mq rust-crate.instructions.md

Coding rules for Rust crates in mq. A crate is a Rust package that groups related code and can be used as part of a larger project.

In plain words
What is it for?
Use them when creating or maintaining crates, public APIs, error types, optional features, dependencies, tests, or unsafe code.
Why use it?
They keep each package focused, documented, testable, and less exposed to accidental breakage.

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

mq rust-crate.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 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.

What it actually says

Rust Crate Coding Rules for mq

  • Each crate must have a clear purpose and be documented in its README.md (if present).
  • Organize code into logical modules; avoid large, monolithic files.
  • Use pub(crate) or tighter visibility unless wider exposure is necessary.
  • Prefer explicit error types using miette for user-facing errors.
  • Write comprehensive unit and integration tests in each crate.
  • Document all public APIs with Rust doc comments.
  • Avoid unsafe code unless absolutely necessary; document all unsafe blocks.
  • Use feature flags for optional functionality.
  • Keep dependencies minimal and up-to-date.
  • Each crate should have its own CHANGELOG.md if it is published independently.

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.
