crq dismiss records its decision only in the state ref. A PR with outside-diff or review-body findings then shows the reviewer's comments with no answer, so it looks as if crq missed them. crq decline does not have this problem because it replies on the thread.

After a dismissal is recorded, crq now posts one issue comment through the same PostIssueComment path as hold notices:

<!-- crq:dismiss -->
Dismissed 2 findings at `aaaaaaaa1`:

- coderabbitai: Add the missing install warning. (`README.md:7`, [source](…))
- coderabbitai: The parser accepts stale state. (`src/app.ts:12`, [source](…))

**Reason:** …
  • One comment per call. All IDs dismissed together are listed in one comment.
  • Idempotent. Only IDs this call newly recorded are listed. A replay, or a concurrent call that loses the CAS, posts nothing.
  • The record is the source of truth. If the post fails, the dismissal stands and the JSON result carries warning. On success it carries comment_url. Dry runs post nothing.
  • Never read back as feedback. The comment is authored by crq's user, not a feedback bot, and it never equals a trigger command. Titles and reasons go through neutralizeReviewCommands, so a quoted @coderabbitai or review command cannot ping or trigger a reviewer. crq tidy only deletes recorded trigger comments, so it leaves the notice alone.

There is no opt-out, which matches hold notices and decline replies.

Docs updated: README, llms.txt, the bundled skill, the autofix prompt and crq help dismiss.

See kristofferR/IPTVChecker#248

Summary by CodeRabbit

  • New Features
    • Dismissing findings now posts one pull request comment listing the findings and reason. Dismissing multiple findings together includes them in the same comment; replaying a dismissal does not post another.
    • Successful comments include a link in the dismissal result. If posting fails, the result includes a warning and the dismissal remains recorded.
    • Dismissal confirmations now explain that the reason and findings will be posted in a pull request comment, and returned warnings are shown in the interface.

crq dismiss recorded its decision only in the state ref, so a PR showed a
reviewer's threadless findings with no answer. Each call that records a
dismissal now posts one issue comment naming the findings and the reason.
A replay posts nothing, and a failed post is reported as a warning without
undoing the dismissal.

Consider truncating the reason to bound the comment size.

dismissComment writes reason in full into the PR comment. A very long reason, or many findings, can exceed the GitHub comment size limit of 65536 characters. In that case, PostIssueComment fails and the user gets only a warning. The dismissal remains recorded, so the failure is safe. It is an edge case.

The design still meets the requirement: a failed post does not undo the dismissal.

📝 Walkthrough

Walkthrough

crq dismiss now posts one PR comment for newly dismissed findings. The result includes the comment URL or a warning if posting fails. The dismiss action returns warnings to clients. Help text, agent guidance, and tests describe the behavior.

Return warnings to clients
internal/serve/actions.go, internal/serve/server_test.go, cmd/crq/main.go, web/src/PRDetail.tsx
The dismiss action returns posting warnings through the server response. The web interface displays warnings from finding and round actions. Dismiss confirmations state that the reason and finding are posted in a PR comment.
Document dismissal behavior
cmd/crq/main.go, README.md, internal/crq/dispatch/fix-prompt.txt, llms.txt, skills/codereview-queue/SKILL.md
Help text and agent guidance state that multiple IDs in one call share a comment, replay posts no comment, and a posting failure does not undo the dismissal.

Merge Risk: ⚪ Minimal · up to 417fa

Dismissal notices and posting warnings are consistent across CLI and dashboard behavior. No actionable merge-blocking issue remains in the supplied evidence; merge after normal checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 417fa

The new notice stays attached to the selected PR and follows existing dismissal validation. Repeated calls do not repost, and posting failures leave the decision intact while returning a warning. No security bypass was demonstrated, but deployed permissions and external reviewer behavior remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • observed — Each notice write is scoped to one validated repository and PR. Finding text and source links affect the comment body, not its destination; the comment becomes visible to readers of that PR.

Trust Boundaries and Controls

  • observed — The HTTP dismissal action retains read-only enforcement, the dashboard-header requirement, addressed-host validation, bounded request decoding, and PR, finding-ID, and reason checks. These existing controls precede the newly added posting behavior; they are not per-user authentication.
  • observed — The complete rendered notice passes through neutralizeReviewCommands, covering configured commands, known aliases, and mentions. Paths receive code-span formatting and titles are shortened. Source URLs remain direct Markdown links; these controls do not establish a complete link or Markdown policy.
  • observed — Issue-comment feedback extraction checks the comment author against the configured evidence-bot set. An ordinary posting user outside that set does not gain reviewer identity merely by quoting a finding. Returned warnings are displayed as React text rather than HTML.

Resilience and Maintainability Implications

  • observed — CAS mutation resets its output on every attempt, so only IDs newly recorded by the successful attempt feed the notice. Replays produce no notice, and dry runs use throwaway state and skip posting. Interruption after commit can lose notification delivery without changing the recorded decision.
