feat(web): unlink a pull request from its thread - #11893
ElliotDrel wants to merge 3 commits into
Conversation
A thread linked to a pull request settles itself when that PR merges. The only way to undo the link was to right-click the original PR URL in the chat transcript, which is unreachable once that message scrolls away. Adds "Unlink from thread" to the PR number's context menu in both sidebars, and a PR chip in the chat header beside the git actions that shows the linked number and carries the same open/unlink behavior. The item only appears for the number the thread is actually linked to, so a PR read off the thread's branch still offers just copy and open. No server or contract change: thread.meta.update already accepts a null linkedPullRequest. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

The sidebar row's number and the thread header's chip now carry the same unlink action as the link in the conversation, so the paragraph that only described the conversation link was no longer the whole story. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Suggested reviewers: Merge Risk: 🟡 Moderate · up to A delayed unlink action from another device can remove a pull request that was linked more recently, so the operation needs server-side conditional update semantics before merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

However, it does not include the required Checklist section, and it explicitly notes that the required before/after images and interaction video for the UI changes are still missing.

ℹ️ About Codex in GitHub
Your team has set up Codex to review pull requests in this repo. Reviews are triggered when you
- Open a pull request for review
- Mark a draft as ready

If Codex has suggestions, it will comment; otherwise it will react with 👍.
Codex can also answer questions or update the PR. Try commenting "@codex address that feedback".
A context menu stays open for as long as it takes to read, and in that time the agent can write a newer pull request link or another device can change the thread. Clearing whatever the thread holds by then would unlink something nobody chose. The unlink callback now takes the URL the reader acted on, re-reads the thread shell, and drops the request unless that is still the link the thread holds — the same guard the transcript path already applies in ChatMarkdown.

A thread linked to a pull request settles itself when that PR merges. Until now the only way to undo that link was to right-click the original PR URL in the chat transcript, which is unreachable once the message scrolls away and impossible if the link was never written there.
What changed
<host>, and, only when that number is the one the thread is linked to, Unlink from thread last and behind a divider.docs/user/thread-sidebar.mdalready described unlinking from the conversation link. It now names the two new places as well.A pull request merely read off the thread's branch still offers only copy and open. That one is a fact about git, not a choice to undo.
Notes
No server or contract change.
thread.meta.updatealready accepts a nulllinkedPullRequestand the decider already passes it through, so this is only the missing way to ask for it.The action is gated on the
threadPullRequestLinkingcapability, so a server that never records a link does not offer to clear one.Unlinking is given the URL the menu was opened on and re-reads the thread shell before it fires, so a menu left open while the link changes underneath declines instead of clearing the replacement. Same guard the transcript path applies.
Web only. Mobile reads
linkedPullRequestbut has never written it, so unlinking there is a separate change.Verification
vp test run apps/web/src/components/pullRequest/pullRequestLinkContextMenu.test.ts— 5 passing, 3 of them new. Web typecheck clean, lint clean over the changed files.Before/after images still to come; happy to attach them on request.
