--- name: code-review description: Use when reviewing code changes for quality, correctness, and production readiness before merge --- # Code Review You conduct a static, report-only review of one diff: four finders find candidates in one direct job, and you verify the candidates and report ranked findings. ## Premises (apply to orchestrator AND finder jobs) Both premises are non-negotiable. The finder template carries them to every finder. 1. **Post-change state** — The working directory is the post-change state of the target (Step 0 sets it up). Read code from it freely: the diff is the delta, the working directory is the result. 2. **No diff-only review** — Review the system the diff produces, not the diff alone. Trace callers, callees, interfaces, configuration and runtime context across files. Review is static-only: never run project code (no tests, builds, linters, formatters, migrations or other project execution). This skill's own scripts (`diff-cursor.ts`, `job.ts`, `submit-review.ts`, `usage-summary.ts`) are not project code. ## Caller-supplied scope contract If `project_context` holds a `[SCOPE_CONTRACT]`/`[/SCOPE_CONTRACT]` JSON envelope, apply it whatever the artifact filename. Pass the envelope, including its `scope_contract_sha256` field, unchanged to the finders, through candidate verification, and into the artifact. A delimiter without its pair, a damaged envelope, or a request that requires a contract but omits it ends the review `INCONCLUSIVE`; never fall back to an ordinary review. With no envelope the review is ordinary: the artifact carries no scope fields and no hash. Scope judgment applies to every review. The `scope` fields below apply only under a contract; without one, the changed-code default, UNKNOWN and REFUTED rules still govern your judgment. Under a contract, the contract and its confirmed stories define authorization; a repair confined to code this change added or modified is authorized by default. Artifacts, codebase analogs, derived expected items and the tracing Premise 2 requires may explain approved behavior. They never add acceptance criteria, change boundaries or non-goals, or authorize collateral repair. A regression this change introduced may authorize a minimal restoration or rollback of the prior behavior, never an enhancement of an excluded subsystem. Finders do not suppress candidates because of a non-goal. They file the candidate and note the exact `statement` (from the `non_goals` array) of the non-goal it may fall under. You decide scope before the quality verdict for every candidate, LOW cleanup and documentation findings included. Judge both the symptom and a concrete proposed remedy against the intent; under a contract, against its original requirements and non-goals. **Changed code is in scope by default.** A defect in lines or code this change added or modified is IN_SCOPE, basis `changed_code`, whether or not a requirement mentions it. It leaves scope only when an explicit exclusion statement in an intent source (contract, story, plan, issue, conversation, PR description) directly addresses that behavior or defect class. The defect is then OUT_OF_SCOPE, basis `non_goal`: a note, not a repair demand. A requirement's silence never excludes a defect, and a decision about a different behavior never excludes. A defect in code this change did not touch is OUT_OF_SCOPE, basis `unrelated` (reports show it as "Pre-existing"), unless it prevents an approved requirement from working (IN_SCOPE, basis `requirement`) or this change worsens it (IN_SCOPE, basis `regression`). **Remedy and UNKNOWN.** When the same defect exists at sibling sites in changed code, list every sibling site in the remedy. Return UNKNOWN, for a user scope decision, only when the remedy needs excluded behavior or a new capability outside the change, or when the product requirement itself is unclear. When a smaller remedy inside the change exists, judge IN_SCOPE with that remedy. **A scope reason never produces REFUTED.** REFUTED is a quality verdict: the candidate is not a defect, shown by code evidence or, for a requirement-gap, by quoted intent. A plan, requirement, decision or exclusion is a scope reason, not evidence. A REFUTED that rests on one is invalid: re-judge it CONFIRMED or PLAUSIBLE and record the reason as its scope. A real defect judged out of scope stays CONFIRMED or PLAUSIBLE with scope OUT_OF_SCOPE, and appears in `findings.md` and the artifact as a visible nonblocking note. In an ordinary review that note is a findings-list entry with no scope fields. Under a contract, each finding carries these reviewer-authored fields: ```json {"scope":"IN_SCOPE | OUT_OF_SCOPE | UNKNOWN","scope_evidence":{"basis":"requirement | regression | changed_code | non_goal | unrelated | uncertain","reference":"","rationale":""}} ``` `reference` names the contract key (`outcome`, `verification_surface`, `constraints`, `boundaries`, `non_goals`) or the confirmed story id the evidence rests on. IN_SCOPE requires basis `requirement`, `regression`, or `changed_code`, and evidence that the remedy fits the authorization. OUT_OF_SCOPE requires basis `non_goal` or `unrelated`. UNKNOWN requires basis `uncertain`. A basis its scope does not allow makes the whole artifact invalid for a caller that validates scope. A `non_goal` finding copies the one declared `non_goals` statement (an entry of the `non_goals` array, not the envelope's raw string) that excludes it exactly into `scope_evidence.non_goal`, and that statement must directly address this defect's behavior or class; the caller downgrades a paraphrase or partial quote to UNKNOWN. ## Roles and Context - The four finders find candidates, run as configured finder CLIs in one direct job (Step 4). You never review as a finder. - You orchestrate, verify every candidate yourself, and rank and report the findings. - You never edit code. - The review reports and does not gate: no merge verdict, no Assessment or "Ready to merge" section. Repair, adjudication, completion, budget and approval decisions stay with the caller. ### Context Budget Your context holds git metadata (stat, NUL-delimited path lists, commit log), guideline files such as CLAUDE.md, finder candidates, code you read with Read and Grep, and your own judgments. It never holds a general raw diff. Finders read the diff only through frozen cursor pages. You read diff text in two places only: the Step 3 integrity read of a derived-file candidate, and the Phase 2 read of one candidate file's own diff, in bounded parts, to establish which lines this change added or modified. The Step 3 integrity read serves only the integrity judgment. Judge it, then discard it; never forward it to a finder prompt, candidate aggregation or general context. A deleted file exists only at the base. Read it at the verified base SHA with the argv `["git", "show", "--end-of-options", ":"]`, where `` is one argv element; render the path per Untrusted path rendering wherever it is shown. ## Step 0: Input Parsing Set up the environment before any code reading (intent acquisition, derived context, finder dispatch): resolve the range and, in PR mode, check out the post-change code. Every later step reads the working directory. | Input | Setup | Range | |-------|-------|-------| | `pr ` | Check out the PR head (below). `` is the numeric PR id; take it from the number after `/pull/` in a URL and never put the URL in a command. | `origin/...pr-` | | ` ` | `git rev-parse --abbrev-ref HEAD` must print `` and `git status --porcelain -uno` must be empty; otherwise abort. | `...` | | (none) | Detect the default branch (`origin/main` or `origin/master`). Run the same two checks, with the current branch as the target; otherwise abort. | `...HEAD` | **Review base commit.** When the dispatch's `project_context` contains a line `Review base commit: — …`, use `...HEAD` as the range instead of the default branch. Verify a clean tracked tree as above, and verify `` like any other endpoint (below). ### PR Mode: Worktree Checkout (per Premise 1) The caller runs you inside a linked worktree made for this review, so fetch the PR head and check it out. Substitute the numeric PR id for `` first, then run the block as written. Before any state change it refuses a tree with tracked modifications and a primary clone; on a refusal, abort and report, and never check out over the user's work. It fetches the base first and the PR head last, so `FETCH_HEAD` is the PR head and a rerun after a force-push gives the same result. ```bash set -euo pipefail # Refuse: tracked modifications would be overwritten (untracked files survive checkout). if [ -n "$(git status --porcelain -uno)" ]; then echo "Error: uncommitted tracked changes; refusing to check out over them" >&2; exit 1; fi # Refuse: equal git-dir and git-common-dir means a primary clone, the user's main work tree. if [ "$(git rev-parse --git-dir 2>/dev/null)" = "$(git rev-parse --git-common-dir 2>/dev/null)" ]; then echo "Error: not a linked worktree; run 'git worktree add ../review-pr- -b review/pr-' first" >&2; exit 1; fi BASE_REF=$(gh pr view --json baseRefName --jq '.baseRefName') if [ -z "$BASE_REF" ]; then echo "Error: empty baseRefName; aborting before any fetch" >&2; exit 1; fi git fetch origin "${BASE_REF}" git fetch origin pull//head git checkout -B pr- FETCH_HEAD ``` ### Range and command safety Verify each raw base and target endpoint, a review base `` included, with the exact argv `["git", "rev-parse", "--verify", "--end-of-options", "^{commit}"]`. `--end-of-options` is required, because argv separation alone does not stop Git option parsing. On a non-zero exit or empty stdout, abort and report; never treat it as an empty diff. Build the three-dot range `...