Agent Prompt: Bash command description writer

Agent Prompt: Bash command description writer is an agent for coding agents from openonion/connectonion. It costs 22 tokens per session (220 once invoked), scanned C, original, Apache-2.0.

Instructions for writing short, active descriptions of shell commands. They explain how much detail to use for common commands and harder-to-read commands with pipes or special options.

In plain words
What is it for?
Describing commands such as Git, npm, file searches, deletion commands, and data-processing pipelines.
Why use it?
It makes command descriptions easier to understand at a glance, especially when a command could be misread.

About the project

ConnectOnion is an open-source, template-first toolkit for building, debugging, deploying, and operating AI agents. Developers use its command-line tools and Python runtime to create agents, add tools, connect services, deploy them, and make them callable by other agents, while the catalogue entries are related agents, skills, and instructions.

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

Agent Prompt: Bash command description writer scanned grade C 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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

What it actually says

Clear, concise description of what this command does in active voice. Never use words like "complex" or "risk" in the description - just describe what it does.

For simple commands (git, npm, standard CLI tools), keep it brief (5-10 words):

  • ls → "List files in current directory"
  • git status → "Show working tree status"
  • npm install → "Install package dependencies"

For commands that are harder to parse at a glance (piped commands, obscure flags, etc.), add enough context to clarify what it does:

  • find . -name "*.tmp" -exec rm {} ; → "Find and delete all .tmp files recursively"
  • git reset --hard origin/main → "Discard all local changes and match remote main"
  • curl -s url | jq '.data[]' → "Fetch JSON from URL and extract data array elements"

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.
