Burn-Rate Charts and a Cache Janitor for Antigravity

What it does

Toolkit for Antigravity is a companion extension for Google’s Antigravity IDE that surfaces real-time AI quota usage, visualizes consumption trends, and lets you purge conversation and code caches without leaving the editor. It also bundles a hands-free auto-accept mode for agent commands and a commit-message generator powered by local LLMs or Claude.

The interesting bit

The extension reads internal metrics from the local Antigravity environment to chart your remaining Gemini, Claude, or GPT quota and predicts how long until you hit the limit. If the IDE’s sandboxed webview blocks the standard command API, it falls back to CDP injection to auto-accept agent suggestions.

Key highlights

• Quota dashboard with pie charts, status-bar emoji thresholds (🟢🟡🔴), and a “runway” timer estimating time-to-exhaustion.
• Cache manager for “Brain Tasks” and per-project code context, with one-click deletion and automatic tab cleanup.
• Auto-accept mode that uses a command API first, then falls back to CDP injection if the IDE is launched with --remote-debugging-port=9222.
• Commit-message generator that diffs staged changes through a local LLM or sends them to Anthropic’s Claude API.
• Localized UI in 13 languages and built-in service-recovery commands (restart language server, reset user status, reload window).

Caveats

• Smart quota monitoring is explicitly marked experimental because it relies on internal metrics exposed by the local Antigravity environment; if Google changes those internals, the dashboard breaks.
• The hands-free CDP fallback only works if you launch Antigravity with --remote-debugging-port=9222, which is an extra setup step and a potential security surface.
• The Claude commit-generator option transmits your staged diff to Anthropic’s API; the default local-LLM path keeps data on your machine, but switching models requires conscious opt-in.

Verdict

Grab it if you live in Antigravity IDE and are tired of guessing when your GPT or Claude quota will flatline. Skip it if you don’t use Google’s IDE or prefer your commit messages handwritten and your agent prompts manually approved.