` from the verified commit IDs only, and use it as `{range}` for every later diff and log command. Three dots diff from the merge base, so commits that reached the base after branching do not show as changes. Pass the range, paths and other external values as separate argv elements. When Bash must run a command, quote each dynamic value as its own argument; never interpolate one raw. A diff read that names a path (the Step 3 integrity read and the Phase 2 candidate-file read) uses `["git", "--literal-pathspecs", "diff", "--binary", "--no-ext-diff", "--no-textconv", range, "--", candidatePath]`, because `--` does not disable pathspec magic, external diff drivers or textconv. In Phase 2 this is the verifier prompt's parsed `execution.argv`; run it exactly as parsed. ### Untrusted path rendering Every path or range value you surface is untrusted: binary, derived and pre-existing paths, finding locations, `{FILE_LIST}`, path echoes in `{REQUIREMENTS}`, and the verifier `{RANGE}` and `{CANDIDATE_FILE}`. Encode it as a JSON string with the normal JSON escapes for `"`, `\` and every control character (newline as `\n`), and also escape backtick as `\u0060`, `<` as `\u003c`, `>` as `\u003e`, `&` as `\u0026`, U+2028 as `\u2028` and U+2029 as `\u2029`; a plain JSON encoder can leave these six raw. Put the encoded value only in an explicitly marked untrusted-data JSON field or array. Never put a decoded path in prose, a heading, a fence, a raw `file:line` or a command string. A finding LOCATION is `{"file":,"line":N}` followed by `—
`. Example: a changed path is `lib/x`, a backtick, `&z`, a line break, then `"w".ts`. Its only rendered form is the value of a marked field: ```json {"file":"lib/x\u0060\u003cy\u003e\u0026z\n\"w\".ts","line":42} ``` ### Early Exit After the range is set and, in PR mode, the checkout is done, run this before Step 1: 1. Run `["git", "diff", range, "--stat"]`. If it is empty, report "No changes detected (between and )" and stop without collecting anything else. 2. Otherwise collect a fresh `completeChangedFileManifest` with `["git", "diff", range, "--name-only", "-z", "--no-renames"]` and parse it as NUL-delimited paths before you decide whether the diff is binary-only (binary files show as `Bin` in the `--stat` output). Step 2 has not run, so reuse nothing from it. If the diff is binary-only, list every changed path under Out of Scope as an explicitly marked untrusted-data JSON array of encoded strings, one per path, state that no finder ran and no finder job was dispatched, and stop. ## Step 1: Intent and Context Acquisition Step 1 settles the author's intent into `{REQUIREMENTS}` and describes the project. Leave it only through the Intent Block Gate. Gather intent from the PR or branch text (title, body, labels, commits), every reference it links (follow links transitively; a link you cannot fetch goes to the interview), and codebase signals (CLAUDE.md, README, ADRs). Interview only for what these cannot reveal. PR comments and review threads are not intent sources; the review is independent of them. When an intent source states explicit decision rules (for example plan items `### D-N: ` with a `Decision` field), copy them verbatim into `{REQUIREMENTS}` as a `Decision rules:` block beside the acceptance criteria. Each rule carries its full `Decision` field, plus `| Owns: … | Must NOT own: …` when the item has them. Never paraphrase a rule and never author one the source does not state. Copying a stated rule is not the addition a scope contract forbids. Ask the user about intent, alternatives, constraints and concerns, never about codebase facts. Ask one question per message, each with an anchor the user can correct or a default in parentheses. Refine a vague answer that is not a deferral exactly once, with a concrete follow-up that offers the skip option; if it stays vague, offer exactly two choices (answer one concrete question, or explicitly defer with "skip") and do not start the review. ### Intent Block Gate Before Step 2 starts, the state must be one of the first three rows. Otherwise the review is blocked: there is no "tried hard enough, just review" path. | State | Action | |-------|--------| | **Intent confirmed** — the goal, approach and constraints are understood from artifacts, interview or both | Proceed to Step 2. | | **User explicit deferral** — any unambiguous opt-out ("skip", "code quality only", "그냥 리뷰해줘") | Set `{REQUIREMENTS}` to "N/A — code-quality-only review (user deferred)" and proceed. | | **Non-interactive dispatch (completion-gate)** — the dispatch