Code Review — Yosemite Crew

Description

Use this skill when reviewing code, checking a PR, or performing an adversarial review of changes. Runs through quality, security, accessibility, and convention checks specific to this codebase.

TRIGGER: when asked to review code, check a PR, or audit changes in any part of this monorepo.

Review Checklist

Universal (all apps)

• No secrets, tokens, or .env values in code
• TypeScript: no any, no unnecessary type assertions
• Conventional commit message format (scope must match root policy in AGENTS.md and commitlint.config.cjs)
• No console.log in production code (use Winston for backend, remove for frontend/mobile)
• No new eslint-disable comments — fix the root cause
• No new files when editing an existing file would suffice
• No duplicate imports in any file

Frontend Specific

• New UI uses existing src/app/ui/ components before creating new ones
• Tailwind tokens used — no hardcoded colors or arbitrary values without justification
• No new Bootstrap classes added
• Sonar rules not violated (see frontend-sonar skill)
• Semantic HTML — no <div role="..."> where a native element exists
• Keyboard accessibility — interactive elements have tabIndex and onKeyDown
• No <button> nested inside <button>
• Zustand store used correctly — no duplicated state across stores
• Cognitive complexity ≤ 15 per function/component
• No nested ternaries inline in JSX
• useState destructured correctly; no empty first slot

Backend Specific

• Business logic in service layer, not controller
• All req.body inputs validated with Zod
• No raw database queries outside model/service layer
• Background work enqueued via BullMQ, not processed inline
• Stripe webhook handlers verify signature

Mobile Specific

• User-visible strings use t() from i18next
• Navigation uses typed route names
• Redux for shared/persisted state; useState for ephemeral UI state
• Native permissions requested before use

How to Run a Review

1. Read the changed files.
2. Run through the relevant checklist sections above.
3. For frontend changes, run: npx tsc --noemit + pnpm --filter frontend run lint.
4. For frontend changes, run targeted tests for every modified file: pnpm --filter frontend run test -- --testPathPatterns="<ModifiedFile>". Verify no existing tests are broken by the change.
5. For each issue found, state: file + line, the rule violated, and the fix.
6. Summarize: blocking issues vs. suggestions.
