Code Review — StarMapper

Pre-PR local review analyzing recent changes against StarMapper conventions.

Usage

/tech:codereview              # Standard review of staged/recent changes
/tech:codereview --auto       # Review + auto-fix loop (max 3 iterations)
/tech:codereview --multi-agent # 4 parallel agents (comprehensive)
/tech:codereview --focus security   # Single dimension
/tech:codereview --focus performance
/tech:codereview --focus types

Step 1: Get context

rtk git diff --staged
rtk git diff HEAD~1
rtk git status

Identify: which files changed, what kind of change (API route, component, lib, schema).

Step 2: Conditionally load guides

• .ts/.tsx files → apply code-conventions.md rules
• src/components/** → apply design-system.md + react-ref-patterns.md
• src/lib/geocoder* → apply defensive-code-audit.md + rate limit rules
• src/app/api/** → apply API route conventions from architecture.md
• prisma/schema.prisma → apply Prisma + Neon adapter pattern rules
• src/components/map/** → apply MapLibre GL 5.x patterns

Step 3: Analyze (3 severity levels)

🔴 Blocking (must fix before merge)

• Hardcoded tokens, secrets, or API keys
• GitHub token exposed in client bundle
• XSS vector in MapLibre popup innerHTML
• function keyword instead of arrow function
• any type without justification
• Nominatim called in parallel (rate ban risk)
• Server-side loop over all stargazers (Vercel 10s limit)
• Raw JSON payload for large repos (4.5MB limit)
• Missing ssr: false on MapLibre dynamic import
• Prisma write without try/catch

🟡 Important (should fix, non-blocking)

• Missing import type for type-only imports
• Arbitrary Tailwind values (w-[Npx], bg-[#xxx])
• console.log left in code
• Missing DB health guard on new cache writes
• forEach with async callback
• Geocache key not normalized (toLowerCase().trim())
• Silent catch (error swallowed, no response returned)
• cursor: null passed as GraphQL variable

🟢 Suggestions (optional improvements)

• memo() opportunity on component that re-renders frequently
• useMemo() for GeoJSON feature array construction
• Promise.all() for independent async operations
• Unused imports

Step 4: Report

## Code Review — StarMapper

**Files reviewed**: [list]
**Change type**: [API route / component / lib / schema]

### 🔴 Blocking Issues (N)
1. **[Category]**: [Description]
   File: `src/...` line N
   Fix: [concrete fix]

### 🟡 Important Issues (N)
1. **[Category]**: [Description]
   File: `src/...` line N
   Suggestion: [concrete improvement]

### 🟢 Suggestions (N)
1. ...

### ✅ Patterns Verified
- [ ] Arrow functions only
- [ ] Type imports separate
- [ ] No any
- [ ] CSS tokens used (no arbitrary values)
- [ ] MapLibre ssr:false
- [ ] Geocache key normalized
- [ ] Rate limit guards present
- [ ] No console.log

Mode: --auto

Iterative fix loop (max 3 iterations):

1. Run review → identify blocking + important issues
2. Apply fixes one by one
3. Re-run rtk tsc + pnpm lint after each batch
4. Stop when: zero blocking + zero important issues OR 3 iterations reached
5. Output summary: what was fixed, what remains

Safety: Never edit .env* files. Confirm before modifying > 5 files.

Mode: --multi-agent

Launch 4 parallel specialized agents and reconcile results:

Agent 1 — Architecture & Chunk Pattern Auditor

• Verifies chunk loop integrity (no server-side loops)
• Checks Vercel constraint compliance (10s, 4.5MB)
• Reviews cache strategy (geocache, stargazer cache, badge cache)

Agent 2 — StarMapper Patterns Enforcer

• TypeScript conventions (arrow functions, type imports, no any)
• Tailwind v4 design system compliance (tokens, no arbitrary values)
• MapLibre GL 5.x patterns (Promise-based API, ssr:false, cleanup)
• Geocoder patterns (normalized key, cache-first, sequential)

Agent 3 — Performance & Rate Limit Auditor

• GitHub GraphQL rate limit handling
• Nominatim: sequential calls, 1100ms delay
• Circuit breaker presence for Jawg/Geoapify
• MapLibre render performance (memo, useMemo)
• Bundle size implications

Agent 4 — Defensive Code Auditor

• No silent catches in API routes
• No || {} on Prisma returns
• No forEach with async
• DB health guard on writes
• XSS in MapLibre popups

Reconciliation:

• Deduplicate findings across agents
• Merge into unified report with severity
• Highlight consensus findings (flagged by 2+ agents)
