Find the token leaks in Antigravity
Antigravity loads the rules and MCP servers it loads at the start of a run on every run. AgentWitch shows what each one costs, then learns skills and scripts so repeat work costs almost nothing.
1. Get started
Sign in to AgentWitch. The app shows one install command for AgentWitch Local. Paste it into Terminal on the computer where you use Antigravity. No card needed.
2. Connect your assistant
Antigravity connects through AgentWitch Local on your computer.
3. Run the token-leak check
The check lists what Antigravity loads on every run and shows the token cost of each item, with the biggest leaks first.
4. Let skills and scripts take over
When a job repeats, AgentWitch writes it down as a skill or script. Skills and scripts need no approval. Reports show how many tokens each one saved.
Your files, tokens and run history stay on your computer. Savings are estimates per skill, so the report marks small samples with ≈.
