review-code

A checklist for reviewing code for correctness, readability, security, maintainability, TypeScript usage, React practices, and applicable Next.js conventions.

In plain words
What is it for?
Reviewing React and TypeScript changes, checking loading and error states, finding duplication or oversized functions, and verifying Next.js and accessibility-related practices.
Why use it?
It gives reviewers a consistent way to spot bugs, missing edge cases, unclear code, unsafe patterns, and project-standard violations.

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.

Made for: Cursor.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 642 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

review-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 yesterday.

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.

Review Code

Overview

Comprehensive code review checklist to ensure quality, security, and maintainability.

Review Categories

1. Functionality

  • Code does what it's supposed to do
  • Edge cases are handled
  • Error handling is appropriate
  • No obvious bugs or logic errors
  • Loading and error states work correctly

2. Code Quality

  • Code is readable and well-structured
  • Functions are small and focused (<50 lines)
  • Components are reasonable size (<200 lines)
  • Variable names are descriptive
  • No code duplication
  • Follows project conventions
  • Complex logic has comments

3. TypeScript

  • All props have interfaces
  • No 'any' types (use 'unknown' if needed)
  • Return types defined for functions
  • Proper type inference used
  • Exported types when shared

4. React Best Practices

  • Functional components used
  • Proper hook usage (no violations of rules)
  • Keys provided for list items
  • No inline functions in JSX (use useCallback)
  • Memoization used appropriately
  • Server Components used when possible (Next.js)

5. Next.js Specific (if applicable)

  • Server Components used by default
  • 'use client' only when necessary
  • Metadata properly defined
  • Images use next/image
  • Loading and error UI provided
  • Proper caching strategy

6. Styling

  • Tailwind CSS used consistently
  • Responsive design implemented
  • Dark mode support (if required)
  • No inline styles (use Tailwind)

7. Security

  • No obvious security vulnerabilities
  • Input validation present
  • Sensitive data handled properly
  • No hardcoded secrets
  • XSS prevention in place

8. Accessibility

  • Semantic HTML used
  • ARIA labels where needed
  • Keyboard navigation works
  • Proper color contrast
  • Focus states visible

9. Performance

  • No unnecessary re-renders
  • Large lists virtualized (if needed)
  • Images optimized
  • Code splitting implemented
  • Bundle size considered

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.

review-code is a command published in the GitHub repository Farzannajipour/cursor-react-rules (3 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 642 tokens. 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.
