Unlinking a pull request from a thread is reachable from the thread's pull-requests panel, or from a right-click on the original URL in the transcript. Neither is where a reader is looking when they notice the wrong number. That is the badge on the sidebar row, and a right-click on it opened the platform's own edit menu over a control with nothing to cut or paste.

Those numbers now carry the same menu the transcript link does: Copy link, Open on GitHub (or whichever host it came from), and Unlink from thread last, behind a divider.

The later commits take the same idea to the chat header, where the number was not shown at all.

How: right-click to unlink

  • ThreadPullRequestBadgeControl takes an optional onContextMenuPullRequest, which covers every row that wears a number in one place. The stack shape does not get one, because a stack has no single number to act on.
  • useThreadPullRequestLinkContextMenu builds the handler over usePullRequestLinking, so servers on thread.pull-request.unlink and older ones on legacy linkedPullRequest metadata both route correctly. A server that supports neither offers no unlink item at all.
  • The legacy sidebar's own anchors get the same handler. Without it the row's thread menu answered, since the number sits inside the row.
  • The unlink item names its number: Unlink Add Expo mobile client and wire up dev:mobile workflow #123 from thread, read off the URL the menu was opened on. A thread holding several links wears one aggregate badge that reads +3 rather than a number, and the destructive item should not be the one thing on screen that does not say what it acts on.
  • The handler resolves its linking state on the click instead of subscribing. It is mounted once per row of the thread list, and nothing it reads is needed until a right-click lands, so a project or server-config change no longer wakes every row.
  • Unlink is offered only for a pull request the thread is actually linked to. The same badge also shows one read off the thread's branch, and that is a fact about git rather than a choice to undo, so it keeps copy and open only.

Whether the thread is linked is read when the menu opens and again when the item is chosen. A menu sits open for as long as it takes to read, and the agent can link or unlink from underneath it in that time, so clearing whatever happens to be there by then would unlink something nobody chose. Same guard ChatMarkdown already applies to the transcript link.

How: the header's pull request button

The header's git actions button answered two questions at once. It read "Commit & push" while work was in flight and "View PR" once it landed, so the control under the cursor changed meaning as the branch did, and the number the thread carried was nowhere in the header.

  • ThreadPullRequestHeaderPill sits beside the git actions. Linked, it shows #123 with the same status colour the sidebar badge uses and opens the Linked pull requests panel, because the number is also the handle for changing which pull requests the thread carries. Right-click gets the menu above, unlink included.
  • With no pull request yet it reads Create PR and runs the same create flow. That flow stays in GitActionsControl with its progress stages, default-ref confirmation and result toast; the pill reaches it through a window event, so neither corner of the header has to own the other's state.
  • resolveThreadPullRequestHeaderPill decides between linked, create and hidden. The create gate mirrors the one the old menu item used, so the button appears exactly where "Create PR" used to be offered and nowhere it was not. Hidden is the answer when creating one would only produce an error toast.
  • The git actions button now only moves the ref along: commit, push, pull, publish. Where it has nothing left to do but a pull request could still be opened or read, its hint points at the new button rather than claiming no action is needed.
  • The pill reads the vcsEnvironment.status atom the git actions control already reads, so the header still asks for one status.

How: the composer's badge goes

The branch toolbar carried a ghost-styled copy of the sidebar badge. It showed a number and nothing else, a few hundred pixels from the header button that now shows the same number with somewhere to go. Removing it leaves resolveBranchToolbarPrBranch with no caller and ThreadPullRequestBadgeControl with one variant, so both collapse. The sidebar badge is unchanged, and so is the right panel's stack surface, still reachable from the header button, the sidebar badge and the command palette.

Surfaces

  • Web / desktop: both sidebars and the chat header. Desktop gets the native menu through the bridge, web gets the DOM fallback.
  • Mobile: unchanged. There is no right-click, no chat header of this shape, and the linked pull requests panel is how mobile reaches this.
  • Server / contracts: unchanged. thread.pull-request.unlink and the legacy path both already existed.
  • Capabilities: without threadPullRequests there is no linked-pull-requests panel to open, so the header button falls back to the existing onOpenPullRequest and opens the review beside the thread.
  • Reverse state: linking already existed on the transcript link and in the link dialog; this is the way back out from the places the link is visible.