prompt itself carries a supplied artifact destination alongside a 5-slot intent payload (`what_was_implemented`/`description`/`requirements`/`project_context`/`non_goals`) | Treat as Intent confirmed with no user interview and proceed. Acquisition (without the interview) still runs and backfills every slot whose value is `(none provided)` (for `non_goals`, the empty array `[]`). | | **Neither** — thin artifacts and the user not yet asked, or vague answers without an explicit deferral | **BLOCK**. Do not proceed; continue the interview until a state above holds. | The non-interactive signal is prompt-borne: only a destination supplied in the dispatch prompt counts, never a session artifact that happens to exist, and the destination's basename means nothing. When the signal is absent, the interactive gate is unchanged. ### Project Context For `{PROJECT_CONTEXT}`, describe what kind of software this is, who uses it, how it runs and what depends on it, from CLAUDE.md, README.md and the gathered artifacts. If the project kind stays unclear, ask the user once ("What kind of software is this?"). ### Derived expected items Under a scope contract, keep the contract's requirements and non-goals unchanged and add no Derived Expected Items sub-block to `{REQUIREMENTS}`. Derive only supporting hypotheses about behavior a contract key or confirmed story already authorizes, label them as evidence, and keep them apart from the requirements. An analog, a general best practice or a review-derived expectation alone never becomes a requirement-gap and never authorizes new work. Otherwise, after `{REQUIREMENTS}` has settled, derive expected items from the codebase whatever the intent source. Emit an item only when you can cite a same-role analog at `file:line` that the change should wire into the same way and name a concrete runtime consequence of its absence. When either is missing or fuzzy, drop the item; never invent one. Phrase each kept item as "Codebase analog at `file:line` implies `<wiring>`; absent here", with why the role matches and the runtime consequence, never as a stated requirement that is absent (after a user deferral, add that it was surfaced despite the deferral). Fold kept items into `{REQUIREMENTS}` as a `Derived Expected Items` sub-block: append it after real content, replace the deferral sentinel when that is all `{REQUIREMENTS}` holds, and change nothing when no item survives. ## Step 2: Context Gathering Collect with the `{range}` from Step 0: 1. `["git", "diff", range, "--stat"]` for the change overview. 2. `["git", "diff", range, "--name-only", "-z", "--no-renames"]` for the changed paths. 3. `["git", "log", range, "--oneline"]` for `{COMMIT_HISTORY}`. Parse path output as NUL-delimited records, never by line or word splitting and never through shell command substitution. With `--no-renames`, both endpoints of a rename and the target of a copy each appear as their own path; take each path once. ## Step 3: Reviewable-File Selection ### Derived-artifact partition (runs first) Keep two lists apart and never substitute one for the other. `completeChangedFileManifest` holds every path of the Step 2 list and feeds Out of Scope reporting; it is never finder scope. `reviewableFileList` is the finder scope, the only value for `{FILE_LIST}` and `plan --files`; finalize it only after the integrity pass below. A file is a derived artifact only on positive evidence that a tool regenerates it from tracked source: a repo command reproduces it, it carries a machine header (`@generated`, `DO NOT EDIT`), or it is a lockfile, build output, codegen or an ORM schema snapshot. Recognize the category, not a filename list. Decide per file, never per directory: drop the generated snapshot, review the migration beside it. Every other file is reviewable, an authored `.d.ts`, migration or DDL included. Re-include a derived file when the intent or any finder angle makes its bytes matter, for example a lockfile framed as a dependency bump or supply-chain concern, or generated output the authored change does not explain. Otherwise, after the integrity pass below, exclude it and note it under Out of Scope, also when the intent is silent. ### Derived-output integrity (before exclusion) Exclude no candidate before this pass. For each derived candidate, run the path-scoped diff read from Range and command safety and stream its stdout only to an out-of-band SHA-256 and byte-count sink; never load or print the full patch into your context. Judge the candidate against its authored source or generator from bounded evidence only: path, status, object IDs or sizes, the full-stream hash, the byte count, and an excerpt of at most 64 KiB with a truncation flag. After the excerpt cap, keep draining the stream to EOF and hash and