Ts review

Skill widnyana/eyay-toolkits/plugins/ts-backend-dev/skills/ts-review

Review TypeScript code for quality, security, and correctness. Use this skill when the user asks for a code review, wants feedback on a PR or diff, or says "review this". Covers architecture, security, error handling, database patterns, type safety, and code quality. Produces categorized findings: critical issues, improvements, suggestions, and positive notes. Also triggers on phrases like "check this code", "what do you think of this", or "any issues with".From its SKILL.md

Code Review

Review: $ARGUMENTS

Review Checklist

1. Architecture & Patterns

  • Clear separation of concerns (routing, business logic, data access)
  • Dependency injection or explicit dependencies (no hidden globals)
  • Service/module layer handles business logic, not handlers/controllers
  • Input validation at the boundary (DTOs, schemas, zod, class-validator)

2. Security

  • Auth checks on sensitive endpoints
  • Role-based or scope-based access control where needed
  • No hardcoded secrets, credentials, or API keys
  • Input validation and sanitization on all public inputs
  • Parameterized queries (no string interpolation in SQL)
  • Webhook signature verification
  • No sensitive data in logs or error responses

3. Error Handling

  • Errors are properly typed and propagated
  • Error messages don't leak internals to clients
  • External service calls wrapped in try-catch
  • Graceful degradation where appropriate
  • No swallowed errors (empty catch blocks)

4. Database

  • Transactions for multi-step operations
  • Proper indexing for query patterns
  • No N+1 queries
  • Connection handling (pools, timeouts, cleanup)

5. TypeScript-Specific

  • No any without justification
  • Proper type annotations on public APIs
  • Discriminated unions over optional sprawl
  • Null/undefined handled explicitly (no implicit ! abuse)
  • Generics used where they add value, not everywhere

6. Code Quality

  • Single responsibility per function/class
  • No duplicated logic that should be shared
  • Descriptive names (no data, info, result as sole identifiers)
  • No dead code or unreachable branches
  • Consistent style with the rest of the codebase

Output Format

Provide:

  1. Summary: Overall assessment in 1-2 sentences
  2. Critical Issues: Must fix before merge
  3. Improvements: Should fix
  4. Suggestions: Nice to have
  5. Positive Notes: What's done well
