shell-safety-review

shell-safety-review is a skill for Claude Code, Codex from RYOITABASHI/Shelly. It costs 30 tokens per session (515 once invoked), scanned A, original, GPL-3.0.

Eine Sicherheitsprüfung für Shell-Befehle, also Anweisungen, die über ein Terminal mit dem Betriebssystem arbeiten. Sie sucht nach zerstörerischen oder nicht rückgängig zu machenden Folgen, besonders bei unbeaufsichtigten Abläufen.

In plain words
What is it for?
Für einen kurzen Sicherheitscheck von Shell-Befehlen vor manuellen, automatisierten oder autonomen Ausführungen. Besonders geeignet ist sie für Befehle, die Dateien, Verzeichnisse oder andere Systemdaten verändern könnten.
Why use it?
Sie hilft, Befehle vor dem Ausführen auf riskante Nebenwirkungen zu prüfen. Dadurch können versehentliches Löschen oder andere schwer rückgängig zu machende Änderungen früher auffallen.

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

shell-safety-review 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 8d 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 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.
