and are not mixed into the Artifacts tab.
**Reason and benefit**
Agents routinely produce documents that are not named `plan` and attach
files to their comments. Users reading the thread must be able to find
every one of those outputs from the sidebar. Redundant surfacing is
acceptable; an unfindable document is not.
**Breaking changes**
None. This is additive rendering; no schema or API changes.
## What Changed
- `IssuePropertiesPlansTab.tsx`: renders all non-system issue documents,
`plan` primary, others inline below via `MarkdownBody`
- `IssuePropertiesArtifactsTab.tsx`: composes work products + documents
+ agent-created attachments with dedupe; rows without an
attachment/document target fall back to `metadata` links
- `IssueProperties.tsx`: Artifacts tab visibility now derives from the
composed source set
- New `ui/src/lib/issue-artifacts.ts`: pure composition/dedupe logic,
unit-tested
- New `ui/src/components/task-chat/task-chat-attachments.ts`: splits
agent vs user comment attachments, unit-tested
- `TaskChatBubble.tsx`: thread images open the shared full-screen
lightbox with download
- `useIssueDocuments.ts`: hook now exposes the full issue-document list
## Verification
- `pnpm typecheck` — passes across the workspace
- `pnpm check:token-gates` — 3/3 CLEAN
- `cd ui && pnpm vitest run src/lib/issue-artifacts.test.ts
src/components/task-chat/task-chat-attachments.test.ts
src/pages/IssueDetail.test.tsx` — 74 tests pass
- Manual: open a task whose agent created a document not named `plan`
(for example `synthesis`); confirm it appears in the Plan tab below the
plan and in the Artifacts tab; confirm an image the agent attached
appears under Artifacts; confirm a user-uploaded image stays only in the
thread and opens full screen with a download button
Snapshot baselines are intentionally not updated for this visual change,
per the `doc/design/DECISION-SHEET.md` entry "Per-change snapshot
verification demoted to dormant (Jul 13 2026)".
## Risks
- Low risk: rendering-only change scoped to the task sidebar and thread
bubbles; composition logic is pure and unit-tested
- Dedupe relies on `metadata.attachmentId` linkage; a work product with
malformed metadata would render as a duplicate row (cosmetic only)
## Model Used
- Claude (Anthropic), model id `claude-fable-5`, extended thinking
enabled, agentic tool use via Claude Agent SDK (Claude Code harness)

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Operators talk to their agents on the issue detail page. An
experimental "Chat-Style Tasks" view (#10606) makes that page read as a
conversation instead of a ticket form.
> - The first release of that view shipped with a plain-text composer,
no visible narration while an agent works, and a desktop-only layout.
> - Users write formatted replies, paste screenshots, and follow long
agent runs from their phones. The experimental view should support all
of that before it can graduate.
> - This pull request is the next iteration of the same experiment: a
rich-text composer with attachments, live-turn narration on the status
line, cleaner settled-turn history, and a mobile layout.
> - The benefit is a chat view that feels alive while the agent works
and stays readable after it finishes, on desktop and mobile, still fully
behind the existing opt-in flag.
## Linked Issues or Issue Description
Refs #49 (chat with agents is a much-wanted feature).
Refs #10606 (the merged first release of the experimental chat-style
task view; this PR iterates on it).
Related PRs found in the dedup search:
- #8228 — open PR that polishes the classic issue chat composer. It
targets the flag-off legacy path; this PR only changes the flag-on
experimental view.
- #10466 — merged blockquote-recovery fix in the shared MarkdownEditor.
This PR now reuses that editor inside the chat composer.
**What existing behavior does this improve?**
The experimental "Chat-Style Tasks" view on the issue detail page
(Settings → Experimental, `enableTaskChatRedesign`, default off).
**Subsystem affected**
UI (issue detail page, chat-style task view).
**Current behavior**
With the experiment enabled, the composer is a plain textarea with no
formatting, no attachment preview, and no mention support. While an
agent runs, the status line shows only a static label, and the agent's
narration text is hidden. Finished runs render one settled row per turn,
so a run with many short turns produces a long list of near-duplicate
"Worked" rows, and turns without a comment append at the bottom out of
order. On mobile, the desktop bounded-height thread makes the page
scroll poorly.
**Proposed behavior**
The composer uses the shared MarkdownEditor: markdown formatting,
mentions, image paste with thumbnail previews, and non-image attachment
chips. Sending posts on Cmd/Ctrl+Enter. While an agent runs, the status
line rotates playful status words and surfaces the agent's own narration
as short interstitial updates: each update holds for a minimum dwell, is
replaced only when superseded, and slides through a one-line viewport
with tokenized motion. Back-to-back settled turns coalesce into one
"Worked" row with summed durations and re-derived tool counts, and
comment-less settled turns insert chronologically at their run's start
time. On mobile, the thread renders in the document flow with window
auto-follow and a sticky safe-area composer; the desktop layout is
unchanged.
