# Install Performance Optimization in Google Antigravity

Safety review (2026-10-15): One Markdown guide with measure-first workflow and examples; nothing to run, no network, no keys.

## 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. Download the repository

```bash
git clone --depth 1 https://github.com/sickn33/antigravity-awesome-skills.git /tmp/ag-skills && git -C /tmp/ag-skills log -1 --format=%h
```

   We reviewed commit a307264. If the second command prints a different hash, the skill may have changed since our review.
2. Copy the skill into this project (workspace skill)

```bash
mkdir -p .agents/skills && cp -r /tmp/ag-skills/skills/performance-optimization .agents/skills/
```

   Run from your project root. Antigravity reads workspace skills from .agents/skills/<folder>/; this folder holds just SKILL.md (1 file, no scripts).
3. Or install it for all projects (global skill)

```bash
mkdir -p ~/.gemini/config/skills && cp -r /tmp/ag-skills/skills/performance-optimization ~/.gemini/config/skills/
```

   Use this instead of the previous step. Copy only the skills you need: the repo README warns that a large watched skills folder can overload Antigravity's context.
4. Check that Antigravity sees it
   Antigravity app: start a new conversation and ask "What skills do you have?"; performance-optimization should be listed. Antigravity CLI: run /skills (/skills reload in a session that was already open).

Note: The repository's own installer (npx agentic-awesome-skills --antigravity --skills <ids> --dry-run, README) can also install selected skills; the copy steps above use the standard Antigravity skill folders and install only this one.

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).
