// Code duplication analysis for StarMapper using jscpd. Detects repeated patterns across geocoding helpers, GitHub API formatting, compression utils, and cache logic.
| Production-tested setup for Tailwind CSS v4 with shadcn/ui, Vite, and React. Use when: initializing React projects with Tailwind v4, setting up shadcn/ui, implementing dark mode, debugging CSS variable issues, fixing theme switching, migrating from Tailwind v3, or encountering color/theming problems. Covers: @theme inline pattern, CSS variable architecture, dark mode with ThemeProvider, component composition, vite.config setup, common v4 gotchas, and production-tested patterns.
Conventional commit with StarMapper scope auto-detection
7-category codebase health audit for StarMapper with weighted scoring and tier system. Run before major releases or architectural changes.
Pre-PR code review for StarMapper. Analyzes recent changes for quality, security, performance, and StarMapper-specific patterns. Supports auto-fix loop and multi-agent modes.
Add a StarMapper badge (world map of stargazers) to the current repo's README. Detects OWNER/REPO from git remote and inserts the HTML block in the right place.
Recherche et debug dans les logs Vercel (production/preview). Supporte la recherche par pattern, filtre par niveau d'erreur, par route API, par déploiement. Utiliser pour diagnostiquer des erreurs de production, tracer des requêtes ou analyser des crashs.

Use this skill when the user asks to run the migrated source command tech-dupes.
/tech:dupes
pnpm dupes (jscpd) on the src/ directoryIf pnpm dupes is not configured, add to package.json:
"dupes": "jscpd src/ --threshold 3 --min-lines 5 --reporters console,json --output .dupes-report"
And install: pnpm add -D jscpd
| Pattern | Location | Risk |
|---|---|---|
location.toLowerCase().trim() | geocoder, routes | Should exist ONLY in geocoder.ts |
| GitHub error parsing | github.ts, chunk/route.ts | Extract to github.ts |
| Compression/decompression logic | page.tsx, cache routes | Extract to lib/compression.ts |
checkDbHealth() call pattern | user-cache, cache routes | OK if identical — it's a guard |
NextResponse.json({ error: ... }) patterns | all routes | Accept duplication here |
cursor ? { cursor } : {} | github.ts | Should only be in github.ts |
| Metric | Target | Action |
|---|---|---|
| Duplication % | < 3% | Above → refactor |
| Clone count | < 10 | Above → prioritize |
| Max clone size | < 25 lines | Above → extract function |
