# Install Agent Skills Install, author, and verify Agent Skills for Antigravity, Codex, OpenCode, Claude, and GitHub Copilot with the `skills` CLI. ## Rules 1. **Default Scope**: Install to the workspace, preferring `.agents/skills/<slug>/`. Use global scope only when explicitly requested. 1. **Review Before Trust**: Before any unattended install, inspect the repository owner, selected ref, every `SKILL.md`, and bundled scripts or executables. Skill text and scripts run with the agent's permissions and are untrusted until reviewed. 1. **CLI First**: Use `skills init` to scaffold an original skill and `skills add <source>` to install a reviewed external skill. Do not reconstruct third-party skills by hand. 1. **Non-Interactive After Review**: Pass `-y` only after source review so automation cannot approve unknown code implicitly. ## Workflow 1. **Identify Source**: Use a Git repository, full URL/subtree, immutable ref when available, or local path containing `SKILL.md` folders. 1. **Choose Scope & Discovery Path**: - **Workspace (recommended)**: `.agents/skills/<slug>/`. Antigravity, Codex, OpenCode, and Copilot discover this path natively. Claude discovers workspace skills from `.claude/skills/`, so link `.claude/skills` to `../.agents/skills`. - **Global**: add `-g` to install under `~/.agents/skills/`. Codex, OpenCode, and Copilot discover that path natively. Claude reaches it through the `~/.claude/skills/` symlink, Antigravity products through `~/.gemini/config
