command-execution

A set of safety and efficiency rules for running shell commands. Shell commands are text instructions used to work with files, programs, and the operating system.

In plain words
What is it for?
Use it when planning command-line work, choosing whether to chain commands, verifying what happened, and documenting commands and their outcomes.
Why use it?
It helps decide when to run commands individually, combine related commands, or split complex work into steps. It also requires checking and recording the results.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

command-execution 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 yesterday.

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.

Origin

This is a copy

100% identical to command-execution — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

COMMAND EXECUTION SYSTEM

TL;DR: This system provides guidelines for efficient command execution, balancing clarity and token optimization through appropriate command chaining, with proper documentation of commands and results.

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-execution is a cursor rule published in the GitHub repository Zenobia0000/cursor-agentic-coding-template (5 stars, last pushed 4mo ago), licensed MIT. It adds 12 tokens to every session and 1,237 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to command-execution, differing in 0 lines, and is treated as a copy.
