skill-installer

# Skill Installer Helps install skills. By default these are from https://github.com/openai/skills/tree/main/skills/.curated, but users can also provide other locations. Use the helper scripts based on the task: - List curated skills when the user asks what is available, or if the user uses this skill without specifying what to do. - Install from the curated list when the user provides a skill name. - Install from another repo when the user provides a GitHub repo/path (including private repos). Install skills with the helper scripts. ## Communication When listing curated skills, output approximately as follows, depending on the context of the user's request: """ Skills from {repo}: 1. skill-1 2. skill-2 (already installed) 3. ... Which ones would you like installed? """ After installing a skill, tell the user: "Restart Antigravity to pick up new skills." ## Scripts All of these scripts use network, so when running in the sandbox, request escalation when running them. - `scripts/list-curated-skills.py` (prints curated list with installed annotations) - `scripts/list-curated-skills.py --format json` - `scripts/install-skill-from-github.py --repo <owner>/<repo> --path <path/to/skill> [--global]` - `scripts/install-skill-from-github.py --url https://github.com/<owner>/<repo>/tree/<ref>/<path> [--global]` ## Behavior and Options - Defaults to direct download for public GitHub repos. - If download fails with auth/permission errors, falls back to git sparse checkout. - Aborts if the destination skill directory already exists. - Default Location: Installs into the workspace-specific skills directory `<workspace-root>/.agent/skills/<skill-name>`. - Global Location: Use the `--global` flag to install into the global directory `~/.gemini/antigravity/skills/<skill-name>`. - Multiple `--path` values install multiple skills in one run, each named from the path basename unless `--name` is supplied. - Options: `--ref <ref>` (default `main`), `--dest <path>`, `--method auto|download|git`, `--global`. ## Notes - Curated listing is fetched from `https://github.com/openai/skills/tree/main/skills/.curated` via the GitHub API. If it is unavailable, explain the error and exit. - Private GitHub repos can be accessed via existing git credentials or optional `GITHUB_TOKEN`/`GH_TOKEN` for download. - Git fallback tries HTTPS first, then SSH. - The skills at https://github.com/openai/skills/tree/main/skills/.system are preinstalled, so no need to help users install those. If they ask, just explain this. If they insist, you can download and overwrite. - Installed annotations come from both the global skills directory `~/.gemini/antigravity/skills` and current workspace skills directory `<workspace-root>/.agent/skills`.
