Document CodeRabbit review failure modes and recovery - #122
Conversation
Add a portable comenq-coderabbit skill and linked recovery reference for queue routing, incomplete inspections, stale rows and approvals, coverage claims, duplicate findings, and candidate-bound review evidence. Include source references, a scoped handoff template, twelve offline rehearsal scenarios, and explicit installation-authority boundaries. Do not copy deployment-specific hosts, credentials, or identity settings. Validation: Markdown parsing, YAML front matter, relative links and anchors, five shell-example syntax checks, and git diff --check passed locally. Full repository CI, markdownlint-cli2, and typos were not run locally.

Add a users' guide section for the queue-based CodeRabbit review workflow: its purpose, install path, queue commands, authorized reply boundary, and links to the skill and its references. Include the review-lifecycle state diagram with a descriptive figure caption. Signpost the new skill in the migration guide with the authoritative-version and rollout requirement, and mention the skill workflows from the README. Add tests/test_comenq_coderabbit_skill.py, which holds the document contract across the skill, its references, and the guides, and encodes the documented dispositions for representative rehearsal cases. Negative controls show each contract rejects a removed rule, and every classification cites the skill sentence that states it. Co-Authored-By: Claude Code <noreply@anthropic.com>

The finding-disposition rule read "the finding is valid but its proposed implementation is wrong", which is harder to parse than the intended contrast. Insert the comma so the clause boundary is explicit. Co-Authored-By: Claude Code <noreply@anthropic.com>

Add full numpy-style documentation to classify.
Add a Parameters section documenting observation and a Returns section documenting the disposition string. classify is a public function, not a private helper. The path instructions require full structured docs for public interfaces; a single-line-plus-notes summary does not meet that bar.
As per path instructions, "Docstrings must follow the numpy style guide. Use a single-line summary for private functions and methods, and full structured docs for all public interfaces."

One 710-line test module carried three unrelated contracts at once: the document contract, the offline rehearsal cases, and the decision model. Split it so each module answers one question, and strengthen the contracts while doing so. - `comenq_coderabbit_support` holds the shared Markdown helpers and the repository paths the contract tests read. - `comenq_coderabbit_contract_data` holds the verbatim required content, now covering the delegation and safety rules as well: 21 rules rather than 12, the five named agent roles, and each rehearsal scenario's required semantics rather than its number alone. The README signpost gains a contract assertion and a negative control. - `comenq_coderabbit_decisions` holds the disposition model, labelled an executable specification rather than behavioural coverage. Each guard is now a named predicate and the precedence lives in one ordered table, with every condition and disposition preserved. - `test_comenq_coderabbit_rehearsal` requires each of the 17 documented scenarios to keep the claims that make it a check, and pins the ten recorded rehearsal cases, their expected dispositions, and the skill sentence each classification cites. - `test_comenq_coderabbit_properties` generates review states across every observed surface and asserts that no blocked state reaches merge eligibility, that a failing integration job is reported independently, and that the documented guard order stays stable. - `test_comenq_coderabbit_install` exercises the installer's real `copy_skills` at its boundary under a temporary HOME, asserting that both agents receive `SKILL.md` and its references, and that a missing source directory fails loudly. - `test_comenq_coderabbit_skill` keeps the document contract and its negative controls, now parametrized over every required rule, heading, and named role. Assertion messages name the disposition they expect, so a failure is diagnosable without reading the fixture. Co-Authored-By: Claude Code <noreply@anthropic.com>

`data/typos-oxendict-base.toml` corrects the phrase "hand-written" to "handwritten" in prose, and CI flagged the property tests' module docstring for using the former. The earlier local spelling run reported a false green: the six new test modules were still untracked at the time, and the check only sees tracked files, so it scanned none of them. Re-running the gate against the committed tree reproduced CI's output exactly, at the same line and column, confirming the violation was real rather than an environment difference. A docstring word only; no behaviour changes. Co-Authored-By: Claude Code <noreply@anthropic.com>

