500 curated skills and counting. A library of production-grade Agent Skills (SKILL.md procedures) that give coding agents — OpenCode, Claude Code, Cursor, Codex, Copilot, Gemini CLI and 75+ more — the procedural knowledge of an entire senior team across dozens of professions.
Every skill contains: concrete numbered steps, common pitfalls, success signals/KPIs, and copy-paste commands. Authored from real workflows — no filler, no near-duplicate stamping, no AI slop.

Browse, search (Ctrl+K), filter, and copy install commands at the companion web app — Next.js, fully static, animated, RSS feed included:
npm install && npm run dev # local development
npm run gen # regenerate SKILL.md files from src/data/
node scripts/verify-routes.mjs # verify every route exists in build outputsrc/data/tracks/*.mjs ← structured knowledge base (source of truth)
│
▼ node scripts/generate.mjs
skills/<slug>/SKILL.md ← Agent Skills format, auto-generated + indexed
│
▼ npx skills add aniruddhaadak80/skills
Your agent ← discovers + activates skills on demand
Each skill follows the open spec:
---
name: my-skill
description: What it does + when the agent should activate it
---
# Steps, pitfalls, success signals, commands…The generator also emits public/search-index.json (powers the site's Ctrl+K palette) and validates slug uniqueness across the whole library.
The architecture is built to reach six figures of skills without quality collapse:
- Expansion packs — new domains per track; each procedure = an installable skill
- Stack/tool variants — universal procedures multiply with genuinely stack-specific steps
- Playbook compositions — new journeys assemble existing skills into guided sequences
- Community contributions — PRs adding procedures auto-generate installable skills + site pages
Honest note from the author: this repo ships only skills that pass a quality bar — real steps, real pitfalls, no template spam. Volume follows quality, never the reverse.
Read CONTRIBUTING.md — it covers the quality bar, full schema reference, and local workflow. Short version:
- Pick a track you have real production experience in
- Add a procedure object to
src/data/tracks/<track>.mjsfollowing the schema - Run
npm run gen+node scripts/validate-data.mjs— your SKILL.md, website page, and index entry appear automatically - Open a PR; automated review checks everything (data QA, generated-file sync, route integrity) and labels it instantly
Every merged PR earns you a place on the auto-updated contributors wall below.
Thank you to everyone who has helped build the Agent Skills Directory!
