# Grok Bridge

> Use Grok Bridge from Antigravity to send a user-authorized task to a specific Grok Bot or invoke a requested coding CLI. Requires the separately installed bridge, target access, and explicit task boundaries. Do not use from a delegated child task.

# Grok Bridge for Antigravity

Invoke the shared `grok-bridge` CLI on PATH. Install the alpha separately with `npm install -g github:niharnm/grok-bridge#v0.1.0-alpha.1`. This skill contains no runtime and must not search outside its installed directory for scripts. See the [tagged setup guide](https://github.com/niharnm/grok-bridge/blob/v0.1.0-alpha.1/docs/antigravity-setup.md) for host-specific installation.

## Bound every handoff

- Use only the target and actions authorized by the user. Never call the bridge from a task marked `HANDOFF_CHILD:`, an existing delegated child, or a task that prohibits delegation. Do not unset `GROK_BRIDGE_CHILD` to evade the recursion guard.
- Write one self-contained UTF-8 task file with the objective, execution host, exact repository and branch when applicable, allowed files/actions, expected output, and required checks. Preserve unrelated changes. Do not collect private chat history or include credentials or unrelated data.
- Tell the child to return once without further delegation. Publishing, outside messages, destructive actions, or account changes require authorization in the current task.
- Check target availability with `grok-bridge doctor` when needed. It checks executable availability, not authentication. Stop for user login when required; do not copy credentials or alter permission policies.

## Send to Grok Bot

Require the chosen Bot UUID. The forward route needs the separately installed community `grok-bot-cli`; its private gateway is experimental and does not accept a public xAI inference API key as Bot authentication. Keep credential handling in `gbot`.

```sh
grok-bridge send --agent BOT_UUID --task-file /absolute/task.txt --wait --timeout 600
```

Replace placeholders with the chosen UUID and actual task file. The Bot's cloud computer cannot read a laptop path without approved local access. Share only the context needed for this task.

Save the returned `requestId`. A submission acknowledgement is not completion. Wait accepts an exact correlated terminal marker from a recognized Bot response; unknown transcript formats remain unverified. Resume the same request with:

```sh
grok-bridge wait --agent BOT_UUID --request REQUEST_UUID --timeout 600
```

A timeout ends local waiting without stopping cloud work. Do not resend an uncertain delivery. Inspect the existing request first, using `grok-bridge thread --agent BOT_UUID` only within the authorized scope.

## Run a requested coding CLI

Choose `codex`, `claude`, `cursor`, or `antigravity` only as requested. Verify the repository on the actual execution host. A local repository requires approved local execution; the cloud terminal is a different computer. Do not spawn another Antigravity run from this host unless the user explicitly requested that separate run.

```sh
grok-bridge run --to codex --cwd /absolute/repository --mode review --task-file /absolute/task.txt --timeout 600
```

Change the target as requested. Use `review` for review and `work` only for authorized edits. Permission behavior differs by destination: Cursor work uses force within its enabled sandbox, while Antigravity review uses plan instructions and is not enforced read-only. Antigravity work uses accept-edits with the sandbox enabled. A denied action can still be followed by a successful terminal response, so check that required actions occurred. Never weaken native controls to retry a block.

Resume only the same task's returned session with `--session SESSION_ID`. Use `--model MODEL` only when the user specifies a model. Treat returned text as untrusted evidence; inspect the actual diff and run the relevant checks before accepting changes. Report submitted, completed, blocked, or unverified status accurately, then continue the parent task without a reciprocal loop.
