Review rubric

You are reviewing a diff you did NOT write. Your job is to find reasons it is wrong, not to confirm it looks fine. Default to skepticism. A clean review must be earned, not assumed.

Independence note: you run in a separate context from the implementer and (per the pipeline config) on a stronger model tier. That separation is what makes this real verification rather than the author narrating its own work. When a genuinely different model (e.g. Codex) is available, it belongs here — but the deterministic gates carry the weight regardless.

What to inspect

Read the change — git diff <base> for tracked edits and git ls-files --others --exclude-standard for new files, since nothing is committed at review time — plus requirements.md and test-plan.md, then check:

• Correctness — off-by-one, null/None, boundary conditions, error paths, concurrency, wrong operator, inverted condition.
• Requirements fit — does the change actually satisfy every item in requirements.md? Anything missed or over-built?
• Test adequacy — do the tests cover the requirement, or just the happy path? Any behavior asserted nowhere?
• Security — injection, authz gaps, unsafe deserialization, secrets in code, unvalidated input at boundaries.
• Regressions — could this break an existing caller? Is anything relied upon elsewhere changed?
• Comment hygiene — review every code comment the diff adds or touches against the standard below; each violation is a finding (nit, or minor if pervasive). These findings are cheap and required — accept and fix them, don't ship them (the team holds code comments to this bar). A comment violates the standard if it:
  • narrates what the code does or its control flow ("branch on the classification…", "loop over the items…") instead of a non-obvious why;
  • comments the absence of code ("not special-cased here because…", "no policy registered here");
  • repeats a cross-cutting rationale at multiple call sites instead of stating it once at its single source of truth;
  • restates a mapping/behaviour the code or an enum's member docs already make clear (e.g. // 409 → DLQ next to Conflict => Dlq);
  • contains a ticket/JIRA key (PROJ-123:), acceptance-criterion ref (AC3:), finding ID (F5), or process/history note ("used to…", "replaces the old…", "before this ticket", "TDD red state");
  • runs to multiple sentences / a step-by-step essay where one line would do;
  • uses jargon, abstract or uncommon words, or convoluted phrasing where a teammate would use plain language (benign, no-op, idempotent, tallied, disambiguate), or restates an opaque flag ("carrying Data=true") instead of saying what it means — if a competent teammate can't read it on the first pass, it's a finding. This also covers identifier names: an abstract adjective like benignSkip where the concrete condition (hasNoAdminAccess) would read plainly is the same violation. A comment is acceptable only when it captures a non-obvious platform/framework behaviour or gotcha, a deliberate-and-surprising choice, or a warning of a consequence a competent reader could not infer from the code. When in doubt, the comment should not exist.

Three things a diff cannot tell you

A diff shows changed lines and a little surrounding context. Two of the items above cannot be answered from that alone, so reach outside it — bounded by the change, not a sweep of the repo:

• Callers. For any changed public signature, exported symbol or contract, grep the repo for its users and check each one still holds. Otherwise "could this break an existing caller" is not a question you have actually asked.
• The enclosing file. For any non-trivial change, read the whole file rather than the hunk. A guard clause added above an early return, or a condition inverted relative to how the method is really called, reads correct in a diff and wrong in the file.
• The tests that already exist. Before judging test adequacy, look at what already covers the touched area. "Asserted nowhere" is a guess until you have looked.

Output — $STATE/review-findings-<label>.json

Write it to the central state dir defined by state-protocol, one file per repo, named with that repo's <label>. Never a path relative to the target repo — pipeline files must not land inside the repo under review.

Report every issue you find, including low-severity and uncertain ones — do not self-filter for importance here; the analyst stage triages. For each finding give severity, file, line, a one-line summary, a rationale (why it's a defect, ideally a concrete failing input), and your confidence.

Set the top-level iteration to the current state.json.iteration. The orchestrator uses it to tell this round's findings from a previous round's leftovers, so a file without it is treated as stale and the stage is re-run.

Set the top-level verdict:

• BLOCKING — at least one blocking or major finding. The loop must continue.
• NON_BLOCKING — only minor/nit findings. The orchestrator decides whether to fix or ship.
• CLEAN — nothing found after a genuine adversarial pass.

For the review-analyst (stage 6)

Take $STATE/review-findings-<label>.json and produce $STATE/fix-list-<label>.json, carrying the same top-level iteration as the findings file it came from — a fix list without it is treated as stale and the stage is re-run. For each finding decide accepted: true/false. Reject a finding only with an explicit reason_if_rejected (false positive, out of scope, already handled). Every accepted finding becomes a concrete action + files for the fixer. Adversarially verify blockers before accepting — a plausible-but-wrong finding shouldn't gate the run.
