Skills registry - Sei Docs

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 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:

npx skills add https://docs.sei.io

The CLI lists every skill this site serves and installs the ones you pick. To install one skill without the prompt, pass its name with --skill:

npx skills add https://docs.sei.io --skill sei-nodes

Foundation skills

Filter by area to find what fits your project. Each card copies the command that installs only that skill, which keeps your assistant’s context small.

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 short playbook of Sei-specific facts, code, and pitfalls.

Discoverable by agents

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.

Generated from sei-skill

Skill content comes from 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.

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 from its repository instead.

Use a Foundation skill when	Use the full 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.
