The author's description, from SKILL.md

Generated summary from the skill's own text

This skill enables agents to control the Antigravity desktop application programmatically via OpenCLI and Chrome DevTools Protocol. Agents can send messages to the chat interface, read conversation history, extract code blocks from responses, switch between language models, and manage conversation state.

When to use it

  • Automating multi-turn conversations with an LLM through the Antigravity UI
  • Extracting generated code from AI responses for further processing
  • Switching between different language models programmatically
  • Scraping chat transcripts or monitoring real-time streaming output

When not to

  • Interacting with APIs directly when Antigravity UI automation is not needed
  • Using Antigravity without Chrome DevTools Protocol enabled

Install

These commands install from the publisher's repository and need no account.

1. Download that folder at exactly this commit. Do not use the default branch.
2. Copy every file unchanged, keeping the folder structure, into .claude/skills/antigravity/ for Claude Code and .agents/skills/antigravity/ for Codex, Cursor, Gemini CLI, GitHub Copilot and OpenCode. Create the folders if they do not exist.
3. Do not edit the files, and do not run any script in the folder unless I ask you to.
4. When you are done, list the files you copied and where you put them.

# Antigravity Automation Skill

This skill allows AI agents to control the [Antigravity](https://github.com/chengazhen/Antigravity) desktop app (and any Electron app with CDP enabled) programmatically via OpenCLI. 

## Requirements
opencli automatically detects, launches (with `--remote-debugging-port=9234`), and connects to Antigravity.
If Antigravity is already running without CDP, opencli will prompt to restart it.

If the endpoint exposes multiple inspectable targets, set:
\`\`\`bash
export OPENCLI_CDP_TARGET="antigravity"
\`\`\`

## High-Level Capabilities
1. **Send Messages (`opencli antigravity send <message>`)**: Type and send a message directly into the chat UI.
2. **Read History (`opencli antigravity read`)**: Scrape the raw chat transcript from the main UI container.
3. **Extract Code (`opencli antigravity extract-code`)**: Automatically isolate and extract source code text blocks from the AI's recent answers.
4. **Switch Models (`opencli antigravity model <name>`)**: Instantly toggle the active LLM (e.g., \`gemini\`, \`claude\`).
5. **Clear Context (`opencli antigravity new`)**: Start a fresh conversation.

## Examples for Automated Workflows

### Generating and Saving Code
\`\`\`bash
opencli antigravity send "Write a python script to fetch HN top stories"
# wait ~10-15 seconds for output to render
opencli antigravity extract-code > hn_fetcher.py
\`\`\`

### Reading Real-time Logs
Agents can run long-running streaming watch instances:
\`\`\`bash
opencli antigravity watch
\`\`\`