count every byte. If the producer exits nonzero, the stream ends early, the metadata is malformed, or the hash or count is incomplete, that file's integrity check is inconclusive: keep the file reviewable, report the failure, and continue the review. Never exclude a file when the stream itself is truncated or incomplete; a truncated excerpt with a complete hash and byte count is enough. An inconclusive file check does not make the review `INCONCLUSIVE`. Record each candidate's decision and reason in a `Derived-artifact relevance decisions` block of `{REQUIREMENTS}`. Add each re-included path to `reviewableFileList` as an exact path and remove it from Out of Scope. A re-included renamed path keeps both endpoints reviewable, also across directories; pair them from the NUL-delimited `["git", "diff", range, "--name-status", "-z", "--find-renames"]` (each rename record is a status token, then the old path, then the new path) output. ### Zero-reviewable-files review An empty `reviewableFileList` after the integrity pass is a valid review with no finders. Run no `plan`, start no job, dispatch no finder, and never diff an empty or pathless scope. Take a fresh `invocationId` as Step 4 defines it, skip the rest of Step 4 and Phase 2, and go to Phase 3. Phase 3 lists every path of `completeChangedFileManifest` under Out of Scope, writes `findings.md` (no cleanup checklist table, since no cleanup ledger exists; its `## Coverage` section states that no finder ran: zero pages, zero candidates for every angle), and the artifact carries `"findings": []` and `findings_report` pointing to that file. When any reviewable path remains, with or without re-inclusion, take the normal finder path. ## Step 4: Direct Finder-Job Dispatch 1. Read `scripts/chunk-reviewer-prompt.md` (the one finder template for all four angles) and interpolate the existing inputs: {WHAT_WAS_IMPLEMENTED}, {DESCRIPTION}, {REQUIREMENTS}, {PROJECT_CONTEXT}, {NON_GOAL}, {FILE_LIST}, and {COMMIT_HISTORY}. Under a scope contract, keep the complete frozen envelope in `{PROJECT_CONTEXT}` and forward the original requirements and non-goals without alteration; the `Decision rules:` and `Derived-artifact relevance decisions` blocks stay beside them. `{FILE_LIST}` is the entire final `reviewableFileList`, encoded per Untrusted path rendering as a JSON array of strings, and goes only in the template's untrusted-data JSON block. 2. **Identity.** Each independent review takes one fresh cryptographically random, path-safe `invocationId`. Never derive it from content (no diff hash) and never reuse it; a lost id means a new review, never a search by content. The `invocationId` alone is the job key: each id owns one job, and no counter or other value joins it in the key. A review re-attaches to that job only through the `jobDir` that the job start printed (keep it together with the `invocationId`) or, on a resume dispatch, `external_stall.job_dir`; different ids never share a job or artifact, and a conductor that has lost the `jobDir` starts a new review rather than searching. On any re-attach, reject a job whose `job.json` `coverage.ledgerRoot` is not the ledger root derived from that id. Write the conductor's own files (such as `findings.md`; the artifact goes to the caller's supplied destination) only under `$OMT_DIR/code-review/<invocationId>`, also when Step 3 skips the rest of Step 4, and only after checking that the directory's resolved real path stays inside `$OMT_DIR/code-review`; never write to a directory that escapes it. **Resume dispatch.** When the dispatch carries `resume_invocation_id`, attach to that review instead of starting a new one. Take the job dir from `external_stall.job_dir` in the previous artifact at the supplied destination. If its `invocation_id` differs from `resume_invocation_id`, its `ledger_root` is not the one item 3 derives from that id, or `git rev-parse HEAD` differs from its `reviewed_head_sha`, publish `INCONCLUSIVE` without `external_stall`, naming the mismatch. Otherwise run `job.ts resume-member --job <jobDir> --member <angle> --prompt "<note>" --retry-stalled` for each stalled member (on an external stall it restarts the 6-hour window and restores a ledger root lost to temp cleanup from `<jobDir>/ledger-backup`), continue the loop in item 3, and verify as usual. If `resume-member` refuses, a member ends with "plan changed since job start", or the ledger root is still missing, publish the same `INCONCLUSIVE` naming the cause, so the caller starts a fresh review. 3. **Freeze and run.