System Administration

System Administration is a skill for Claude Code, Codex from turmyshevd/openclawgotchi. It costs 14 tokens per session (920 once invoked), scanned D, original, MIT.

A set of instructions for administering a Raspberry Pi Zero 2W, a small single-board computer. It covers power controls, services, system health, networking, processes, and backups.

In plain words
What is it for?
Use it to reboot or shut down the Pi, manage services, view logs, check temperature, memory, storage, network details, running processes, and database backups.
Why use it?
It puts common maintenance commands in one place, so you do not need to remember how to inspect or control the device.

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 D, and why

System Administration scanned grade D 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 5d 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.

A mod that escalates privileges can change anything on the machine, not only the project.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

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.

System Administration is a skill published in the GitHub repository turmyshevd/openclawgotchi (48 stars, last pushed 2mo ago), licensed MIT. It adds 14 tokens to every session and 920 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it D with 2 findings (asks for root, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
