grok

grok is a skill for Codex from aivrar/portable-hermes-agent. It costs 18 tokens per session (3,667 once invoked), scanned C, a copy of grok, MIT.

A wrapper that sends coding tasks to xAI's Grok Build command-line tool, an autonomous coding assistant that can work with files, shell commands, subagents, and Git workflows.

In plain words
What is it for?
Use it to delegate coding tasks to Grok Build from a terminal, either as one-off commands, interactive sessions, or an agent connected through JSON-RPC.
Why use it?
It gives you another coding-agent option for feature work, refactoring, pull-request reviews, and batches of issue fixes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

grok scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Grok Build CLI — Hermes Orchestration Guide

Delegate coding tasks to Grok Build (xAI's autonomous coding agent CLI, the grok command) via the Hermes terminal. Grok can read files, write code, run shell commands, spawn subagents, and manage git workflows. It runs three ways: an interactive TUI, headless (-p), and as an ACP agent over JSON-RPC.

This is the third sibling to codex and claude-code. The orchestration pattern is nearly identical — prefer headless -p for one-shots, use a PTY for interactive sessions.

When to use

  • Building features
  • Refactoring
  • PR reviews
  • Batch issue fixing
  • Any task where you'd otherwise reach for Codex / Claude Code but want Grok

Prerequisites

  • Install (preferred): npm install -g @xai-official/grok
    • The official installer curl -fsSL https://x.ai/cli/install.sh | bash also works, but the x.ai host is Cloudflare-walled in some environments. The npm path avoids that dependency entirely.
  • Auth — SuperGrok / X Premium+ subscription (primary path):
    • Run grok login once → opens a browser for OAuth → token cached in ~/.grok/auth.json. This uses your SuperGrok or X Premium+ subscription (no per-token API billing).
    • Check sign-in state by looking for ~/.grok/auth.json, or run a cheap headless smoke test: grok --no-auto-update -p "Say ok."
    • In the TUI, /logout signs out and /login (or relaunching) signs back in.
  • No git repo required — unlike Codex, Grok runs fine outside a git directory (good for scratch/throwaway tasks).
  • Claude Code / AGENTS.md compatible with zero config — Grok auto-reads CLAUDE.md, .claude/ (skills, agents, MCPs, hooks, rules), and the AGENTS.md family. Existing project context just works.

API-key fallback (not the default for this user): Grok also supports setting the XAI_API_KEY environment variable for pay-as-you-go billing via api.x.ai. Only use this if grok login / SuperGrok auth is unavailable. The subscription path (grok login) is the intended setup here.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
