DottaandClaude Opus 5.5 07a548073a fix(ui): keep inline document links in the text line; plain-text request previews (#19639)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Agents talk to people in task chat. Their messages render as
markdown.
> - In an onboarding walk, two chat papercuts made agent text hard to
read.
> - First: a document link inside a sentence ("Your [plan is saved],
approved, ...") rendered as a padded card. The card is taller than the
text line, so it overlaps the lines around it.
> - Second: the one-line row above a pending review card showed the
agent's raw markdown summary (backticks, "- ", "**").
> - This pull request renders document links in running text as an
inline chip, and flattens the collapsed preview to plain text.
> - The benefit is that agent messages and pending-request rows read
cleanly.

## Linked Issues or Issue Description

**What happened?**
1. In task chat, an agent wrote: "Yes—we completed the onboarding
interview here in chat. Your [plan is saved](#document-plan), approved,
and handed off to execution task PIX-3." The "plan is saved" link
rendered as a 42px-tall bordered card in a 20px text line. It overlapped
the text above and below and left the text baseline.
2. The collapsed row above a "Review the creative brief (v1)" card read:
"The `creative-brief` document is saved on this task. It covers: -
**Brand voice and audience:** ..." with literal markdown syntax.

**Steps to reproduce**
1. Open a coordinator task chat where an agent message has a
`#document-...` link inside a sentence. Or open the Storybook story
`coordinator-conversation--inline-document-link`.
2. Open a task with a pending request whose summary contains markdown.
Or open
`composer-interaction-above-composer--pending-request-markdown-summary`.

**Expected behavior**
1. The document link sits in the text line like other inline links.
2. The collapsed preview shows the words as plain text.

## What Changed

- `SidebarDocumentLink` gets a `variant` prop. `card` (default) is
unchanged and is still used by the standalone plan preview card.
`inline` is a text-flow chip: `display: inline`, horizontal padding
only, a small muted background, and a 14px icon aligned to the text
bottom. Token classes only.
- `MarkdownBody` uses the `inline` variant for both document-link paths
(coordinator issue document links and `#document-...` hash links). The
label no longer uses `truncate` (nowrap), so long labels wrap with the
sentence.
- New `ui/src/lib/markdown-plain-text.ts` (`markdownToPlainText`): drops
code ticks, emphasis/strikethrough markers, list/heading/quote/task-box
prefixes, fences, rules, link/image targets and inline HTML tags, keeps
snake_case intact, and collapses whitespace. Unit tests included.
- `TaskChatInteractionCard` flattens the collapsed pending-request
summary and the unanswered-question prompt with `markdownToPlainText`.
- Stories: `Coordinator conversation / Inline document link` (+ dark)
with a play check that the link is no taller than the line and starts
inside the paragraph; `Interaction above composer / Pending request
markdown summary` with a play check that the row has no markdown syntax.

## Verification

Red on master (`e482f0f632`), then green with the fix:

```
# Red (master + new tests)
 × renders a document link inside a sentence as inline text, not a padded card
   AssertionError: expected 'inline-flex max-w-full items-center gap-2 rounded-lg border border-border bg-muted/25 px-3 py-2.5 ...' not to match /(^|\s)(inline-flex|flex|block|py-\S+|p-\S+)(\s|$)/
 × shows the collapsed pending-request preview as plain text, not raw markdown
   AssertionError: expected 'Review the creative brief (v1)The `cr…' to contain 'The creative-brief document is saved …'
 Tests  2 failed

# Green (fix)
 Tests  7 passed  (the 2 above + 5 markdownToPlainText unit tests)
```

Browser geometry check (Playwright against Storybook, story
`coordinator-conversation--inline-document-link`, light and dark). It
measures the link box against the paragraph line-height and the text
node before the link:

```
# Before
light: FAIL lineHeight=20 chipHeight=42.0 chipTop=61.7 chipBottom=103.7 textTop=76.7 textBottom=93.7
dark:  FAIL lineHeight=20 chipHeight=42.0 chipTop=61.7 chipBottom=103.7 textTop=76.7 textBottom=93.7
# After
light: PASS lineHeight=20 chipHeight=17.0 chipTop=62.7 chipBottom=79.7 textTop=62.7 textBottom=79.7
dark:  PASS lineHeight=20 chipHeight=17.0 chipTop=62.7 chipBottom=79.7 textTop=62.7 textBottom=79.7
```

The story's own play function also failed on master in the browser:
`AssertionError: expected 42 to be less than or equal to 20`.

Inline document link, before / after (dark, then light):

Neighbouring suites: `npx vitest run src/components/MarkdownBody
src/components/task-chat src/lib/markdown-plain-text.test.ts
src/components/MarkdownDocumentCardStyles.test.ts
src/components/MarkdownExternalLink.test.tsx` → 67 files, 1001 tests
passed.

Also run: `pnpm check:token-gates` (clean), UI `tsc -b` (no errors in
changed files; the only errors were an unbuilt local
`@paperclipai/plugin-sdk`), `node scripts/storybook-catalog.mjs`. `pnpm
verify` exited 2 (story file is a broad input), so broad coverage comes
from required CI.

## Risks

- Low risk. UI-only styling and text change.
- Document links in markdown now look like inline links with a small
icon instead of a card. A link that sits alone in its own paragraph also
renders inline. The standalone plan preview card keeps the card style.
- `markdownToPlainText` is a regex flattener for one-line previews, not
a full markdown parser. An unusual construct can keep a stray marker. It
does not change stored data.

## Model Used

- Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, via Claude Code with
tool use (shell, file edits, Playwright browser checks).

@paperclipai/ui

Published static assets for the Paperclip board UI.

What gets published

The npm package contains the production build under dist/. It does not ship the UI source tree or workspace-only dependencies.

Storybook

Storybook config, stories, and fixtures live under ui/storybook/.

pnpm --filter @paperclipai/ui storybook
pnpm --filter @paperclipai/ui build-storybook

Typical use

Install the package, then serve or copy the built files from node_modules/@paperclipai/ui/dist.

Editor dependency identity

Keep the root and workspace overrides for @codemirror/state, @codemirror/view, and @lezer/common aligned. CodeMirror requires shared extension identity, while Lezer parsers and syntax highlighters require shared NodeProp IDs. Multiple Lezer copies can crash code-block highlighting with tags is not iterable. src/lib/codemirror-single-instance.test.ts checks the installed dependency graph and highlights sample code through the editor's real language dependencies. GitHub Actions owns regeneration of pnpm-lock.yaml.
