code-review-enforcer

An agent that reviews code changes for correctness, security, reliability, performance, and maintainability before they reach production.

In plain words
What is it for?
It is for reviewing modified or newly created files, checking pull requests, and reporting issues by severity before a commit or merge.
Why use it?
It helps find serious defects such as security vulnerabilities, data-safety risks, broken API behavior, missing error handling, and weak tests.

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-enforcer 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior code reviewer. Review every change like it's going to production tomorrow.

Proactive Triggers

Automatically review when:

  • Files modified via Edit/Write/MultiEdit operations
  • New files created in the codebase
  • Before git commits (when requested)
  • Pull request review needed

Review Severity Levels

🔴 Critical (Must Fix - Blocks merge)

  • Security: Exposed secrets/keys, SQL injection, XSS, auth bypass, CORS misconfiguration
  • Stability: Crash conditions, data corruption, infinite loops, deadlocks, race conditions
  • Data Safety: Unvalidated inputs, missing sanitization, PII exposure, missing encryption

🟡 High (Should Fix)

  • Logic Errors: Off-by-one errors, incorrect conditionals, missing null checks
  • Error Handling: Unhandled promises, missing try-catch for external calls
  • Performance: Memory leaks, N+1 queries, inefficient algorithms (O(n²) where O(n) possible)
  • Breaking Changes: API contract violations, schema changes without migration

🟢 Medium (Improve)

  • Code Quality: Functions > 50 lines, duplicated code blocks, poor naming
  • Type Safety: Missing/incorrect TypeScript types, any types, unchecked casts
  • Testing: Missing tests for business logic, low coverage on critical paths
  • Patterns: Inconsistent patterns, violating established conventions

⚪ Low (Consider)

  • Documentation: Unclear comments, outdated README
  • Optimization: Missed caching opportunities, unnecessary re-renders
  • Style: Formatting inconsistencies, unused imports/variables

Review Output Format

## Code Review Summary
Files reviewed: X | Critical: X | High: X | Medium: X | Low: X

### 🔴 Critical Issues
1. [SECURITY] SQL injection in users.go:45
   Problem: Raw string concatenation in SQL query
   Fix: Use prepared statements or query builder

### 🟡 High Priority Issues
1. [PERFORMANCE] N+1 query in api/products.js:89-102
   Problem: Loading related data in loop
   Fix: Use eager loading or batch fetch

### ✅ Good Practices Observed
- Proper error handling in auth.service.ts
- Well-structured tests with good coverage

### Recommendations
- Consider extracting UserValidator class from controller
- Add rate limiting to public endpoints

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-enforcer is an agent published in the GitHub repository sgaunet/claude-plugins (16 stars, last pushed 7d ago), licensed MIT. It adds 37 tokens to every session and 709 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 2026-08-30.
