agentskills-io

What This Skill Does

The agentskills-io skill is the foundational tool for building, validating, and maintaining portable AI agent behaviors. It enforces the open standard defined by agentskills.io, ensuring that the skills you create for your agents are compatible across the entire AI ecosystem, including Claude Code, Cursor, GitHub Copilot, and various OpenAI-based integrations. By using this skill, you standardize your agent development workflow, allowing you to define clear triggers through the 'Use when...' syntax in the skill metadata, which drastically improves agent discovery and performance. It automates the structural requirements, such as enforcing a SKILL.md format, proper frontmatter configuration, and directory naming conventions.

Installation

You can install this skill directly through your agent's package manager or by setting up the environment via the official repository. To start locally, ensure you have the uv tool installed, then run the following command to set up the validation framework: uv tool install git+https://github.com/agentskills/agentskills#subdirectory=skills-ref. Once installed, you can use the skills-ref CLI to validate your local directories before deployment. If integrating into a broader project, use the command: clawhub install openclaw/skills/skills/killerapp/agentskills-io to pull the skill directly into your agent runtime.

Use Cases

Use this skill when you need to: (1) create a new, reusable capability for an AI agent; (2) validate an existing skill's structure to ensure it meets the open specification; (3) convert monolithic project documentation into modular, portable skill files; (4) troubleshoot metadata errors that prevent your agent from triggering specific functions; or (5) share agent capabilities across different IDEs and coding platforms without rewriting logic or prompts.

Example Prompts

1. "Validate my new skill located in the ./my-awesome-tool directory to ensure it follows the agentskills.io standard."
2. "Create a new skill scaffolding for a file-search utility including the standard frontmatter and a blank SKILL.md file."
3. "Convert my README documentation into a portable agentskills-io compliant SKILL.md format and fix any frontmatter inconsistencies."

Tips & Limitations

Keep your SKILL.md files under 500 lines and your initial discovery metadata under 100 tokens to ensure the agent processes the skill efficiently. Always verify your directory names match your internal name: field exactly, as this is a common failure point for local validation. Note that this skill is primarily a framework and validation tool; while it facilitates cross-platform portability, individual host tools (like Cursor or Copilot) may have specific runtime restrictions on the actual execution code within your scripts/ folder.
