# Install Steam Library in Google Antigravity

Safety review (2026-10-13): Instruction-only skill for a third-party Steam Web API CLI; data goes to Steam with your API key and stays local unless you opt into webhooks or feedback upload.

## 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. Clone the source repo

```bash
git clone --depth 1 --filter=blob:none --sparse https://github.com/mvanhorn/printing-press-library /tmp/printing-press-library && git -C /tmp/printing-press-library sparse-checkout set cli-skills/pp-steam-web
```

   Download the repository that contains the skill into a temporary folder.
2. Copy into this workspace (project skill)

```bash
mkdir -p .agents/skills && cp -r /tmp/printing-press-library/cli-skills/pp-steam-web .agents/skills/pp-steam-web
```

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

```bash
mkdir -p ~/.gemini/config/skills && cp -r /tmp/printing-press-library/cli-skills/pp-steam-web ~/.gemini/config/skills/pp-steam-web
```

   Use this instead of the previous step if you want the skill in every workspace. Antigravity reads global skills from ~/.gemini/config/skills/<folder>/.
4. Check that Antigravity sees it
   Start a new Antigravity agent session in this workspace and ask "What skills do you have?" (in the Antigravity CLI you can also run /skills). The skill should be listed by its name.

Note: Requires steam-web-pp-cli on PATH (npx -y @mvanhorn/printing-press-library install steam-web --cli-only) and STEAM_WEB_API_KEY from https://steamcommunity.com/dev/apikey. The README does not mention Antigravity; this is a plain folder copy into Antigravity's standard skill folders. Ignore the MCP go install line inside the SKILL.md: its library/other/steam-web path does not exist in the repository.

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).