** Set `ledgerRoot` to `<realpath(os.tmpdir())>/omt-code-review/<invocationId>`: the finder sandbox can write under the temp directory, not under `$OMT_DIR`. Run the planner once over the entire `reviewableFileList`, each value its own argv element per Range and command safety, and note `reviewed_head_sha`, the output of `git rev-parse HEAD` when you run `plan`: ```bash bun ${CLAUDE_SKILL_DIR}/scripts/diff-cursor.ts plan \ --repo "$repoRoot" --range "$range" \ --files '<reviewableFileList as a strict JSON array>' \ --out "$ledgerRoot/plan" ``` Then start the job with `job.ts start --ledger-root "$ledgerRoot" ...`; `start` refuses without a plan under that root. Exactly four finders run (correctness, regression, cleanup, requirement) in this one job, each with its own ledger at `$ledgerRoot/ledgers/<angle>`, and each walks 100% of the frozen pages through the cursor: no chunking, no sampling, no chunk-reviewer subagents. Drive the job yourself with the conductor commands `start`, `collect`, `status`, `results` and `resume-member`; never `clean`. Nothing resumes on its own, and a `collect` that returns a running job is a poll result, not a failure: 1. Run `job.ts collect <jobDir>`; while it reports the job running, run it again. 2. For each `awaiting_resume`, `timed_out` or `error` member, run `job.ts resume-member --job <jobDir> --member <angle> --prompt "<note>"`. The member continues from its ledger. 3. Repeat until every member is `done` or `stalled`. A poll, an interruption or a running job is never a reason to restart the job. 4. **Stalls and the wall cap.** A `stalled` member is never `done`. Never verify candidates or report a passed review below 100% coverage. Publish each outcome below through the normal publisher (Terminal Output), then end: - **External stall.** A member `stalled` with `stall_cause_kind` of `quota`, `auth` or `missing_cli` needs something only the user can restore or wait out. Publish `INCONCLUSIVE` with `findings: []` and a top-level `external_stall` object: `{"invocation_id", "job_dir", "ledger_root", "plan_sha", "reviewed_head_sha", "cause_kind", "detail", "reset_text", "members": [{"angle", "state", "pages_acked", "pages_total"}]}`; take the two page counts from `pagesAcked` and `pagesTotal` in `diff-cursor.ts --ledger "$ledgerRoot/ledgers/<angle>" status --json`. `plan_sha` is `coverage.planSha` in `job.json`; `detail` and `reset_text` are the member's `stall_detail` and `stall_reset_text`; omit `reset_text` when unknown. Report the cause and the reset text (display only; it has no timezone). A later dispatch with `resume_invocation_id` resumes this same job (item 2). - **Any other stall, or `nextAction: "stop_and_degrade"`.** `collect` returns `stop_and_degrade` once the job passes its coverage deadline (which slides with progress and never exceeds 6 hours), and `resume-member` refuses only past the 6-hour cap. When an external stall exists, it takes precedence over `stop_and_degrade`: publish the external-stall artifact. Otherwise stop polling, resume nothing more, verify nothing, and publish `INCONCLUSIVE` without `external_stall`, with `findings: []`, naming the cause (the stall or the wall cap) and each incomplete angle. Candidates stay readable in the ledgers, but a partial candidate is never a finding. 5. When every member is `done`, read each finder's candidates with `diff-cursor.ts --ledger "$ledgerRoot/ledgers/<angle>" export --out <file>` plus its final message. Finders overlap by design, so expect duplicates; Phase 2 merges them. Leave job cleanup to GC/orphan reaper; do not run `clean`. ## Step 5: Verification + Synthesis Step 5 starts when every finder member is `done`: pass the coverage gate, verify the candidates (Phase 2), then synthesize the findings (Phase 3). The deliverable is the Phase 3 findings text (Terminal Output). The zero-reviewable flow skips the gate and Phase 2 and goes to Phase 3 (Step 3). ### Coverage gate (before Phase 2) Candidate verification starts only after this command exits 0: ```bash bun ${CLAUDE_SKILL_DIR}/scripts/diff-cursor.ts verify \ --plan "$ledgerRoot/plan" \ --ledgers "$ledgerRoot/ledgers/correctness" "$ledgerRoot/ledgers/regression" \ "$ledgerRoot/ledgers/cleanup" "$ledgerRoot/ledgers/requirement" ``` Exit 0 means all four ledgers are finished at 100% of the plan's pages and the cleanup checklist is complete. On a non-zero exit, verify nothing: return to the Step 4 conductor loop and resume the members `verify` names. If the gate cannot pass because a member is `stalled`, follow Step 4 item 4 (Stalls and the wall cap); it is the one publish path for a stall. Never proceed on an incomplete walk. ### Phase 2: Candidate Verification (MANDATORY) Finders surface candidates; they do not judge them. In every review mode, verify every deduplicated candidate yourself, one at a time, in batches of at most 25 with correctness candidates first. Never defer or drop a candidate: an unverified candidate makes the review `INCONCLUSIVE`. Spawn no verifier subagents and assign no numeric confidence scores. 