review

review is a skill for Claude Code from anton-abyzov/specweave. It costs 45 tokens per session (1,180 once invoked), scanned A, original, MIT.

An independent, adversarial check of an increment's specification, code changes, and surrounding code. Every reported problem must point to the exact file and line and be checked again.

In plain words
What is it for?
Use it to review correctness, security, and compliance with the specification, with either one review pass or three focused review lenses.
Why use it?
It catches concrete failures that the person who wrote the code may overlook before the change reaches users.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

sw-review: adversarial review with citations

A fresh reader hunts for real failures in the increment's diff, cites path:line for each, re-checks every claim, and writes .specweave/increments/<id>/reports/review.md. This is also the quality check: its verdict says whether the increment is ready.

Non-negotiables

  • Fresh context. The session that wrote the code never approves it. Use a new session, a subagent if your tool supports them, or another model (below). If you wrote this code here and cannot get a fresh context, say so in the report.
  • Every finding cites path:line and a concrete failure: input or state leads to wrong output, a crash, a hang, data loss or a leak. "Consider refactoring" is not one.
  • Re-verify. Re-open the lines and, where a test can show it, run one. Drop what does not survive; mark what you could not prove as plausible.
  • Severity is critical, high, medium or low. Critical and high block the close.
  • At most 5 nits, in one line at the end.

Steps

  1. Evidence first. specweave verify (or its existing reports/verify.md): red tests, lint or build are findings before any reading.
  2. Scope. Read spec.md (ACs, Approach, the tasks' Files) and review that diff, not the repository: git diff $(git merge-base HEAD origin/HEAD)...HEAD -- <Files>.
  3. Pass, in this order: correctness (logic, error paths, races, off-by-one) → security (injection, path traversal, secrets, unsafe exec) → spec compliance (ACs claimed but not implemented, tests that assert nothing, mock the subject or only restate the implementation) → portability (bash-only commands, \ paths, BOMs, >> in PowerShell). --full: run the three lenses correctness, security and spec compliance separately (in parallel if your tool has subagents) and merge, dropping duplicates.
  4. Report in the shape below. Optional machine form, reports/review.json: {"ok":false,"findings":[{"severity":"high","file":"src/a.ts","line":88,"summary":"..."}]}.
  5. Hand back. Each critical or high finding becomes a task in spec.md (### T-09 Fix empty evidence + - AC: AC-02 | Files: ... | Test: ...) for sw-do, or is fixed and re-tested now. Then verify again and close with sw-done.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

review is a skill published in the GitHub repository anton-abyzov/specweave (167 stars, last pushed today), licensed MIT. It adds 45 tokens to every session and 1,180 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
