Why

The CodeRabbit CLI review step (ADR-0036) only reviews factory cards. On a PR opened by hand, nothing reviews a head commit the rate-limited PR bot skips, so /merge stopped with "CodeRabbit is rate-limited and has not reviewed this commit" (#637). Waiting for the bot's hourly limit to reset was the only way through.

What

coderabbit-cli.mjs review --pr N --repo-root R [--state-file F] [--timeout-min M] runs the CodeRabbit CLI on a hand-made PR's head and waits for it.

  • Same checks, same posting. It skips a head the bot reviewed or is reviewing, a head a CLI review already covered, and a PR that is no longer open. It reviews incrementally from the nearest bot-reviewed commit, or in full against the merge-base. Findings are posted through the lane's postFindings, so they become review threads, and coverage counts the result. The summary says the review was run by hand.
  • Shares the factory's run log when given --state-file. The new reserveManualCrCliRun refuses while the lane is paused, busy or out of hourly budget. It spends an hourly slot and holds the lane's in-progress slot as a manual run with its pid, so the factory's gate waits at cli-busy rather than starting a second vendor run. It creates no card record, and a vendor rate limit or auth failure pauses the lane.
  • Housekeeping leaves a live manual run alone, even with the lane switched off. It frees the slot, still counting the hour as used, once the process is gone or more than 70 minutes past its deadline. A reused pid counts only if its command line is a review of the same PR (isManualReviewCommand).
  • Stopping it is clean. On SIGTERM, SIGINT or SIGHUP the process kills its CLI child, removes its temp worktree and frees the slot. factory:cr-cli-finish recognises a manual run and sends that process SIGTERM, not its group.
  • Docs: ADR-0037, a runbook section, and a note in dark-factory.md.

The /merge skill (in claude-skills) is updated in step with this change: when the head isn't covered, it runs review in the background, waits for a PR-bot review already under way, lets threads block as usual, and otherwise merges with a note.

Tests

  • node --test scripts/__tests__/*.test.mjs: 1678/1678 pass. New tests cover runManualReview (skip reasons, ledger refusals, a posted review, rate-limit pause, worktree failure refund, head moved, a throw or signal mid-run), the housekeeping manual branch, the gate holding at cli-busy, reserveManualCrCliRun, the manual flag surviving a save and load, isManualReviewCommand, and factory:cr-cli-finish against real processes.
  • pnpm lint, pnpm typecheck, pnpm format:check pass.
  • Dry run against live PRs: review --pr 637 --dry-run 1 returns would review; --pr 634 returns pr-merged.
  • Infra-only; no apps/ or packages/ changes.

Summary by CodeRabbit

  • New Features

    • Added a manual CodeRabbit CLI review workflow for hand-opened pull requests.
    • Reviews run in the background, post findings as review threads and summary comments, and share existing review-lane limits when configured.
    • /merge can trigger a manual review without blocking on coverage.
  • Documentation

    • Added guidance covering manual reviews, operational behavior, and the accepted design decision.

The CLI gap-fill lane only reviews factory cards, so a PR opened by
hand whose head the rate-limited PR bot skipped had no second reviewer
and /merge stopped on it.

`coderabbit-cli.mjs review --pr N --repo-root R [--state-file F]` runs
the same CLI review synchronously and posts findings the way the lane
does, so `coverage` counts them. With the factory state file it shares
the lane ledger: refuses while paused/busy/out of budget, holds a
`manual` inFlight so the factory gate waits at cli-busy, and pauses the
lane on a vendor rate limit. Housekeeping leaves a live manual run
alone and frees the slot once its process is gone; factory:cr-cli-finish
SIGTERMs it, and the process kills its CLI child and releases the lane.

ADR-0037 records the decision.

📝 Walkthrough

Walkthrough

The change adds a manual coderabbit-cli.mjs review command for hand-made pull requests. It shares factory CLI state when configured, posts manual-origin findings, handles process cleanup, and documents and tests the new flow.