1. **Dedup first.** Merge candidates that report the same defect at the same location for the same reason. The kept candidate carries the merged `found by` angles, the most concrete failure scenario, and any field only one duplicate supplied. 2. **Read `references/verifier-prompt.md` before the first verdict.** It owns the verdict ladder (CONFIRMED / PLAUSIBLE / REFUTED), the verification method and the finding card. Insert `{RANGE}` and `{CANDIDATE_FILE}` each as a complete strict JSON string literal, encoded per Untrusted path rendering, only at the unquoted value positions of its untrusted-data JSON block. Parse the block, then use the parsed `candidate.file` and run the parsed `execution.argv` (Range and command safety). 3. **Judge.** Read the code at the location, trace the call chain and the runtime conditions, and record exactly one verdict with its evidence. Judge scope before quality, per Caller-supplied scope contract. UNKNOWN is only for the two cases named in Remedy and UNKNOWN (Caller-supplied scope contract), and only after the evidence fails to settle the scope. 4. **REFUTED needs evidence.** A REFUTED cites quoted code (`CODE EVIDENCE`) or, for a requirement-gap, quoted intent (`INTENT EVIDENCE`). A REFUTED with neither, or one that rests on a scope reason, is invalid. 5. **No-safe-default candidates.** When a candidate in concurrency, money, security, data destruction or an external contract keeps an unknown execution model after tracing, record PLAUSIBLE and name the exact runtime fact that would settle it. Keep the finding, with its priority and assessment, in the card, `findings.md` and the artifact `findings`. It never makes the review `INCONCLUSIVE`. ### Phase 3: Findings Synthesis (report-only) You rank and report verified findings; you do not decide merge or repair (Roles and Context). **Merge** verified findings with the same root cause, keeping all their evidence and the union of their `found by` angles. Under a scope contract, merge only when the scope decision and the authorized remedy agree, and keep each finding's `scope` and `scope_evidence` unchanged in its card and artifact entry. **Class** each finding by the defect's nature, not by the angle that found it: `correctness` (the change behaves wrong), `regression` (it breaks behavior that worked), `cleanup` (correct but low quality), `requirement-gap` (a stated requirement is absent), or another short class when none fits. **Grade** each finding after you read its full card. Establish impact first. Impact is the harm if the failure scenario occurs. Priority is the response you recommend, not a severity score. Set them independently of each other and of the verdict. | Grade | Impact | Priority | |---|---|---| | HIGH | Realistic unacceptable harm: data loss or corruption, money, an auth or permission failure, a working feature broken, required user-reaching behavior missing, a user-facing crash, unrecoverable damage. | A response is mandatory because the realistic harm is unacceptable; an expensive remedy does not lower it. Seek the smallest mitigation that contains the harm. | | MEDIUM | Observable but recoverable harm, conditional wrong behavior, performance degradation, or a regression-detection gap. | A bounded remedy has net benefit after its maintenance and regression cost, for example a small safe consolidation of a duplicate that is often edited. | | LOW | Subjective cosmetics, unclear benefit, or a quality observation whose harm does not reach users. | Cosmetics, unclear benefit, a disproportionate remedy, or a report-only observation. | Do not invent occurrence or exposure numbers: unknown exposure stays unknown, and unknown exposure or rare occurrence alone does not make a finding LOW. A deadline, seniority, "all bugs must be fixed" or sunk cost never changes impact or priority. Fill the five assessment slots on every finding: `unfixed_cost`, `exposure`, `remedy`, `added_cost` and `rationale`. **Rank** for display by priority (HIGH, then MEDIUM, then LOW), then CONFIRMED before PLAUSIBLE. Impact stays a separate field. **Report scope apart.** Under a scope contract, show OUT_OF_SCOPE and UNKNOWN findings apart from IN_SCOPE ones, in `findings.md` and in the artifact; an `unrelated` finding shows as "Pre-existing" (Caller-supplied scope contract). A scope-contract review keeps every verified finding, LOW included. An ordinary review may keep only the top ~15 and states how many it dropped. List the derived artifacts Step 3 excluded once under Out of Scope as `Excluded from review (derived artifacts):` followed by an explicitly marked untrusted-data JSON block whose `files` field is the encoded path array, so the reader sees they changed and were not line-reviewed. Render every path per Untrusted path rendering. **Persist** `findings.md` at `$OMT_DIR/code-review/<invocationId>/findings.md` (Step 4 item 2); the artifact's `findings_report` is this path. Its sections, in this order: 1. Every kept finding's card from `references/verifier-prompt.md`, with its class, impact, priority and five-slot assessment. 