Claude Skills

The open format is called Agent Skills and works in Claude Code, Codex, Cursor and other agents — most people know it as Claude Skills.

Every Agent Skill we could find on GitHub, deduplicated by content. 79 600 files from 1 763 authors, of which 61 947 are unique — the rest is the same skill repackaged into someone else's repository. For each one: what it weighs in tokens, whether it ships runnable scripts, and which MCP servers it needs.

Site Diagnosis
by glebis

Pre-consultation diagnostic questionnaire for clients building websites with AI tools (Claude, Codex, Cursor, Bolt, v0, etc.) who have concerns about quality, design, or maintainability.

Skill Studio
by glebis

Interview-driven automation design tool. This skill should be used when the user wants to design a new skill, agent, automation, shortcut, or any other automatable workflow. Runs a coverage-driven JTBD interview (text or voice), then exports a one-page markdown spec plus an SVG design map. Can also analyze Claude Code sessions (current or by ID) to extract workflows, subagent patterns, and skill usage, then propose new skills based on observed patterns. Use this skill whenever the user mentions analyzing a session, extracting workflows, proposing skills from past work, reviewing what tools or agents were used, or turning a session into a skill. Triggers on "analyze this session", "what skills could I build from this", "propose skills from session", "what workflows did I use", "what did I do in this session", "extract patterns", "turn this into a skill".

Disk Cleanup
by glebis

Scan and clean macOS caches, package-manager data, crash dumps, and app caches to reclaim disk space. Deterministic — a config registry (targets.json) plus two scripts (survey.py read-only, clean.py executor) do all the measuring and deleting; the agent only relays a compressed summary and makes the few human-judgment calls. IMPORTANT — use this skill whenever the user's request on macOS involves: freeing disk space, cleaning/clearing caches, "disk is full", "clean up my Mac", "free up space", "what's eating my disk", "running low on disk", needing space for an install, or any low-storage complaint. Covers the whole workflow survey → choose → clean → empty Trash.

Cmux
by glebis

Controls the cmux macOS terminal app (Ghostty-based, AI-agent-aware) via its CLI socket API. Use this skill to: open browser preview panes when a dev server starts or an HTML file is created; spin up named workspaces for parallel subagents; show live sidebar progress/status during long tasks; open utility splits on demand (logs, URLs, terminals) in any direction. Also handles `/cmux demo` — an interactive walkthrough with 3 screens of options that runs personalized live demos. Trigger when: a server starts and needs previewing, an HTML/URL artifact is created, parallel subagents are dispatched, a long task needs visible progress, the user asks to open/show something in a split or tab, or the user invokes `/cmux demo`.

Triggers on "babysit this job", "watch this until it's done", "ping me when the encode/embed/batch finishes", "is this background process stuck", "monitor this ffmpeg/qmd run", or any request to wait on a long-running process and be told when it's complete or hung.

The Goal
by glebis

A Theory-of-Constraints diagnostic for deciding what to automate with AI agents. Before building any automation, skill, Goal, loop, or schedule, it walks Goldratt's Five Focusing Steps over the user's work system to find the real bottleneck, then recommends the single highest-leverage automation aimed at the constraint plus a what-NOT-to-automate list. Use when the user asks "what should I automate", "where do I point my agents", "prioritize my automation backlog", "which workflow should I agentify", "is this worth building", "find my bottleneck", "what's the highest-leverage thing", when they are about to build a Claude Code skill/Goal/loop/schedule and aren't sure it matters, or during a review of their automations. Guards against the common failure of automating busywork (a local optimum) instead of the constraint.

Claude Skills — questions

Answers built from the skills we actually parsed.

What is a Claude Skill?
A folder with a SKILL.md file: instructions that teach an agent to do one thing well, optionally with scripts and reference files alongside. The format is open and called Agent Skills — Claude Code, Codex and other agents read the same files. It is not a program you run; it is knowledge the agent loads when the task calls for it.
How is a skill different from an MCP server?
A server gives the agent new abilities — it connects to something and exposes tools. A skill gives the agent knowledge: how to use what it already has. They combine, and often literally: 11 352 of the skills here declare which MCP servers they need to work.
Why are there fewer skills here than in other catalogues?
Because we deduplicate by content. Of 79 600 files found on GitHub, 61 947 are unique — the rest is the same skill copied into someone else's repository, word for word. Catalogues that count files rather than skills show every copy as a separate entry.
What does the token count mean?
A skill is loaded into the model's context when it is used, so its size is a running cost on every request that touches it. We measure the whole folder, not just SKILL.md: one official skill is 377 tokens, another drags 83 files of fonts behind it.
How do I install a skill?
Copy the skill folder into ~/.claude/skills for personal use, or into .claude/skills inside a project. The agent picks it up by the name in the SKILL.md header — which is worth checking: 7 890 skills here share a name with another skill, and two of them cannot sit side by side.
