How to install Agent Skills

SKILL.md is an open standard. The same skill folder works in Claude Code, Cursor, Codex CLI, Gemini CLI, Antigravity, Claude.ai, and the Claude API. Here is the install workflow for each.

Workflow

The 4-step install

  1. 1.

    Pick a Skill

    Find the Skill on this directory. Each Skill page has install commands for every supported agent — copy the one for your agent.

  2. 2.

    Install with the agent CLI

    For Claude Code: npx skills add <repo>. For Cursor: append --target cursor. Codex CLI uses codex skills add. Gemini CLI uses gemini skills add. Antigravity uses antigravity-awesome-skills install.

  3. 3.

    Reload your agent

    In Claude Code, run /reload-plugins. Other agents auto-detect new skills on next launch. The skill metadata is loaded into the system prompt; the body loads on demand when triggered.

  4. 4.

    Verify it loaded

    Ask the agent something the skill is supposed to handle. The skill activates when the request matches its description — you should see it cited or used in the response.
