Install Agent Skills

Install Agent Skills for Antigravity, OpenCode, and Claude with the skills CLI.

Rules

1. Default Scope: Install to the workspace (preferring .agents/skills/<slug>/ when possible) by default. Use global scope only when explicitly requested.
2. CLI First: Use skills add <owner/repo> (or npx skills add ...) to install. Do not hand-write skills unless explicitly asked.
3. Non-Interactive: Always pass -y so autonomous runs never block on a prompt.

Workflow

1. Identify Source: A GitHub repo (<owner/repo>), a full URL/subtree, or a local path containing SKILL.md folders.
2. Choose Scope & Paths:
   • Workspace (default - recommended): .agents/skills/<slug>/. This is the preferred workspace-relative path. Note that while Antigravity and OpenCode can resolve this path directly, Claude Code only discovers workspace-level skills in .claude/skills/. Therefore, you must create a symlink .claude/skills pointing to ../.agents/skills for Claude Code to discover them.
   • Global: add -g; the CLI installs to the canonical ~/.agents/skills/ and automatically links it to each agent's global directory:
     • Antigravity: ~/.gemini/antigravity-cli/skills/
     • OpenCode: ~/.config/opencode/skills/
     • Claude: ~/.claude/skills/
3. Install:

   skills add <owner/repo> --skill <name> -y   # one skill
   skills add <owner/repo> --all -y            # whole bundle
   skills add <owner/repo> --all -g -y         # global
   

   The CLI auto-discovers SKILL.md folders (repo root or a skills/ subdirectory); there is no --path flag.
4. Verify:
   • Antigravity: Start an agy session to auto-discover.
   • OpenCode: Prompt "List available skills" in the TUI.
   • Claude: Start a claude session to auto-discover.

Gotchas

1. Scope Conflicts: Workspace skills override global skills of the same name.
2. Structure: A skill folder must contain SKILL.md at its root with valid frontmatter.
3. Antigravity + Symlinks: Antigravity does not yet discover symlinked global skills (vercel-labs/skills#633). For global installs targeting Antigravity, add --copy, e.g. skills add <owner/repo> --all -g -a antigravity --copy -y.
4. Claude workspace skills: Because Claude Code only discovers workspace-level skills in .claude/skills/, a symlink must be created to link the standard .agents/skills/ directory to .claude/skills/ (i.e., mkdir -p .claude && ln -s ../.agents/skills .claude/skills).
