code-review

A review workflow for finding material defects in code, repository changes, pull requests, or completed implementations. It checks whether problems are real, reachable, consequential, and supported by evidence.

In plain words
What is it for?
Use it to audit a diff, pull request, codebase, or completed implementation for defects, plan compliance, and—when requested—testing or other review dimensions.
Why use it?
It helps focus reviewers on issues that could actually harm users or violate the intended plan. It avoids spending the review on style preferences, guesses, or low-impact nits.

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

code-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 2d 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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Code Review

Hard rules

  • Scope from user/task only. Unclear → ask. Don’t widen.
  • Inspect thoroughly; report selectively. Candidate ≠ finding.
  • “No material findings” is valid.
  • No source edits unless asked. Don’t clobber owner git/worktree state.
  • Main agent assigns final findings/scores/verdicts. Child handoffs = evidence.
  • Delegate by default into bounded read-only lanes when safe. “Small/easy” ≠ skip.
  • Leverage subagents — built-in, extensions/plugins, or skills. Follow use-subagents policy; use the host’s selected launcher (on Pi without native subagent_*, use-pi-subagents).

Admit a finding only if

  • concrete failure
  • realistic reachability
  • practical impact
  • safeguards considered
  • action justified now

Omit nits, hypotheticals, and low-impact noise. Don’t hide them in caveats.

Loads

When Read
Broad or deep dimension review, or explicit test/validation review references/review-dimensions.md first
Vs plan/tracker/design/acceptance references/plan-backed-review.md first
Standalone report assets/review-report-template.md before write

Flow

  1. Fix scope/authority/output — ask if needed.
  2. Load conditional resources.
  3. Inspect targets, callers, tests, config, diffs. Note skips + confidence limits.
  4. Delegate review lanes by default (correctness, security, tests, plan-matrix, …).
  5. Run checks/repros that raise confidence; preserve owner state.
  6. Admit → score → cap findings.
  7. Optional decomplex only if complexity-focused and report writable; else built-in simplicity. Don’t merge contracts.
  8. Write .reviews/<slug>.md (unless chat-only/no-write) or return handoff.
  9. Cleanup any workflow runtime/process state.

Scores and caps

Severity S4 critical · S3 high · S2 medium · S1 low · S0 optional
Confidence C3 confirmed · C2 supported · C1 tentative (not a finding yet)

Files

What ships with it

3 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.

code-review is a skill published in the GitHub repository maxedapps/agent-skills (58 stars, last pushed 18d ago), licensed MIT. It adds 64 tokens to every session and 834 once invoked, about $0.0003 per session on Opus 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 2026-08-30.
