antigravity-panel

Antigravity Panel is a VS Code extension that monitors AI quota usage (Gemini, Claude, GPT) within Google's Antigravity IDE, displays consumption trends, and manages conversation cache. It supports 14 languages and includes hands-free command auto-accept and AI commit generation.

What antigravity-panel is

TypeScript-based VS Code extension providing real-time quota monitoring via visual dashboards, historical usage analytics with 24-hour persistence, cache management for Brain Tasks and Code Context, optional Claude API integration for commit generation, and fallback Chrome DevTools Protocol (CDP) for command injection when sandboxed.

Best use cases

AI-Assisted Development Workflow Optimization

Teams using Antigravity IDE for AI-paired coding can monitor Gemini/Claude/GPT quota consumption in real-time, predict runway before exhaustion, and optimize spend without manual tracking across multiple model APIs.

Conversation Cache Lifecycle Management

Developers managing large AI conversation histories can browse, preview, and selectively delete Brain Task caches and code context caches within the IDE, reducing storage overhead and improving IDE performance.

High-Volume Agent Workflows

Teams running autonomous agent commands (terminal/file edits) via Antigravity can enable hands-free auto-accept mode to eliminate approval bottlenecks while monitoring quota impact via real-time trends and thresholds.

Implementation considerations

Verify Antigravity IDE is installed and running; extension requires active Antigravity context to initialize quota monitoring and cache APIs.
For hands-free auto-accept (fallback mode), launch Antigravity with `--remote-debugging-port=9222`; ensure no other instances are running to avoid CDP port conflicts.
If using Claude commit generation, securely store Anthropic API key via `Antigravity Panel: Set Anthropic API Key` command; key is stored in VS Code Secrets API (not plaintext).
Configure quota warning/critical thresholds (default 40%/20%) based on team spending policy; check Settings → Antigravity Panel → Thresholds.
24-hour usage history persists locally; clear extension data if switching Antigravity accounts or migrating machines to avoid stale quota readings.

When to avoid it — and what to weigh

Not Using Antigravity IDE — This extension is purpose-built for Google Antigravity IDE; it provides no value in standard VS Code or other IDEs and will not function without Antigravity runtime.
Closed Source / Air-Gapped Environments — Hands-free mode with fallback CDP requires Antigravity launched with `--remote-debugging-port=9222`; auto-accept features may not work reliably in sandboxed or restricted deployments without debugging port access.
Minimal AI Model Usage — If your team uses Antigravity infrequently or has unlimited quota, quota monitoring and runway prediction add little operational value; the extension is overhead for light-touch AI integration.
Legacy Antigravity Versions — Compatibility with older Antigravity IDE versions is not documented; installation may fail or behave unpredictably if your Antigravity build is significantly behind the current release cycle.

Security considerations

Extension stores Anthropic API key via VS Code Secrets API (encrypted at rest, not plaintext). Commit generation sends staged diffs to configured LLM endpoint; use local Ollama to avoid external exposure of code. Auto-accept mode requires debugging port; restrict `--remote-debugging-port=9222` to trusted networks. Conversation cache deletion is permanent; no recovery mechanism. Review Google Antigravity IDE's security posture independently.

Alternatives to consider

Native Antigravity IDE Built-in Quota Monitoring

Antigravity IDE may include native quota display; if sufficient for your needs, eliminates extension dependency and reduces attack surface.

Third-Party AI Cost Management Platforms (e.g., Arize, Humanloop)

Centralized platforms offer quota tracking and analytics across multiple IDEs and models; better for multi-tool environments, though may not integrate directly with Antigravity IDE.

Manual Script-Based Quota Polling

Teams preferring full control can write custom scripts querying Antigravity APIs directly; avoids extension maintenance but requires engineering effort and in-house support.

antigravity-panel FAQ

Can I use Antigravity Panel without Google Antigravity IDE?

No. The extension is purpose-built for Antigravity IDE and will not function in standard VS Code or other editors.

Is my Anthropic API key safe?

Yes. The key is stored in VS Code's Secrets API (encrypted at rest) and never written to plaintext files. However, diffs sent to external LLM endpoints are not encrypted in transit; use a local Ollama endpoint if code confidentiality is critical.

What happens if I delete a Brain Task cache?

Deletion is permanent: the conversation history and associated artifacts are removed from Antigravity's cache. Related editor tabs close automatically. No recovery mechanism is available.

Do I need CDP debugging enabled for auto-accept to work?

Not always. Auto-accept first tries the command API (primary method). CDP fallback with `--remote-debugging-port=9222` is only needed if Antigravity's webview is sandboxed and the command API is unavailable.
