Guides and best practices for working with Neon Serverless Postgres. Covers setup, connection methods, branching, autoscaling, scale-to-zero, read replicas, connection pooling, Neon Auth, and the Neon CLI, MCP server, REST API, TypeScript SDK, and Python SDK. Use when users ask about "Neon setup", "connect to Neon", "Neon project", "DATABASE_URL", "serverless Postgres", "Neon CLI", "neonctl", "Neon MCP", "Neon Auth", "@neondatabase/serverless", "@neondatabase/neon-js", "scale to zero", "Neon autoscaling", "Neon read replica", or "Neon connection pooling".
| 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.
Audit and improve web accessibility following WCAG 2.1 guidelines. Use when asked to "improve accessibility", "a11y audit", "WCAG compliance", "screen reader support", "keyboard navigation", or "make accessible".
Apply modern web development best practices for security, compatibility, and code quality. Use when asked to "apply best practices", "security audit", "modernize code", "code quality review", or "check for vulnerabilities".
Optimize Core Web Vitals (LCP, INP, CLS) for better page experience and search ranking. Use when asked to "improve Core Web Vitals", "fix LCP", "reduce CLS", "optimize INP", "page experience optimization", or "fix layout shifts".
Orchestrate a 4-agent cyber defense pipeline to analyze log files for threats. Use when investigating security logs, detecting anomalies in access patterns, classifying breach severity, or generating incident reports from nginx/auth/syslog files.

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 |
## Duplication Report — StarMapper
**Date**: {date}
**Duplication**: X% ({target: < 3%})
**Clones found**: N
### Top Clones
1. [file:line] ↔ [file:line] — {N} lines
Pattern: {brief description}
Action: {extract to / delete duplicate}
### Action Plan
#### Quick Wins (< 30min)
1. ...
#### Refactoring (1-2h)
2. ...
#### Prevention
- Add `pnpm dupes` to CI check
