SHAFT_ENGINE: Agent for Claude Code

.claude/agents/chaos-engine-mechanical-helper.md

chaos-engine-mechanical-helper is an agent for Claude Code from ShaftHQ/SHAFT_ENGINE. It costs 19 tokens per session (83 once invoked), scanned A, original, MIT.

An agent role for carrying out clearly defined, repeatable tasks according to written specifications. It stops when the instructions are unclear.

In plain words
What is it for?
Use it for deterministic, reversible work that must match an exact specification.
Why use it?
It helps keep routine changes predictable and prevents guesses when the requested work is ambiguous.

Agent for Claude Code

Written for Claude Code: installed under .claude/.

This is ShaftHQ/SHAFT_ENGINE's own configuration. It tells Claude Code how to work on SHAFT_ENGINE itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything SHAFT_ENGINE configures →

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

chaos-engine-mechanical-helper 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 9d 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.

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.
