## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Agents ask the board for decisions with `request_confirmation`
interaction cards
> - The compact task-chat card puts the prompt and the target pill in
one `justify-between` flex row
> - An agent can send a `custom` target with only a machine `key` (for
example `github:org/repo:pull:16`) and no `label`
> - The card shows that raw key as a mono pill that does not shrink, so
the card splits about 50/50 and the prompt is squeezed into the left
half
> - This pull request stacks the prompt above the pill and hides custom
targets that have no human label
> - The benefit is a readable, full-width confirmation prompt without
meaningless identifier pills
## Linked Issues or Issue Description
**What happened?**
A pending confirmation card split its body into two columns. The prompt
used the left half. A pill with the raw text
`github:paperclipai/paperclip-desktop:pull:16` used the right half. The
line breaks in the prompt were also lost.
**Steps to reproduce**
1. Create a `request_confirmation` interaction with a multi-line
`prompt` and `target: { "type": "custom", "key":
"github:org/repo:pull:16" }` (no `label`).
2. Open the task chat for the issue.
3. See that the prompt and the key pill share one row, split about
50/50.
**Expected behavior**
The prompt uses the full card width and keeps its line breaks. A custom
target key is an identifier for idempotency and stale detection, so it
does not show as display text. A target pill shows only when the target
has a human label.
## What Changed
- `TaskChatCompactInteractionCard`: stack the prompt full width with the
target pill below it. This applies to the confirmation and the
checkbox-confirmation cards.
- `TaskChatCompactInteractionCard`: keep line breaks in the prompt
(`whitespace-pre-line`, `break-words`).
- `TaskChatCompactInteractionCard` and `IssueThreadInteractionCard`:
show no target chip for a `custom` target without a `label`. Labeled
custom targets (for example connection authorization) and
`issue_document` targets do not change. The stale-target chevron shows
only when both chips show.
- Add regression tests for the stacked layout, the hidden unlabeled key,
and the labeled link pill. The tests cover the compact confirmation and
checkbox-confirmation cards, and the thread card pending chip and
stale-target expiry (with labeled, unlabeled, and mixed custom targets,
and the chevron rule).
- `CONTRIBUTING.md`: add a "Keep Screenshots Out of the Repo" section.
Contributors attach review screenshots to the PR on GitHub. They do not
commit them to the repository.
## Verification
- `cd ui && npx vitest run
src/components/task-chat/TaskChatInteractionCard.test.tsx
src/components/IssueThreadInteractionCard.test.tsx`: 2 files, 100 tests
pass. If you revert the `isDisplayableRequestConfirmationTarget` guard,
3 of the new thread-card tests fail.
- `node scripts/check-token-gates.mjs`: all gates clean.
- `pnpm --filter @paperclipai/ui typecheck`: no errors in changed files.
The only errors come from `@paperclipai/plugin-sdk/ui`, which had no
built `dist` in the local workspace. These errors are not related to
this change.
- Manual: create a confirmation as in the steps above. The prompt is
full width and no key pill shows. Add `label: "PR #16"` and an `href`. A
`PR #16` link pill shows below the prompt.
### Screenshots
These are Storybook renders of the compact task-chat card at 720 px. The
three cards are: a confirmation with an unlabeled custom target (the
reported case), a confirmation with a labeled custom target, and a
checkbox confirmation with an unlabeled custom target.
The images load from an earlier commit of this PR. A later commit
deletes them, so they are not part of the merged change.

## Risks
- Low risk. This is a UI-only change. No schema or API change.
- Agents that send a custom target without a label lose the visible
pill. The key was never readable display text. To show a pill, agents
set `label`.

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 config, stories, and fixtures live under ui/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.
