Heinzel — System Administration with Safety Guardrails Heinzel is a set of rules that turns an AI coding assistant into a cautious, methodical sysadmin. It works with Claude Code, OpenCode, or any other terminal-based AI tool that can read project files and run shell commands. It manages Linux, FreeBSD, and macOS targets — remote servers over SSH and the local machine alike — and runs on any workstation where your AI tool runs, including Windows (via WSL or natively). Describe what you need in plain English, and Heinzel figures out the right commands for your OS, proposes each one with an explanation, and waits for your approval before running anything. It backs up configs, tests commands before real execution, remembers every server it has worked on, and gives you a detailed report when it's finished. Using it feels like pair-programming with a colleague who always checks the docs first and never skips a step because he's in a hurry. The bigger the network, the more it pays off — Heinzel remembers every server's OS, services, and quirks so you don't have to. Not sure yet? Ask Heinzel to plan first before making changes — no changes until you say go.

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.
The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
