mq markdown.instructions.md

A set of coding rules for `mq-markdown`, the part of a jq-like command-line language that parses and transforms Markdown. Markdown is plain text with conventions for headings, links, lists, and other formatting.

In plain words
What is it for?
Use it when adding or changing Markdown parsing, transformation, public API documentation, tests, or malformed-input handling.
Why use it?
It keeps Markdown logic in one place, requires tests and documentation, and ensures malformed input produces useful errors instead of crashes.

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 markdown.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

Markdown Parser/Utility Coding Rules

  • All Markdown parsing and manipulation logic must reside in mq-markdown.
  • Write tests for all parsing and transformation functions.
  • Ensure robust handling of edge cases in Markdown syntax.
  • Document all public APIs and provide usage examples in doc comments.
  • Avoid panics on malformed input; return descriptive errors using miette.
  • Keep the API surface minimal and focused on Markdown processing.
Changes

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.
