AI Agent Skill Search and Management

Manage Agent Skills (SKILL.md files) across multiple AI coding agents — Claude Code, Cursor, GitHub Copilot, Windsurf, and more.

Install

pip install skill

Quick Start

from skill import search, create, install, validate

# Create a skill locally
skill = create('my-skill', description='My custom coding rules')

# Validate it
issues = validate('/path/to/skill-dir')

# Search for skills
results = search('react best practices', local_only=True)

# Install to an agent target
install('_local/my-skill', agent_targets=['claude-code'], scope='project')

Link skills from a project

If a project ships skills (in .claude/skills/, {pkg}/data/skills/, or a dedicated folder), you can symlink them all into your agent's skills directory in one shot:

from skill import link_skills

# Point at a project root — it finds the skills automatically
link_skills('/path/to/my-project')

# Or point at the skills folder directly
link_skills('/path/to/my-project/my_pkg/data/skills')

# Symlink into a specific target instead of ~/.claude/skills
link_skills('/path/to/my-project', target='/other/project/.claude/skills')

Each skill is validated before linking — invalid skills are skipped with a warning. The target directory is also checked to ensure it's a recognized skills directory.

CLI

skill create my-skill --description "My custom coding rules"
skill search "react best practices" --local-only
skill validate ./my-skill/
skill list-skills
skill install _local/my-skill --agent-targets claude-code
skill link-skills /path/to/project
skill link-skills /path/to/project --target ~/.claude/skills --force

Shell completion

Enable tab completion for all skill commands:

skill install-completion

This detects your shell (bash/zsh) and adds the registration line to your shell config (~/.bashrc or ~/.zshrc). Restart your shell or source the config file to activate.

If you prefer to set it up manually:

# Add to your shell config:
eval "$(register-python-argcomplete skill)"

The first time you run any skill command without completion set up, you'll see a one-time hint reminding you to run skill install-completion.

Skills

This package ships agent skills you can install into any agent host with gh skill (don't have it? install gh):

gh skill install thorwhalen/skill skill-package-setup --agent claude-code
gh skill install thorwhalen/skill skill-build
gh skill install thorwhalen/skill skill-enable
gh skill install thorwhalen/skill skill-docs
gh skill install thorwhalen/skill skill-manage
gh skill install thorwhalen/skill skill-sync

These are dev/maintainer skills, so they're not bundled in the wheel — install them with gh skill as above. See skill-package-setup for the layout policy this repo follows (real files in skills/, relative symlinks in .claude/skills/).

Packages can also install their own GitHub-published skills programmatically via skill.install_from_github(repo, names, agent='claude-code'), a thin wrapper over the gh skill CLI.

Plugin System

skill has a registry-based plugin architecture with four extension points:

Register at runtime:

from skill.install import agent_targets, AgentTarget

agent_targets.register('windsurf', AgentTarget(
    name='windsurf',
    project_path='{project}/.windsurf/rules/{name}.md',
    format='skill.md',
))

Or via entry points in your pyproject.toml:

[project.entry-points."skill.agent_targets"]
windsurf = "my_package:windsurf_target"

See Plugin System Documentation for full details on contracts, interfaces, and built-in registrations.
