# Skillselion > Skillselion (https://skillselion.com) is an independent, automatically updated directory of skills, MCP servers, marketplaces and workflows for Claude Code, Codex, Cursor and other coding agents, ranked by real installs. We track installs and GitHub stars across Anthropic, OpenAI and Cursor tools so you find and compare what is actually used. Built for developers shipping real products. Skillselion is not affiliated with Anthropic, OpenAI, Cursor, Claude, Claude Code, or Codex. Last updated: 2026-08-05 ## At a glance - 80,260 tools indexed in total: 59,184 agent skills, 8,427 MCP servers, 12,649 plugin marketplaces. - Ranked by real installs (155,947,435 tracked across the catalog), then GitHub stars - not alphabetical, not vote-based. - Covers Claude Code, Codex and Cursor - not a single-agent directory. - Automatically updated daily from GitHub and the skills.sh registry; dead repos are pruned. - Independent and free; no signup required to browse or install. ## Definitions - **Agent skill**: a single SKILL.md instruction set (often with bundled scripts) that teaches a coding agent like Claude Code, Codex or Cursor how to do one task well. Installs with one command. - **MCP server**: a Model Context Protocol server that extends a coding agent with external tools, APIs and integrations. - **Marketplace**: a GitHub repo that hosts and distributes multiple plugins under one registry; added with `/plugin marketplace add `. - **Workflow**: a multi-step, multi-tool routine for a recurring job, as opposed to a single-task skill. ## Most-installed agent skills right now - find-skills (vercel-labs) - 2,820,575 installs, 28,045 GitHub stars: Find Skills is a Vercel Labs agent skill that helps developers discover and install capabilities from the open agent skills ecosystem instead of reinventing workflows from scratch. https://skillselion.com/skills/vercel-labs/skills/find-skills - grill-me (mattpocock) - 754,978 installs, 203,487 GitHub stars: grill-me is a user-invoked entry point that runs the repo's grilling session: the agent interviews the developer relentlessly about every aspect of a plan or design until both reach a shared understanding. https://skillselion.com/skills/mattpocock/skills/grill-me - frontend-design (anthropics) - 741,882 installs, 166,273 GitHub stars: Frontend Design is Anthropic's agent skill for creating memorable, production-grade web interfaces that deliberately avoid generic AI aesthetics. https://skillselion.com/skills/anthropics/skills/frontend-design - grill-with-docs (mattpocock) - 640,838 installs, 203,487 GitHub stars: grill-with-docs runs a relentless interview (a /grilling session) to sharpen a plan or design, and leaves a paper trail as it goes: it drives the /domain-modeling skill so resolved terminology lands in CONTEXT.md and hard-to-reverse decisions become ADRs. https://skillselion.com/skills/mattpocock/skills/grill-with-docs - agent-browser (vercel-labs) - 628,408 installs, 39,925 GitHub stars: agent-browser is a Vercel Labs browser automation CLI packaged as an agent skill that gives a coding agent control over websites and Electron desktop apps. https://skillselion.com/skills/vercel-labs/agent-browser Full live leaderboard: https://skillselion.com/skills ## What you can find here - Thousands of tools for Claude Code, Codex, and Cursor, ranked by real installs and automatically updated, each with install commands, trust signals (GitHub stars, installs), and an at-a-glance summary. - Tools are organized primarily by **type** (skill, MCP server, marketplace, plugin, workflow) and **category**, with an optional **build-stage** lens for browsing by where you are in a project. ## Tool types - Agent skills: https://skillselion.com/skills - MCP servers: https://skillselion.com/mcp - Marketplaces: https://skillselion.com/marketplaces - Browse / search everything: https://skillselion.com/browse ## Browse by build stage - Idea - shaping what to build: https://skillselion.com/phase/idea - Validate - testing the idea: https://skillselion.com/phase/validate - Build - writing the product: https://skillselion.com/phase/build - Ship - releasing it: https://skillselion.com/phase/ship - Launch - getting first users: https://skillselion.com/phase/launch - Grow - acquiring and retaining: https://skillselion.com/phase/grow - Operate - running it in production: https://skillselion.com/phase/operate ## Comparison shortlists (best X for Y) Ranked, answer-first shortlists - the fastest way to cite a recommendation.
