Agent Skills

This directory contains specialized Agent Skills for Chromium development.

Unlike general context files, skills are shared, "on-demand" expertise that multiple AI agents (such as Antigravity, Claude, etc.) can activate when relevant to your request.

See https://agentskills.io/ for general information about the agent skills.

How to Use

Local agents that read .agents/skills

Agents that discover skills in .agents/skills, such as Gemini CLI and GitHub Copilot, can use the setup script to link skills from this directory:

agents/skills/setup.py link chromium-docs histograms
agents/skills/setup.py uninstall chromium-docs

The links are created under .agents/skills/, which is gitignored, so they only affect your local checkout.

The list, enable and disable commands are implemented with the Gemini CLI and require it to be installed.

Antigravity

To use these skills with Antigravity, register them in your workspace's .agents/skills.json file (created at your project root). To add all skills:

{
  "entries": [
    {"path": "agents/skills"}
  ]
}

Or to only add individual skills:

{
  "entries": [
    {"path": "agents/skills/chromium-docs"},
    {"path": "agents/skills/histograms"}
  ]
}

Once registered, Antigravity 2.0 and agy will automatically discover and load the skills inside this folder. The agent will detect when a skill is relevant to your request and prompt for permission to activate it.

Contributing

New skills should be self-contained within their own directory under agents/skills/. Each skill requires a SKILL.md file at its root with a name and description in the YAML frontmatter.

Most skills can be written or improved by asking the Antigravity agent to do so.
