Problem

Sending more than one pull request finding or diff selection to the composer lost the earlier ones. Each new "Add to agent" or "Fix finding" replaced the draft's text, or, if you'd typed a line break, dropped the previous chip and kept only the new one. Reproduction is in #24960.

Change

  • Handoffs now append. Lines the draft doesn't already contain go after what's there, and chips merge by id, with the newer copy winning. Sending the same handoff twice changes nothing, and the pull request preamble isn't repeated for a second finding.
  • The panel and usePullRequestActions share one writeHandoffToComposer instead of each keeping its own copy.
  • Selection and finding chips from a pull request show its number (#24945 ElectronMenu.ts L78), so comments on the same file in two pull requests can be told apart. Chips from a thread's own diff are unchanged.
  • The pull request context and guide-stop chips are keyed by URL instead of number, so two repositories with the same pull request number no longer overwrite each other's context.

Known limit: an identical line is only added once. Asking "why?" on two selections shows the question once, followed by both chips.

Scope and approval

Fixes #24960, which has no maintainer reply yet. Handoffs have replaced the draft since #4849; if that is still intended, I'm happy to adjust or close this.

Verification

  • pullRequestDetail.logic.test.ts: new cases for keeping earlier findings and selections, typed text, newer chip copies, repeated handoffs, the shared preamble, and two repositories sharing a pull request number. composerContextRecords.test.ts: the chip label names its pull request.
  • 293 tests pass across the pull request panel, composer context and draft store; lint, format and typecheck are clean on the changed files.
  • In the web app, I added a selection from fix(web): snooze times read naturally in context menus #24945 and then one from fix(claude): command approvals show the command, not Claude's description of it #20145 to the same draft. Before, only the second remained. After, both questions and their chips stay.
  • I couldn't run the pull request panel browser tests locally: Playwright has no headless Chromium for Ubuntu 26.04.

Each PR panel handoff replaced the previous one: chips with a
`pull-request-` id were stripped and the last handoff's text was cut
off the prompt. Handoffs now append their text and any chips not
already in the draft.

Fixes pingdotgg#24960

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A handoff now appends only lines the draft lacks, so repeating one or
adding a second finding does not copy the pull request preamble again.
A chip already in the draft takes the newer copy. Both composer writes
share one helper.

Approvability

Verdict: Approved at 757a6d4

Macroscope's review found this PR approvable — This is a focused web bug fix that preserves earlier pull-request findings and selections in the composer while consolidating the existing handoff paths. The production impact is limited to pull-request composer composition and chip labeling/identity, with targeted tests covering the changed behavior.

Walkthrough

Pull request handoffs now append distinct prompt text and merge review-comment contexts by ID. Pull request context IDs use URLs, and review-comment labels include the pull request number when available.

Changes: Pull request handoffs

Layer / File(s) Summary
Append handoffs and identify pull requests
apps/web/src/components/pullRequest/pullRequestDetail.logic.ts, apps/web/src/components/pullRequest/pullRequestDetail.logic.test.ts
appendHandoff appends nonduplicate prompt text and merges review-comment contexts by ID. Pull request context and guide-stop IDs use URLs. Tests cover prompt and chip retention, duplicate handling, and same-number pull requests with different URLs.
Write handoffs to the composer
apps/web/src/components/pullRequest/usePullRequestActions.ts, apps/web/src/components/pullRequest/PullRequestDetailPanel.tsx
writeHandoffToComposer combines existing draft content with a handoff. The pull request panel uses it for thread, ask, and handoff actions.
Label pull request review contexts
apps/web/src/lib/composerContextRecords.ts, apps/web/src/lib/composerContextRecords.test.ts
Review-comment labels include the pull request number when the section ID identifies a pull request. Tests cover pull-request and turn-diff labels.

Full details: Description check

Explanation

The description fills all template sections with the problem, implementation details, scope reference, focused verification, manual results, skipped browser-test limitation, screenshots, and agent metadata. It notes that issue #24960 has no maintainer reply, but the description is otherwise complete and relevant.

Full details: Linked Issues check

Explanation

Issue #24960 requires that multiple pull-request comments, selections, and findings preserve earlier prompt text and chips, and show the pull-request chip once. appendHandoff merges prompt lines and review-comment contexts by ID, with the incoming copy replacing an existing ID. writeHandoffToComposer reads and writes the complete draft, and the panel uses this shared path. Pull-request context and guide-stop IDs use the pull-request URL, which prevents collisions between repositories. The reported tests cover earlier handoffs, typed text, repeated handoffs, newer chip copies, shared preambles, and repositories with the same pull-request number.

Full details: Out of Scope Changes check

Explanation

The reviewed changes support issue #24960. The shared handoff writer and appendHandoff implement the required append and merge behavior. Pull-request chip labels include the pull-request number to distinguish references in one composer. URL-based context IDs prevent cross-repository collisions that would break the same handoff flow. Related tests and removal of the old replacement logic are supporting changes. No unrelated change is evident in the reviewed whole-pull-request summary or inspected files.

