Malicious Rmrf Flags

Malicious Rmrf Flags is a skill for Claude Code, Codex from aeonfun/aeon. It costs 6 tokens per session (38 once invoked), scanned C, original, MIT.

A set of shell commands that recursively deletes system directories such as /etc, /usr, or the root filesystem.

In plain words
What is it for?
It is relevant to testing whether an agent detects destructive shell commands, not to normal development work.
Why use it?
Running these commands can erase operating-system files and make a machine unusable.

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 C, and why

Malicious Rmrf Flags scanned grade C with 1 finding 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 4d 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.

Recursive force deletehighDestructive command

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.
