mq cli.instructions.md

Project-specific rules for building the command-line interface of mq, a tool that queries Markdown files from a terminal. It covers argument parsing, errors, help text, output, and integration tests.

In plain words
What is it for?
Adding commands, flags, and options; handling malformed Markdown or arguments; documenting CLI usage; and testing terminal behavior.
Why use it?
It keeps command-line behavior consistent and makes the tool easier to use, automate, and test when input is invalid.

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

mq cli.instructions.md 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.

What it actually says

CLI Tool Coding Rules

  • All command-line interface logic must reside in mq-run.
  • Use clap or similar crate for argument parsing.
  • Provide clear, user-friendly error messages using miette.
  • Document all commands, flags, and options in code and in the CLI help output.
  • Write integration tests for CLI behavior and edge cases.
  • Ensure the CLI is robust against malformed input and unexpected usage.
  • Output should be clear and suitable for piping/automation.

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.