**Reason and benefit**
The chat view is only convincing if it feels like a conversation with a
working agent. Rich text and screenshots are table stakes for chat
input. Live narration gives moment-to-moment feedback without opening
transcripts. Coalesced history keeps long-running tasks readable. Mobile
support lets operators follow runs away from their desks.
**Breaking changes**
None. Every change is gated behind the existing `enableTaskChatRedesign`
flag, which is off by default. The flag-off page is unchanged.
## What Changed
- `TaskChatComposer` swaps its textarea for the shared `MarkdownEditor`:
markdown formatting, mentions, image paste with object-URL thumbnail
previews (revoked on clear and unmount), and posting on Cmd/Ctrl+Enter.
- Non-image attachments render as chips on a new shared
`ui/attachment.tsx` primitive (adds the `@base-ui/react` dependency it
builds on).
- New `status-whimsy.ts`: deterministic rotation of playful status words
on the live status line.
- Live interstitial narration: the transcript adapter tags agent
self-talk, and the live status line shows it as ephemeral one-line
updates with a ~4s minimum dwell, hold-until-superseded replacement, and
a slide transition driven by new `--motion-line-scroll` tokens
(cataloged in `motion-tokens.ts`, which a test keeps 1:1 with
`index.css`). Hover affordance applies only to the status line, with no
leading icon.
- Settled-turn history: `coalesceSettledTurns` merges back-to-back
settled agent turns into one "Worked" row (summed per-run durations,
tool counts re-derived from the merged turn); `assembleThreadItems`
inserts comment-less settled turns chronologically at run start instead
of appending them at the bottom; settled turns render tool rows only
(the separate thinking block component is removed).
- The "Worked" summary attaches to the reply timestamp row, and thread
timestamps are always visible.
- Mobile layout: the thread renders with `scroll={false}` in the page
scroll, a new `useWindowAutoFollow` hook keeps the window pinned to new
content, the composer is sticky with safe-area padding, and the editor
uses 16px text so iOS does not zoom on focus. The desktop bounded chain
is untouched.
- New `TaskChatDescriptionBubble` renders the issue description as the
first chat bubble, and `McpIcon` gives MCP tools a distinct icon.
- `IssueDetail.test.tsx` stubs `TaskChatThread`: the composer's
`@mdxeditor` dependency cannot load under jsdom's CSSOM, and the suite
exercises the flag-off path.
## Verification
- `pnpm check:token-gates` — 3/3 CLEAN.
- `node scripts/check-task-chat-motion.mjs` — OK (30 files scanned,
seams present).
- `cd ui && npx tsc -b` — clean.
- `cd ui && pnpm vitest run` — 3,482 of 3,483 tests pass locally. The
one failure is the `IssueProperties.test.tsx` monitor-row
time-formatting test, which is timezone-sensitive: it fails identically
on unmodified `origin/master` in a non-UTC timezone and passes with
`TZ=UTC`. It is not related to this change.
- Manual: enable "Chat-Style Tasks" in Settings → Experimental and open
an issue with an assigned agent. Comment to start a run: the status line
rotates status words and shows the agent's narration as short held
updates. After the run, consecutive turns fold into one "Worked" row
under the reply timestamp. Paste an image into the composer to see a
thumbnail chip; attach a non-image file to see a file chip; send with
Cmd+Enter. Open the same issue in a narrow viewport to see the
document-flow layout with the sticky composer.
- Visual snapshot baselines are intentionally not updated: per
`doc/design/DECISION-SHEET.md`, "Per-change snapshot verification
demoted to dormant (Jul 13 2026)".
## Risks
- The composer now loads the shared MarkdownEditor inside the chat view.
The editor is already used across the app (issue descriptions,
comments), so its behavior is well exercised; composer-specific handling
(paste, attachments, submit keys) is covered by new tests.
- The transcript adapter changes how live narration and settled turns
are derived from run logs. Malformed or legacy logs degrade to generic
rows rather than crashing, and the adapter suites cover the merge and
ordering rules.
- Object URLs for paste previews are revoked on send-clear and unmount
to avoid leaks; jsdom environments without `URL.createObjectURL` are
guarded.
- All changes are behind the default-off `enableTaskChatRedesign` flag.
Overall risk with the flag off is low.
## Model Used
- Claude (Anthropic), model id `claude-fable-5` (Claude Fable 5),
extended thinking enabled, agentic tool use (file editing, shell, test
execution) via Claude Code / Claude Agent SDK.
