CLSkills is a hub for Claude Code skills, prompt patterns, and AI agent files. Built for developers who want Claude to give them senior-engineer-level expertise on demand.
What's inside (free):
• 2,300+ community-contributed Claude Code skill files. Drop them into ~/.claude/skills/ and Claude instantly understands your stack — Postgres tuning, React debugging, SwiftUI auditing, API design, and more. Every skill is browseable and downloadable without signup.
• 120 prompt patterns I've tested over 3 months. These are the "secret prefixes" the community has discovered (L99, /ghost, OODA, PERSONA, /skeptic, ULTRATHINK, etc.) — none of them are official Anthropic features but Claude consistently recognizes them and changes its behavior. The first 11 are free at /prompts.
• Open submission flow at /submit. I personally review every contribution.
What's paid (cheat sheet, $5–$10):
• All 120 prompt patterns with before/after examples for every code
• "When NOT to use" warnings for each pattern
• Code combos that stack (the most useful part)
• 10 real-world workflow playbooks ("turn an 11pm rant into a Slack message", "debug a flaky test in 30 minutes", "negotiate a job offer", and more)
• Lifetime updates — new patterns get added automatically and existing buyers get an email
• 7-day no-questions refund
Why I built it: I was using Claude Code every day and kept noticing that the same question gave wildly different answers depending on tiny prefixes in front of it. Spent 3 months testing which ones actually worked, dropped the ones that only worked once, and turned the rest into a curated reference.
Stack: Next.js, Upstash Redis, Razorpay (India) + PayPal (international), Resend, Vercel.

Built solo. Currently funded by the cheat sheet sales — that's what lets me keep the free side free.