Summary
Add the September implementation-postmortem lessons to the
comenq-coderabbitworkflow as an installable, portable skill in this repository.Repository-location note:
skills/comenq-coderabbitdid not exist on helper-scriptsmainat base065863ab6b86bd97f7bf9254ec45b1ee28bebe2d. The existing deployed skill is maintained separately. This PR adds the requested distribution here rather than modifying that other repository or copying its deployment-specific hosts, credential paths, or posting identities. The installation section requires an explicit choice of authoritative skill version before rollout; installer ordering must not silently combine different copies.Changes
skills/comenq-coderabbit/SKILL.md: queue-first full reviews/retries, authorized focused replies, candidate-bound evidence, complete retrieval of review surfaces, explicit convergence/andon conditions, installation boundaries, and agent-team verification/remediation guidance.references/failure-modes-and-recovery.md: ten incident-derived cases, each with the recorded failure, recommended recovery, and the evidence needed to consider recovery complete.references/evidence-and-rehearsal.md: an evidence handoff, focused-response and reconciliation templates, seventeen offline rehearsal scenarios, and source PR/discussion references.The recovery cases cover wrong request routing and duplicates; clone/service failures; stale pre-merge tables; Rustdoc versus runtime coverage; unsupported behavioural claims; valid findings with invalid remedies or missing tests; stale
CHANGES_REQUESTED; rebased or subsequently amended candidates; unavailable reviewers/unmeasured analysis; and failures in post-merge integration.Important distinctions are explicit: comment delivery is not review completion; no findings after a clone failure is not a clean review; resolved threads are not approval; an old review is not a new-head review; a green PR is not successful integration. Focused replies should resolve stale rows without wasting full-review requests, but must not conceal missing required inspection or bypass branch protection.
Follow-up: agent teams and reconciliation templates
Commit
51aad555f46342dee23219de6d60e783a31a3934incorporates the requested guidance and preserves both supplied templates verbatim.Five additional documented rehearsal scenarios cover delegation, small batches, codemods and validation, warning reconciliation, and uncertain comments with unavailable codegraph analysis. The follow-up modifies only the skill and its evidence/rehearsal reference; the incident-source inventory and failure-mode reference are unchanged.
Follow-up: user-facing documentation and contract tests
Commit
a764add2721d070af6f0089aa4749135c31e01ffaddresses the pre-merge findings on this PR.docs/users-guide.md: aCodeRabbit reviews via comenqsection covering theskill's purpose, its
install-skillsinstallation path, the queue commands,the authorized reply boundary, and links to
SKILL.mdand both referenceguides. It carries the requested review-lifecycle state diagram, followed by
a figure caption that states the same content for readers who cannot see the
diagram.
docs/migration-guide.md: aCodeRabbit review skillentry signposting thenew skill and stating the authoritative-version and rollout requirement.
README.md: a brief signpost to the installed skill workflows from the quickstart.
tests/test_comenq_coderabbit_skill.py: the document contract across theskill, its references, and the guides, plus executable dispositions for ten
representative rehearsal cases: clone failure against a clean review,
unknown coverage under approval, a redundant pending request,
undispositioned rows, stale
CHANGES_REQUESTED, a replayed candidate, acapped inner comment page, failing integration, and non-green required
checks. Negative controls mutate each document in memory and assert the
contract rejects the removed rule, so deleting a rule fails CI; every
classification cites the skill sentence that states it.
The workflow is prose, so the tests exercise the documented decisions and their
grounding, not live queue, reviewer, or GitHub behaviour. They do not claim that
an agent follows the skill.
Evidence basis
The supplied
postmortems-20260908.md, especially:The reference guide links the original public PRs and relevant discussion comments. Historical statuses/counts remain historical evidence; unproven root causes and recovery chronology are not strengthened into claims. Queue examples follow the managed interface in the existing deployed skill and explicitly require checking installation compatibility. The added delegation policy and two templates are the user's requested follow-up guidance, not additional claims about what the historical agents did.
Validation
Initial three-file addition