- Around line 837-841: Update the incoming-line filtering in appendHandoff to
deduplicate only generic preamble lines; preserve quoted entries and section
headers even when they already appear in the draft. Skip appending only when
every non-blank incoming line is already present, so an identical handoff
remains a no-op.
- Around line 1030-1037: Update appendHandoff to replace legacy numeric-key
pull-request contexts with incoming contexts matched by pullRequest.url, while
retaining the existing same-ID replacement behavior. Exclude incoming contexts
already used as replacements from the appended entries so a repeat handoff
produces one chip; preserve URL-based matching to distinguish repositories that
share a pull-request number.

Two "Fix findings" handoffs for different pull requests could share a
quoted check or remark, and the line dedupe dropped it from the second.
Quotes and their headers are now always kept; a handoff whose every line
is already present is still a no-op.

Supersede the ask context in a Fix handoff.

buildAskAboutPullRequestHandoff adds a pull-request context chip that says “Do not change any code.” buildFixFindingsHandoff adds only finding chips, so appendHandoff retains that earlier context. An Ask handoff followed by a Fix handoff can therefore leave the agent with conflicting instructions.

Add a neutral context chip to the Fix handoff. Its shared ID makes appendHandoff replace the ask context while preserving the pull-request reference.

thanks @TonybynMp4. i kept your commits, shared composer writer, chip merging, url identities, and pr labels, and merged main into this branch. the takeover is at 8a2e43c988d86be6eb27ec4ca9aee4e92222d003.

replaced line deduplication with whole-block comparison. distinct multiline requests keep their shared and reordered lines; repeating a complete block leaves it unchanged, including trailing-space cases. distinct findings can repeat their preamble. fixed the bot finding too: single and all-findings handoffs replace stale ask-only instructions with neutral pr context. the thread-details checks action uses the same path.

verification:

  • reproduced main dropping the first selection chip in system chrome through the real git.cafe pr panel.
  • reproduced failing regressions for multiline text, trailing-space repeats, and ask-to-fix instructions before each correction, in the existing test file.
  • blacksmith vp run check:changed passed format, lint, both knip checks, web/scripts typechecks, and 93 tests, including the existing thread-details browser tests. the earlier focused draft-store pass covered 160 tests.
  • real app: two selections retain both requests and chips; repeated additions stay unchanged; ask followed by single/all findings leaves one pr context without the old "do not change any code" instruction and retains the selections.
  • uploaded recording playback and seeking verified. desktop, native mobile, tunnel connections, and sending a provider turn remain unverified.

@TonybynMp4: retained your documented legacy-draft limit: an old number-keyed pr context can leave an extra removable chip. no migration was added for that nonblocking case.

main: the second selection removes the first selection chip

takeover: both multiline requests and both selection chips remain

adding two selections preserves their requests and chips

Verified in a real dev environment

verified unchanged head 8a2e43c988d86be6eb27ec4ca9aee4e92222d003 on this linux vm. installed dependencies and ran main (c3858bf1f7) and the exact pr head sequentially, with isolated empty state. used repository playwright with /usr/bin/google-chrome, created the project and conversation through the app, opened this pr's real git.cafe diff, and used codex gpt-6.1-sol through the running web client and server. no mocks, fixtures, or demo data.

  • main: added line 216, then line 217 of ThreadDetailsPrRow.tsx. the first selection chip disappeared. the submitted message contained only line 217's diff, and codex reported the first selection's code missing.
  • pr: both requests and both numbered chips remain. the submitted message contains both diffs, and codex reports both exact lines. confirmed the actual model and completed runs from the persisted server events.
  • nearby behavior: repeating a selection or single/all-findings handoff leaves the draft unchanged; typed text survives two distinct finding handoffs; ask followed by single/all findings replaces the ask-only instructions with one neutral pr context. clearing the composer and adding one selection leaves only that selection. both selections survived a browser reload.
  • blacksmith: vp test run apps/web/src/components/pullRequest/pullRequestDetail.logic.test.ts apps/web/src/lib/composerContextRecords.test.ts apps/web/src/composerDraftStore.test.ts passed all 161 tests. existing ci reports 27 successful checks, zero pending or failing. no source changes or push were needed.

runtime transcript from the real submitted contexts and provider responses:

main: provider=codex model=gpt-6.1-sol status=completed
submitted: +217 isDraft: detail.isDraft,
assistant: selection alpha: no selected lines or state code arrived.

pr: provider=codex model=gpt-6.1-sol status=completed
submitted: +216 state: detail.state,
submitted: +217 isDraft: detail.isDraft,
assistant: this message's attached context contains two selections:
alpha, line +216: state: detail.state,
beta, line +217: isDraft: detail.isDraft,

main: adding line 217 drops line 216's selection chip

pr head: both matching selection requests and numbered chips remain

real app: two additions preserve typed text and both selection chips

inspected both full-size screenshots and the exported recording. uploaded images render, and uploaded video playback and seeking work in chrome.

Not verified

native desktop shells, ios/android, macos/windows, remote/tunnel connections, and other providers were not exercised on this linux vm. same-number cross-repository contexts and guide-stop handoffs were covered only by existing focused tests, not a real multi-repository flow. the server's automatic project selection used its default server workspace, which is inside this real git checkout; no code-editing provider turn was requested. no mergeability claim against today's moving main.
