Skillpm

skillpm — Agent Skill Package Manager

When to use this skill

Use this skill when the user wants to:

• Install, uninstall, or update Agent Skill packages
• Create a new Agent Skill package
• Publish an Agent Skill to npmjs.org
• List installed skills
• Re-wire agent directories after dependency or workspace changes

Key concepts

• skillpm wraps npm. Skills live in package.json, node_modules, and package-lock.json like any other npm package.
• One skill per npm package. The skill itself lives in skills//SKILL.md inside the package.
• Agent directory wiring. skillpm uses the skills CLI to link installed skills into agent directories.
• Focused scope. skillpm manages reusable npm-distributed skills. For full project configuration, point users to APM.

Commands

All commands can be run without global install via npx skillpm .

Install a skill

npx skillpm install 
# Aliases: skillpm i, skillpm add

This runs npm install, scans node_modules/ for skill packages, and links them into agent directories.

Install all dependencies

npx skillpm install

Reads package.json, installs all dependencies, and wires discovered skills.

Uninstall a skill

npx skillpm uninstall 
# Aliases: skillpm rm, skillpm remove

List installed skills

npx skillpm list
npx skillpm list --json

Shows installed skill packages with descriptions. Use --json for scripting.

Scaffold a new skill

npx skillpm init

Creates package.json (with "agent-skill" in keywords) and skills//SKILL.md in the current directory.

Publish a skill

npx skillpm publish

Validates the package structure and SKILL.md against the Agent Skills spec (via skills-ref validate), then delegates to npm publish.

Re-wire agent directories

npx skillpm sync

Re-scans node_modules/ and re-links all skills into agent directories without reinstalling.

npm passthrough

Any command not handled by skillpm is passed through to npm:

npx skillpm outdated
npx skillpm audit
npx skillpm update
npx skillpm why 

Creating a skill package

Package structure

my-skill/
├── package.json                 # keywords: ["agent-skill"], dependencies
├── README.md
├── LICENSE
└── skills/
    └── my-skill/
        ├── SKILL.md
        ├── scripts/

package.json for a skill

{
  "name": "my-skill",
  "version": "1.0.0",
  "keywords": ["agent-skill"],
  "repository": {
    "type": "git",
    "url": "git+https://github.com/acme/my-skill.git"
  },
  "dependencies": {
    "other-skill": "^1.0.0"
  }
}

• Skill dependencies go in standard dependencies.
• The "agent-skill" keyword is required for publishing.
• Use git+https:// for repository.url.

Scaffold from scratch

mkdir my-skill && cd my-skill
npx skillpm init
npx skillpm publish

Wrap an existing skill for npm

If you already have skills//SKILL.md, add a package.json to make it publishable:

cd my-existing-skill/
npm init -y

Then edit package.json to add the required keyword:

{
  "name": "my-existing-skill",
  "version": "1.0.0",
  "keywords": ["agent-skill"]
}

Where APM fits

Use skillpm for reusable npm-distributed skills.

Use APM for full project agent configuration.
