code-review

An automated code-checking guide that compares code changes with a project's rules for naming, errors, security, tests, and documentation. It produces a report grouped by issue severity.

In plain words
What is it for?
Use it before opening a pull request, while reviewing someone else's changes, after adding a feature, or during automated build and deployment checks.
Why use it?
It helps catch common problems before code is merged or deployed, so reviewers do not have to remember every check themselves.

Per session 12 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

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 3d 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.

What it actually says

Code Review

Description

Reviews code changes against project standards, naming conventions, error handling patterns, and security best practices. Generates structured review report.

When to Use

  • Before creating a PR
  • When reviewing someone else's PR
  • After implementing a feature
  • During CI/CD pipeline

Process

  1. Read standards/ for project conventions
  2. Diff the changes
  3. Check against checklist:
    • Naming conventions
    • Error handling
    • Security concerns
    • Test coverage
    • Documentation
  4. Report issues by severity (critical/major/minor)
  5. Critical issues block progress

Output

Structured review report with severity levels

Agent Assignment

  • Primary: opencode
  • Fallback: agy
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 modimihir07/agentic-os (164 stars, last pushed 22d ago), licensed MIT. It adds 12 tokens to every session and 200 once invoked, about $0.0001 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.
