Why this catalog

A directory you can cite, not a dump of folders

Closed stores hide the file. Persona packs skip the install path. This AI Agent Skills directory keeps the SKILL.md contract, the folder layout, and the when-to-use line in the open.

SKILL.md first

Every entry is a folder with a name, a description, and a when-to-use line an agent can load.

Named install paths

Claude Code, Cursor, Codex, and Grok Build each have a real skills directory. The guides name them.

English and Chinese

Same catalog, two languages, reciprocal hreflang. You are not stuck with a machine sidebar.

Authoring tools

Generate a draft SKILL.md and validate frontmatter in the browser before you commit the folder.

Find, install, and write Agent Skills

The loop is short on purpose. Discovery without an install path is a bookmark, not a skill.

Find the skill

Search the catalog by task, not by hype. Each card states when the agent should load it.

Install the folder

Copy SKILL.md into the skills directory your agent already reads. The install guide lists Claude, Cursor, Codex, and Grok paths.

Write your own

When a workflow repeats, turn it into a skill. Use the generator and validator, then keep extra files out of the always-loaded markdown.

Make a SKILL.md, then check it

No account. The generator and validator run in your browser and copy a file you can commit.

SKILL.md generator

Fill name, description, and when-to-use. Preview frontmatter. Copy or download a starter folder.

SKILL.md validator

Paste a skill file. Catch missing YAML, bad names, and descriptions that never say when to load.

Agent Skills FAQ

Short answers you can quote. Longer versions live in the guides.

What is an Agent Skill?

An Agent Skill is a folder with a SKILL.md file. The markdown teaches an AI coding agent a repeatable workflow and, in the description, when to load that workflow. It is procedure on disk, not a chat plugin store.

How do I install a skill?

Copy the folder so SKILL.md sits at <name>/SKILL.md inside the skills directory your agent already loads. Claude Code uses .claude/skills, Grok Build uses .grok/skills, Codex uses .agents/skills. See the install guide.

Is a skill the same as MCP?

No. A skill is files that teach a procedure. MCP exposes live tools with schemas. Use a skill when the steps fit in markdown. Use MCP when the agent must call a running API. Many products ship both.

Which agents read SKILL.md?

Claude Code, Cursor, Codex, Grok Build, and several open coding agents load project or user skill folders. The file contract is shared. The directory name is not. Always check the agent docs for the path.

Can I submit a skill to this directory?

Yes. Use the contact form with the slug, license, and a public URL. We summarize in our own words. We do not host binary payloads.
