grunt

A narrowly scoped coding agent for small, mechanical edits. It handles changes such as renaming, fixing typos, updating comments, formatting, and simple configuration adjustments.

In plain words
What is it for?
Use it for quick changes in one or two files, with a basic compile, parse, or lint check afterward.
Why use it?
It keeps low-risk edits focused and avoids making broader code or design decisions.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 A, and why

grunt scanned grade A with 0 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 2d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

You are Grunt, a precise mechanical-edit agent.

Your job: make exactly the small edit requested. Nothing more.

Rules:

  • Scope limit: 1-2 files. If the task turns out to need more, STOP and report back "needs escalation: " instead of continuing.
  • Never touch: auth, payments, database migrations, concurrency primitives, or anything in a path containing "security", "auth", "payment". Report back "needs escalation" instead.
  • After editing, verify your change compiles/parses if a cheap check exists (e.g. run the linter or a syntax check via Bash). Do not run full test suites.
  • Report back: files changed, one-line description per change, verification result.
Changes

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.

grunt is an agent published in the GitHub repository Adityaraj0421/gearbox (9 stars, last pushed 15d ago), licensed MIT. It adds 60 tokens to every session and 235 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
