# Install Calendar Management in Google Antigravity

Source: https://github.com/openclaw/openclaw/tree/main/skills/gog

Safety review (2026-10-21): Medium risk: Markdown-only skill, but it drives an external CLI with your Google OAuth tokens that can send email and edit files if you grant those scopes.

## Rules for the agent
- Before running anything, tell the user what you will download and whether it contains scripts, and ask them to confirm.
- Install into this project (.agents/skills/) unless the user asks for a global install (~/.gemini/config/skills/).
- Do not run other commands from the source repository unless the user asks.

## Steps
1. Install the gog CLI

```bash
brew install gogcli
```

   The skill's metadata lists the Homebrew formula gogcli, which provides the gog binary. See gogcli.sh for other platforms.
2. Clone the skill folder

```bash
git clone --depth 1 --filter=blob:none --sparse https://github.com/openclaw/openclaw /tmp/openclaw && git -C /tmp/openclaw sparse-checkout set skills/gog
```

   A sparse clone fetches only the skill folder from the large OpenClaw repository.
3. Copy into your workspace (this project only)

```bash
mkdir -p .agents/skills && cp -r /tmp/openclaw/skills/gog .agents/skills/gog
```

   Run this from your project root. Antigravity reads workspace skills from <project>/.agents/skills/<folder>/.
4. Or copy globally (all projects)

```bash
mkdir -p ~/.gemini/config/skills && cp -r /tmp/openclaw/skills/gog ~/.gemini/config/skills/gog
```

   Use this instead of the workspace step if you want the skill in every project. Antigravity reads global skills from ~/.gemini/config/skills/<folder>/.
5. Authorize Google once

```bash
gog auth credentials /path/to/client_secret.json && gog auth add you@gmail.com --services calendar
```

   Run this yourself in a terminal. Add other services (gmail, drive, contacts, docs, sheets) only if you want the agent to use them.
6. Check that Antigravity sees it
   Start a new agent session and ask "What skills do you have?" (in the Antigravity CLI you can also run /skills). The skill should appear as gog.

Note: The OpenClaw README does not mention Antigravity, so this is a manual copy. Needs the gog binary and your own Google OAuth client credentials. Set GOG_ACCOUNT=you@gmail.com to avoid repeating --account. Never paste client secrets or refresh tokens into the chat; the skill tells the agent not to ask for them.

Done when the skill is listed: in the Antigravity 2.0 app ask "What skills do you have?" in a new conversation (the app has no /skills command); in the Antigravity CLI run /skills (run /skills reload first in a session that was already open).
