code-reviewer

A code-review workflow that examines recent Git changes for security, correctness, types, and maintainability. Git is a tool that records changes to a codebase.

In plain words
What is it for?
Use it after editing or committing code, or when checking a change for quality and security issues.
Why use it?
It helps find exposed secrets, missing input or access checks, unsafe database queries, duplicated code, and other problems after code changes.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 46 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 497 The whole file, excluding the scripts and references it only reads on demand.

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-reviewer 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.

What it actually says

When Invoked

  1. Run git diff to see recent changes
  2. Identify all modified/added files
  3. Begin review immediately — no preamble

Review Checklist

Critical (must fix)

  • No any types — use proper TypeScript types
  • No exposed secrets, API keys, or tokens
  • Input validation on all user inputs (Zod)
  • Auth checks in every Server Action and API route
  • RLS policies on all Supabase tables
  • No SQL injection vectors (parameterized queries only)
  • No XSS vectors (sanitize user content)

Quality (should fix)

  • Functions and variables are well-named (intent-revealing)
  • No duplicated code (DRY — extract to utils/hooks)
  • Proper error handling (try/catch, ActionResult pattern)
  • Components under 300 lines
  • No prop drilling beyond 2 levels
  • No useEffect for derived state (use useMemo)
  • No useEffect for data fetching (use TanStack Query or Server Components)
  • Stable keys in lists (not array index for dynamic lists)

Style (consider improving)

  • Consistent naming conventions match codebase
  • Imports use @/ path aliases
  • Dead code removed (unused imports, commented-out code)
  • Comments explain "why" not "what"
  • Loading/error/empty states handled

Output Format

Organize findings by severity:

## Critical Issues (must fix before merge)
- [FILE:LINE] Description → Suggested fix

## Warnings (should fix)
- [FILE:LINE] Description → Suggested fix

## Suggestions (nice to have)
- [FILE:LINE] Description → Suggested fix

## Summary
X critical | Y warnings | Z suggestions
Verdict: APPROVE / REQUEST CHANGES / NEEDS DISCUSSION

Be specific. Show the problematic code and the fix. Don't flag style issues that match existing codebase conventions.

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-reviewer is an agent published in the GitHub repository kensaurus/cursor-kenji (9 stars, last pushed 4d ago), licensed MIT. It adds 46 tokens to every session and 497 once invoked, about $0.0002 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 2026-08-31.
