# Skills registry

> Install Sei Foundation agent skills into your AI coding assistant with one command. Each skill teaches your assistant one area of Sei: contracts, frontend, precompiles, nodes, payments, security, bridges, or migration.

Sei Foundation publishes **agent skills**: focused, installable knowledge packs that make your AI coding assistant Sei-aware. This docs site hosts them in the open [`skill.md`](https://www.mintlify.com/docs/ai/skillmd) format, so any assistant that supports agent skills, such as Claude Code or Cursor, can install them.

## Install

Run the `skills` CLI against this site:

```bash theme={null}
npx skills add https://docs.sei.io
```

The CLI lists every skill this site serves and installs the ones you choose.

## Foundation skills

Filter by area to find what fits your project. Every card copies the same install command, so you can pick only the skills you need and keep your assistant's context small.

<SkillsRegistry />

## How the skills work

Each Foundation skill is a single `SKILL.md` file. Its frontmatter tells an assistant **when** to use it, and the body is a focused playbook of Sei-specific facts, code, and pitfalls.

<CardGroup cols={2}>
  <Card title="Discoverable by agents" icon="rss">
    Agents can list every skill at `docs.sei.io/.well-known/agent-skills/index.json` (or the older `/.well-known/skills/index.json`) and fetch any `SKILL.md` directly, with no install step. Agents connected to the docs MCP server also get them as MCP resources.
  </Card>

  <Card title="Generated from sei-skill" icon="code-branch">
    Skill content comes from [`sei-protocol/sei-skill`](https://github.com/sei-protocol/sei-skill). A sync workflow regenerates the files in this repo and opens a pull request for review, and the site serves them once it merges. To fix or extend a skill, open a pull request in sei-skill.
  </Card>
</CardGroup>

## Focused skills or the full sei-skill

Each Foundation skill covers one area. To load one knowledge base that covers every area at once, install the full [sei-skill](/ai/sei-skill) from its repository instead.

| Use a Foundation skill when | Use the full [sei-skill](/ai/sei-skill) when |
| - | - |
| You work mostly in one area, such as contracts | You want every area in one install |
| You want to keep your assistant's context small | You're starting a Sei project from scratch |
| You're composing your own set of skills | You want the full reference files from the sei-skill repository |

## Publish your own skill

Ecosystem teams can publish skills for their own protocols. Any Mintlify site serves the skills in its `.mintlify/skills/` directory, and developers install them with `npx skills add` and your docs URL. Foundation skill content lives in [`sei-protocol/sei-skill`](https://github.com/sei-protocol/sei-skill).
