command-executor

A command-execution skill that provides a standard process for checking the operating system before running commands. Its description does not specify which commands it supports.

In plain words
What is it for?
Use it as a starting procedure for command-line work when the operating system needs to be detected first.
Why use it?
Checking the operating system first can help avoid using instructions that do not fit the user's computer.

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

command-executor scanned grade D with 3 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 2d 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.

Asks for rootmediumPrivilege escalation

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

| Ubuntu/Debian | apt | `sudo apt install jq` |

Recursive force deletehighDestructive command

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

| 删除目录 | `rm -rf dir` | `rmdir /s /q dir` | `Remove-Item -Recurse dir` |

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.

command-executor is a skill published in the GitHub repository langhuihui/vibe (11 stars, last pushed 4mo ago), with no licence file. It costs nothing until one of its globs matches a file; then it loads 4,859 tokens. A static security scan graded it D with 3 findings (asks for root, recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
