README

grok-skills

Run [Grok](https://x.ai) from Claude Code or Codex (the ChatGPT desktop coding surface) as a second pair of hands: review, reason, implement directly in your tree (default) or in an isolated worktree, verify. Not affiliated with xAI.

Works on whatever repo you point it at. The install location of this package is not the repo under review.

Plugin name: `grok`. Claude Code and Codex both install the same package; they **invoke** skills differently (table below).

**Division of labor:** Claude Code or Codex = orchestrator. Grok (via this plugin) = sandboxed second mind - especially **`grok-engineer-coder`** for implementation directly in your tree (default) or in an isolated worktree. How edits land is mode-aware: [plugin/references/integration-modes.md](plugin/references/integration-modes.md).

First 5 minutes

Install **Grok CLI**, log in, confirm `grok --version` works (macOS or Linux for live modes; Python 3 + Node on `PATH`). Any working Grok CLI build is accepted - there is no exact version lock.
Add the marketplace and install the plugin (no manual clone needed):
```
# Claude Code (in-session or CLI)
/plugin marketplace add sfourdrinier/grok-skills
/plugin install grok@grok-skills
```
```
# Codex CLI
codex plugin marketplace add sfourdrinier/grok-skills
codex plugin add grok@grok-skills
```
Full URL `https://github.com/sfourdrinier/grok-skills.git` works too; GitHub shorthand is equivalent. Then `/reload-plugins` (Claude) or start a new session (Codex custom agents: run `/grok:setup` once; untrusted SessionStart does not install them).
Optional readiness check:
```
/grok:setup
```
For **background completion signals** (OS toast / webhook when a job finishes while you are not watching), enable auto and run live skills in the background with the execution-context env set by the skill (see [execution-context.md](plugin/references/execution-context.md
