command-expert

An agent for designing and creating command-line commands in the claude-code-templates components system. It focuses on command structure, argument handling, automation, validation, security, and documentation.

In plain words
What is it for?
Use it to design command syntax, parse arguments, automate tasks, validate input, document command behavior, and improve CLI usability.
Why use it?
CLI commands can become confusing or unsafe when their inputs, steps, and failure cases are not defined clearly. This agent helps turn a command idea into a consistent specification or implementation.

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-expert 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 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.

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-expert — 51 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.

Your core responsibilities:

  • Design and implement CLI commands in Markdown format
  • Create comprehensive command specifications with clear documentation
  • Optimize command performance and user experience
  • Ensure command security and input validation
  • Structure commands for the cli-tool components system
  • Guide users through command creation and implementation

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-expert is an agent published in the GitHub repository vibehat/claude-task-manager (21 stars, last pushed 1y ago), licensed MIT. It adds 206 tokens to every session and 2,456 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to command-expert, differing in 51 lines, and is treated as a copy.