Verification

  • vp test run apps/web/src/components/BranchToolbar.logic.test.ts apps/web/src/components/ThreadStatusIndicators.test.ts apps/web/src/components/composerFooterLayout.test.ts apps/web/src/components/Sidebar.logic.test.ts apps/web/src/components/pullRequest/ — 26 files, 675 tests pass. Four cover the new menu: the default two items, the third item and its divider, the URL handed to the callback, and the host labels.
  • vp test run apps/web/src/components/GitActionsControl.logic.test.ts apps/web/src/components/pullRequest/threadPullRequestHeaderPill.logic.test.ts — 13 new tests cover each reason the header button shows a number, offers to create one, or stays hidden.
  • tsc --noEmit in apps/web clean.
  • vp lint on the touched files adds no warnings; the ones it reports are pre-existing and on untouched lines.
  • Rebased onto main after fix(web): keep the composer ready during background worktree setup #11883 and fix(mobile): match command palette colors to sheets #11861; neither touches a file this branch changes. Re-ran the suites above on the new base: 27 files, 740 tests pass.

Before / after

Same thread, same branch, same open pull request, same clean tree. Only the app code differs.

Chat header — the pull request number had no place in it before; now it has its own pill beside the git actions, which no longer changes meaning as the branch does.

before after
header before header after

Branch toolbar — the ghost badge showed the same number a few hundred pixels away, with nowhere to go.

before after
composer before composer after

Supersedes #11893, which was written against the pre-thread.pullRequests code and had drifted too far to rebase. Closes #11087.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This change adds a new cross-surface context-menu workflow that can mutate persisted thread pull-request linkage, including compatibility handling for multiple server modes. The implementation is localized and tested, but the new user-facing capability and state-changing action merit human review.

The disabled quick action told the reader the pull request was on the
header's own button whenever the ref had an open one. The header's pill
shows the thread's pull request, and a ref can carry one the thread never
linked, so the hint sometimes pointed at nothing.

Report it as a fact about the ref instead: "This ref already has an open
pull request." The create hint still names the button, because the pill's
create gate and that branch of resolveQuickAction agree, and both
controls render under the same activeProjectName and gitCwd.

Unlinking a pull request from a thread was reachable from the thread's
pull-requests panel, or from a right-click on the original URL in the
transcript. Neither is where a reader is looking when they notice the wrong
number: that is the badge on the sidebar row and the pill in the branch
toolbar, and a right-click there opened the platform's own edit menu.

Those numbers now carry the same menu the transcript link does, with
**Unlink from thread** last and behind a divider. It is offered only for a
pull request the thread is actually linked to; the number a thread picked up
from its branch keeps copy and open, because nothing linked it to undo.

Whether the thread is linked is read when the menu opens and again when the
item is chosen. A menu sits open for as long as it takes to read, and the
agent can link or unlink from underneath it in that time, so clearing
whatever happens to be there by then would unlink something nobody chose.

The work goes through `usePullRequestLinking`, so servers on
`thread.pull-request.unlink` and older ones on the legacy
`linkedPullRequest` metadata both route correctly, and a server that
supports neither offers nothing.

The git actions button answered two questions at once. It read "Commit &
push" while work was in flight and "View PR" once it landed, so the
control under the cursor changed meaning as the branch did, and the
number of the pull request a thread carried was nowhere in the header.

Split them. The git actions button now only moves the ref along: commit,
push, pull, publish. Beside it sits a pull request button that shows the
thread's number, opens the Linked pull requests panel, and right-clicks
to unlink. With no pull request yet it reads "Create PR" and runs the
same create flow, which stays in GitActionsControl with its progress
stages, default-ref confirmation and result toast, reached through a
window event so neither corner of the header has to own the other's
state.

Where the quick action has nothing left to do but a pull request could
still be opened or read, its hint points at the new button rather than
claiming no action is needed.

The branch toolbar carried a ghost-styled copy of the sidebar's linked-PR
badge. It showed a number and nothing else, and the header now shows the
same number with somewhere to go: the Linked pull requests panel, where
the thread's pull requests are actually managed, plus Create PR when
there is none. Two reads of the same fact, a few hundred pixels apart,
and the composer one was the thinner of them.

Removing it leaves resolveBranchToolbarPrBranch with no caller and the
badge control with one variant, so both collapse. The sidebar badge and
the stack doorway it opens are unchanged.

A thread that holds several links wears one aggregate badge that reads
"+3" rather than a number, and right-clicking it offered a bare "Unlink
from thread" over whichever link is current. The menu now reads
"Unlink pingdotgg#123 from thread", derived from the url it was opened on, so the
destructive item names its target everywhere the number is written.

The same hook also stopped subscribing to the projects and server-config
atoms. It is mounted once per row of the thread list, and nothing it
reads there is needed until a right-click lands, so the linking state is
now resolved from the registry inside the handler. A project or config
change no longer wakes every row, and the projects array is no longer
filtered once per row on mount.
