mq is a command-line tool for querying and transforming Markdown with syntax modeled on jq, a utility commonly used for processing JSON. It helps developers extract sections, reshape documentation, analyze content, and prepare Markdown for language-model workflows. Its catalogue add-ons support using mq through coding-agent instructions and skills.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00011 | $0.00177 |
| Opus 5 | $0.00005 | $0.00088 |
| Sonnet 5 | $0.00002 | $0.00035 |
| Haiku 4.5 | $0.00001 | $0.00018 |
Grade A, and why
code-review 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 today.
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
Code Review (for Copilot)
Performs a comprehensive code review for the mq project, focusing on quality, performance, and adherence to project conventions.
Usage
- If arguments are provided, review only the specified files or directories
- If no arguments, review the entire codebase
- Supports glob patterns and multiple paths
What it does
- Analyzes Rust code for performance and optimization
- Reviews code for mq conventions and best practices
- Checks error handling with miette
- Validates documentation for public APIs
- Identifies security issues and anti-patterns
- Suggests improvements for maintainability and readability
Example
/code-review crates/mq-lang/src/ /code-review src/lexer.rs src/parser.rs /code-review "crates//src/.rs"
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.

code-review is a command published in the GitHub repository harehare/mq (1,027 stars, last pushed today), licensed MIT. It adds 11 tokens to every session and 177 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings.
