reviewing-code

reviewing-code is a skill for Claude Code, Codex from bostonaholic/team. It costs 23 tokens per session (816 once invoked), scanned A, original, MIT.

A code-review guide for having a separate reviewer inspect a code change for defects, judge their severity, and write a structured report.

In plain words
What is it for?
It helps review diffs, classify findings by severity, and record reviewer verdicts.
Why use it?
It reduces self-review bias by keeping the person who wrote the code from approving it. It also gives reviewers shared rules for deciding what should block a change.

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

reviewing-code 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 4d 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 — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Reviewing Code

Review with fresh context. The generator never evaluates or fixes its output. Reviewers have read-only tools and permissionMode: plan (principle-generator-evaluator, principle-least-privilege). Read references/review-manual.md. Call the Skill tool with writing-prose and apply Self-lint before returning the report.

Report Format

Emit every heading below in order. Use Code Reviewer tokens from Verdict Criteria first. Relay the full report unchanged (principle-skip-loudly).

**Verdict: <✅ APPROVE | ❌ REQUEST CHANGES | 💬 COMMENT>**

### Summary
<Two to five sentences: scope and verdict reason.>
### Findings
<Conventional Comments with `file:line`, or exactly "No findings.">
### Checks
<Every done criterion and each command/result.>
### Refuted by verification
<Refuted findings, exactly "Nothing refuted.", or "Not run: <reason>.">
### Cross-model disposition
<Per `skills/cross-model-review/SKILL.md`, or "Not run: <reason>.">

Gate Types and Severity Tiers

Call the Skill tool with review-severity-tiers; it owns gates, tiers, auto-fix, consult, and aggregation. Findings use skills/conventional-comments/SKILL.md; UX uses Working/Broken/Could Improve.

Verdict Criteria

Security Reviewer

PASS unless CRITICAL or HIGH exists; either causes FAIL. MEDIUM/LOW findings are reported but do not block.

Verifier

PASS only when format, lint, typecheck, build, and test pass. Any failure returns to IMPLEMENT.

Code Reviewer

✅ APPROVE: done criteria met, no blockers, tests pass. ❌ REQUEST CHANGES: a Blocking issue; return to IMPLEMENT. 💬 COMMENT: only non-blocking suggestions.

Test-quality flags. Call the Skill tool with test-style. One change-detector, mock-chain, overbroad equality, test logic, method-named test, or opaque helper is suggestion:; repetition across tests is issue:.

Flaky-test red flags (always blocking). When a test outcome depends on a nondeterministic input, the first occurrence is issue (blocking). The catalog lives only in skills/test-style/SKILL.md.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

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.
