Use an Antigravity build that supports the partner marketplace manifest format. Clone the repository and run the commands from its root:
git clone https://github.com/linear/antigravity-plugin.git
cd antigravity-plugin
agy plugin validate .
agy plugin install .
agy plugin listIf you already have a local checkout, run agy plugin validate . and
agy plugin install . from its root; no additional clone is needed.
After installation, follow the account connection steps in README.md.

The server implementation and credentials are not part of this package.
This package follows the partner publishing guide's marketplace manifest format. The public plugin documentation currently describes a smaller schema, so validate with the intended partner build before submission. The public schema URL is deliberately omitted from the manifest because that schema rejects the additional marketplace fields.
Before publishing:
- Run
agy plugin validate .and install the package with the intended Antigravity build. Confirm the logo, display name, and three starter prompts render correctly on light and dark themes. - Complete a fresh Linear OAuth sign-in and verify that Linear tools appear.
- Ask Antigravity to list your assigned issues, then read a known issue and verify its identifier, title, and description against Linear.
- Restart Antigravity and repeat the read. Reconnect and verify sign-in recovery if the connection is disconnected or expired.
- Confirm repository visibility and submission requirements with the Google marketplace contact before submitting. Increment the manifest version for subsequent published updates.
JSON and asset checks alone do not verify Antigravity installation, OAuth, tool discovery, or reconnection. Record those results with the tested build before release.