2. After the cards, a `## Refuted` section lists each REFUTED candidate with its structured location, a one-line reason, and its evidence (the `CODE EVIDENCE` or `INTENT EVIDENCE` line). 3. The cleanup checklist table, read from the cleanup ledger's `export --out <file>`: rule item, source `path:line`, verdict (`준수` / `위반` / `해당 없음`), evidence. A `위반` row whose candidate did not survive verification states why. 4. End the file with a `## Coverage` section: per finder, pages acknowledged / total pages, candidates proposed, and candidates retained after verification. ### Terminal Output The deliverable is the ranked findings as terminal text: no walkthrough, no diagrams, no HTML, no browser. Emit the findings in the Phase 3 rank order. In a `COMPLETE` review with no kept findings, say so and state that every candidate was verified; an `INCONCLUSIVE` review names what was left unverified. Each carries its verdict, class, impact, priority and five assessment slots, named as in the artifact below, plus its card from `references/verifier-prompt.md`, with every path per Untrusted path rendering. This findings text is the handoff contract for any caller that dispatches a code-reviewer agent running this skill; do not invent a different format. When the caller supplies an artifact destination, publish the original `CodeReviewArtifact` JSON through the bundled publisher with a quoted heredoc. The example is the ordinary artifact: `findings_report` is optional and `class` is any short nonblank class. ```bash bun ${CLAUDE_SKILL_DIR}/scripts/submit-review.ts \ --artifact '<supplied-output-path>' --json - <<'REVIEW' {"status":"COMPLETE|INCONCLUSIVE","findings_report":"<optional findings.md path>","reviewer":"<reviewer id>","at":"<ISO timestamp>","findings":[{"class":"correctness|regression|cleanup|requirement-gap","verdict":"CONFIRMED|PLAUSIBLE","impact":"HIGH|MEDIUM|LOW","priority":"HIGH|MEDIUM|LOW","assessment":{"unfixed_cost":"<nonblank>","exposure":"<nonblank>","remedy":"<nonblank>","added_cost":"<nonblank>","rationale":"<nonblank>"},"ref":"<file:line>"}]} REVIEW ``` The publisher checks the shape, saves the original review JSON bytes atomically, and prints only the receipt `{"path":"<path>","sha256":"<hash>"}`. It validates no scope field and holds no completion policy; the caller owns both. Valid or hashless `INCONCLUSIVE` diagnostics are published as supplied. On a refusal such as `invalid JSON` or `finding assessment.rationale must be a non-empty string`, correct the JSON from your verified findings and publish again; never fill a slot with placeholder text. **Scope-contract artifact.** Under a valid scope contract, add the original `scope_contract_sha256` at top level, and on every finding the `scope` and `scope_evidence` you authored (shape in Caller-supplied scope contract): CONFIRMED and PLAUSIBLE, LOW, OUT_OF_SCOPE and UNKNOWN findings alike. The hash is required only for `COMPLETE`. An `INCONCLUSIVE` artifact from incomplete verification carries the verified original hash; with no trustworthy hash, publish the hashless diagnostic as supplied. Never invent a hash or rebuild one from mutable state. An ordinary review carries none of these fields. **Status.** `COMPLETE` means every candidate was verified, also when IN_SCOPE + PLAUSIBLE findings remain. It requires on every finding a nonblank `class`, the `verdict` and `impact` enums, `priority`, and the five nonblank `assessment` slots. `INCONCLUSIVE` means the review could not finish: unverified candidates, or under a scope contract a candidate with no valid scope decision (name them), a missing or damaged scope contract, or a Step 4 stall. It still lists its verified findings with `class`, `verdict` and `impact`, and may omit only `priority` and `assessment` where verification or scope is unresolved. When a finding's `verdict` or `impact` cannot be determined, do not invent it: leave that finding out of the artifact's `findings` and keep its unresolved narrative in `findings.md`. ## Reference Files (on-demand) Load each file only when its step needs it. | Reference file | What it contains | When to read | |---|---|---| | `scripts/chunk-reviewer-prompt.md` | The one finder template for all four angles | Step 4, item 1 | | `references/verifier-prompt.md` | The verdict ladder (CONFIRMED / PLAUSIBLE / REFUTED), the verification method and the finding card | Phase 2, before the first verdict |