Changes

Manual CodeRabbit CLI Review

Layer / File(s) Summary
Manual lane reservation and process lifecycle
scripts/lib/factory-state.mjs, scripts/lib/state-cli.mjs, scripts/lib/coderabbit-cli.mjs
Manual reviews reserve shared budget and in-flight state. Factory state checks process ownership, preserves manual records, releases lost runs, and stops the manual process with SIGTERM.
Manual review command and result posting
scripts/lib/coderabbit-cli.mjs, scripts/lib/coderabbit-review.mjs
The CLI adds review --pr N --repo-root R. It skips covered heads, runs the vendor review in a temporary worktree, handles signals and outcomes, and posts findings with manual-origin text.
Manual review and lifecycle validation
scripts/__tests__/coderabbit-cli.test.mjs, scripts/__tests__/factory-state-cr-cli.test.mjs, scripts/__tests__/state-cli-factory.test.mjs
Tests cover skip paths, lane refusals, budget handling, review posting, rate limits, moved heads, signal handling, housekeeping, command matching, and process cleanup.
ADR and operator documentation
docs/adr/0037-manual-coderabbit-cli-review.md, docs/adr/README.md, docs/features/dark-factory.md, docs/operations/factory-runbook.md
The ADR, feature description, index, and runbook describe the command, shared state, execution behavior, and operational conditions.

Priority: ⬇️ Low

Estimated code review effort: 4 (Complex) | ~45 minutes

Change: Feature

Merge Risk: 🔵 Low · up to ed9b0

The manual-review workflow is generally mergeable, but several localized cleanup, process-identification, and documentation issues should be corrected to avoid operational surprises.

- Line 26: Update runHousekeeping so FACTORY_CR_CLI=0 only winds down
factory-managed runs; check lane state before routing manual reviews to
windDownManual, leaving live manual runs active. Update the factory runbook’s
corresponding operational section to state this scope and direct operators to
factory:cr-cli-finish with the run ID to stop manual reviews.

In `@docs/operations/factory-runbook.md`:
- Line 384: Update the manual PR review precondition in the factory runbook to
state that the PR’s head has not been covered by a review, replacing the
ungrammatical wording while preserving the surrounding CLI instructions and
link.

In `@scripts/lib/coderabbit-cli.mjs`:
- Around line 1142-1143: Update windDownManual to call removeWorktree with
inFlight.worktree in the process-gone case, after confirming no manual process
still uses it. Preserve the existing lane-release and finishRun behavior, and
rely on removeWorktree’s null-path handling for records without a worktree.

In `@scripts/lib/coderabbit-review.mjs`:
- Around line 1315-1317: The isManualReviewCommand matcher must validate the
actual Node entrypoint, not independent substrings. Update isManualReviewCommand
to parse or structurally validate arguments requiring Node to execute
coderabbit-cli.mjs, followed by review and --pr matching prNum; add the
other.mjs ... coderabbit-cli.mjs example as a negative matcher and lifecycle
test, and ensure the positive lifecycle fixture executes coderabbit-cli.mjs
rather than appending arguments to node -e.

CodeRabbit CLI review — d2aa22c31385

The CodeRabbit PR bot did not review this commit, so the CodeRabbit CLI was run by hand (coderabbit-cli.mjs review) on the changes in ed9b0a5ab363..d2aa22c31385 (incremental). Outcome: ok.

Opened 0 inline threads.

1 finding not opened as threads
  • minor scripts/lib/coderabbit-review.mjs — In @​scripts/lib/coderabbit-review.mjs at line 1325, Update the Node argument validation around the loop over leading options so it accepts only the launcher’s explicit whitelist of supported Node flags, rejecting execution modes such as --test that do not invoke the CLI entrypoint. Add the shown --test invocation as a rejected fixture while preserving acceptance of valid launcher commands. (below the thread threshold)

Automated, unverified vendor findings (CodeRabbit CLI, posted by coderabbit-cli.mjs review).
