Antigravity Skills & Extended Tooling

Antigravity Skills & Extended Tooling is an open-source, MIT-licensed collection of skill extensions for Google Antigravity (agy), published by MaDxCRaZY. It exposes four slash commands, /owl, /battle, /benchmark and /compaction, covering investigation, adversarial comparison, empirical benchmarking and context compaction.

What It Is

The repository packages agent workflows as installable skills for the Antigravity IDE and CLI. Each skill is invoked from the chat input as a slash command and runs a defined multi-step pipeline instead of a single-pass answer. Skills install either globally or into a single workspace.

How the Commands Work

• /owl splits a task between a DeepInvestigator, which audits call trees, object lifecycles and edge-case hypotheses, and a DeepCoder, which implements the fix against compiler and test gates.
• /battle forks two rival subagents into isolated git worktrees, has an adversarial referee (critic@colosseum) stress-test both, then merges the winning branch.
• /benchmark generates a standalone micro-benchmark harness in a scratch workspace and runs it headlessly. It reports p50/p99 latency, throughput and peak memory (RSS) in a side-by-side comparison.
• /compaction extracts active state such as file paths, struct layouts, verified hypotheses and next steps into persistent markdown artifacts, then prunes transient logs and resets the context.

Setup Path

Inside an Antigravity session, users can paste a one-prompt install request and the agent clones the repo and deploys the skills to ~/.gemini/config/skills/. Manual installation uses the included install.ps1 (Windows PowerShell) or install.sh (Linux/macOS). A -LocalWorkspace option on the PowerShell installer deploys into .agents/skills/ for one repository. After installation, reload the IDE or start a new CLI session and type / to confirm the commands appear.
