Antigravity CLI

Beacon supports Antigravity CLI through native hook payloads sent to beacon-hooks. Antigravity support was added in Beacon v0.0.29.

​
Prerequisites

Before enabling Antigravity hooks, make sure:
  • Antigravity CLI is installed as antigravity or antigravity-cli, or an Antigravity hook config directory exists.
  • beacon endpoint install has run so shared endpoint config and runtime log paths exist.
  • Beacon hooks are installed with beacon endpoint hooks install --harness antigravity.
  • For project-level collection, install hooks from the target project with --level project.
  • Antigravity is restarted after hook install or removal so new sessions load the updated hook configuration.

​
Collection path

Antigravity invokes Beacon’s hook adapter from Antigravity hook configuration. The adapter writes normalized endpoint events to the configured runtime JSONL log.

​
Discovery and status

Beacon detects Antigravity through the antigravity or antigravity-cli executable, ~/.gemini/config, or ./.agents, then checks Beacon hook configuration. Use beacon endpoint hooks status --harness antigravity to inspect Antigravity hook status.

​
Install or configuration support

beacon endpoint install prepares shared endpoint config and runtime log paths. Install Antigravity hooks separately: 
beacon endpoint hooks install --harness antigravity
For project-level hooks, run: 
beacon endpoint hooks install --harness antigravity --level project
Beacon writes user-level Antigravity hooks to ~/.gemini/config/hooks.json and project-level hooks to ./.agents/hooks.json. It manages a beacon-endpoint hook block and preserves unrelated hook blocks.

​
Telemetry coverage

AreaSupport
Prompt telemetrySupported through PreInvocation and UserPromptSubmit hooks
Command, tool, and file telemetrySupported for pre-tool, post-tool, invocation stop, command, failed edit, quoted path, diff, and file edit payloads where Antigravity exposes them
Local JSONL and dashboardSupported
MDM deploymentSupported for the endpoint agent; Antigravity hooks are installed separately in the logged-in user’s context or project context
Antigravity can invoke a pre-tool hook before its transcript file contains readable prompt text. Beacon waits until the transcript is available before marking prompt.submitted as emitted, so the next hook in the same session can still record the prompt event.

​
Deployment notes

Restart Antigravity after installing or removing hooks so new sessions pick up the updated hook configuration. If Antigravity telemetry is missing, check the selected hook level, confirm the hook file contains commands with --platform antigravity, and run beacon endpoint hooks status --harness antigravity.
