grok

grok is a skill for Claude Code, Codex from NousResearch/hermes-agent. It costs 18 tokens per session (3,703 once invoked), scanned C, original, MIT.

A skill for sending coding tasks to Grok Build, xAI's command-line coding agent. Grok Build can work with project files, run shell commands, use other agents, and manage Git workflows.

In plain words
What is it for?
Use it to delegate implementation work, code changes, reviews, or issue fixing to Grok Build from a terminal.
Why use it?
It gives you another coding agent to use for features, refactoring, pull-request reviews, or batches of issues. It explains how to run the tool interactively or without prompts and how to authenticate it.

  • high Supply Chain · line 37
    Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.
    Fix: Avoid downloading and executing remote scripts. Use trusted packages from PyPI/npm. If remote fetch is required, verify checksums and use HTTPS.
  • high Tool Misuse · line 233
    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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 26d 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.

grok is a skill published in the GitHub repository NousResearch/hermes-agent (254,120 stars, last pushed today), licensed MIT. It adds 18 tokens to every session and 3,703 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
