CodeRabbit Plugin for Antigravity

Run CodeRabbit reviews from Antigravity, understand the findings, and fix issues within your requested scope. The plugin also provides a separate workflow for unresolved CodeRabbit feedback on existing GitHub pull requests.

Status

Initial package, version 0.1.0. The repository has package validation, regression tests, and reproducible upstream imports. Loading and running the plugin in Antigravity still requires the smoke test. Marketplace review and publication are pending.

Requirements

• Google Antigravity with native plugin support.
• Git and a project in an initialized Git repository.
• CodeRabbit CLI installed from an official source and authenticated in the environment where the review runs.
• GitHub CLI (gh) authenticated for existing GitHub PR autofix workflows.

CodeRabbit reviews send the selected code diff to the CodeRabbit API. Use the review scope you intend to share, and exclude secrets. The plugin does not include an MCP server or automatically install software.

Install

Clone this repository and install the local package with Antigravity CLI:

git clone https://github.com/coderabbitai/antigravity-plugin.git
cd antigravity-plugin
agy plugin install .
agy plugin list

Confirm that coderabbit appears with the two skills, agents, and routing rule. Reload your Antigravity session if the components are not visible immediately.

For the standalone Antigravity IDE, clone the package to a workspace plugin folder:

git clone https://github.com/coderabbitai/antigravity-plugin.git .agents/plugins/coderabbit

For all IDE workspaces, use ~/.gemini/config/plugins/coderabbit instead. Inspect the loaded components through the agent panel's Customizations menu. Install at one scope initially to avoid duplicate components.

These paths follow Google's plugin installation documentation. Local installation does not add the plugin to the Marketplace.

Use

Ask the agent naturally:

Use CodeRabbit to review my changes.
Review my uncommitted changes, including new untracked files.
Review this branch against main with CodeRabbit.
Build this feature, review it with CodeRabbit, fix the confirmed issues, and review again.
Show unresolved CodeRabbit feedback on this PR and propose fixes.

Antigravity converts skill names into slash commands. The bundled skills expose:

/coderabbit-review
/coderabbit-autofix

See Google's skill invocation documentation.

Local coding, review, and fix

The review skill checks the selected repository and authentication, then runs the trusted CodeRabbit CLI with review --agent and the requested scope. It reports the findings at their original severity. If you request fixes, the agent checks the code, applies authorized changes, and runs relevant validation. Review loops use your run limit or at most three review invocations per change set.

A failed, skipped, interrupted, or partial review is reported with its limitation. It is not reported as a clean review. If login is needed, complete it in your terminal; the plugin never reads or copies your credentials.

Existing GitHub PR feedback

The autofix skill requires a clean worktree and local HEAD matching the exact PR head, with a submitted CodeRabbit review for that commit. It fetches current, unresolved threads, checks each issue locally, and presents proposed changes for per-fix approval. Pushes and PR comments follow your explicit authorization.

Use --no-commit in your request to keep approved fixes local and uncommitted. This workflow does not create a new PR or automatically publish comments.

The root manifest uses Antigravity's format. Branding and package version live in this README and development metadata, rather than unsupported manifest fields. Skills and agents are adapted from pinned CodeRabbit sources. See upstream maintenance.

Development and Marketplace submission

npm ci
npm run check
npm run package

Node.js 22 or newer is needed for development. Python 3 creates a deterministic ZIP in dist/ with plugin.json at its root. Antigravity users do not need Node or Python merely to load these Markdown components.

The checks validate package files and references; they do not replace testing actual discovery, authentication, review output, and fixes in Antigravity. Follow the smoke test and Marketplace submission guide before a release.
