Skillselion indexes the agent ecosystem and runs ongoing research on it: dated censuses of security, copying, usage and maintenance, with the raw dataset behind every number. Free to cite - browse Skillselion Research. How the numbers are made: methodology.
Hands-on guides to the most-installed agent skills - what each one does and when to use it - browse all guides.
The core toolkit for anything agentic - agent building, LLM integration, RAG and generative media. Skills and MCP servers that give your coding agent new capabilities.
The visual layer - UI and UX design, CSS and Tailwind, design systems, animation, accessibility and design-to-code. For shipping a real frontend with Claude Code, Codex or Cursor.
The server side - APIs, databases, full-stack scaffolding, data analytics and ML. Tools for wiring up the backend and data layer of a real product.
The everyday inner loop - CLI and terminal, Git and pull requests, debugging and per-language helpers (Python, Go, Rust and more) that make coding faster.
Take the repetitive work off your plate - CI/CD, release automation, browser and web automation, and DevOps workflows your agent can drive end to end.
Keep quality high before you ship - automated testing, QA and code review skills that catch bugs and enforce standards your agent can run on every change.
Ship safer - security and pentesting tools that find vulnerabilities, harden your stack and review code for risks before they reach production.
Run what you shipped - observability, monitoring and cloud infrastructure tools, from logs and metrics to managing the cloud your product runs on.
Stay organized while you build - documentation, planning, research, productivity and communication skills that scope the work and write it up.
An automatically updated directory of skills, MCP servers and marketplaces for Claude Code, Codex, Cursor and other coding agents - ranked by real installs. It doubles as a research organization: Skillselion Research publishes dated censuses and open datasets measuring the ecosystem itself.
Yes - that is what separates it from a plain directory. Skillselion Research runs ongoing censuses of the agent ecosystem (security audit coverage, verified copies, install-weighted use cases, code maintenance) plus an always-current statistics reference. Every edition is frozen on publication, free to cite with attribution, and ships its raw dataset as CSV. How the numbers are made is at /research/methodology.
Automatically updated and ranked by real adoption - we track installs and GitHub stars across Anthropic, OpenAI and Cursor tools so you find and compare what is actually used.
No. Browsing, search and the brief are free.
No. Independent project, not affiliated with or endorsed by any tool maker.
No - everything here is free to browse without one.
Not ourselves. Listings surface third-party audit verdicts (Socket, Snyk and other skills.sh auditors) where they exist - outside signals we pass through, not a scan we run and not a safety guarantee. Our Agent Skill Security Census measures that coverage across the whole ecosystem: 87.8% of listings have never been audited by anyone. Review a tool before you install it.
Send us a note through the Feedback page. We read every message - whether it’s a stale entry to fix or a tool we should add. The directory is updated automatically and ranked by real installs.
