mq

Mq is an Agent Skill for documents published in the majiayu000/claude-skill-registry repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.

This skill should be used when the user asks to "get code blocks from README", "extract links from markdown", "find all headers in this doc", "pull the table from documentation", "what code examples are in this file", or when needing specific elements (code, links, headers, tables) from large Markdown files without loading the entire file.

QUICK START

How to use this skill

Bring this guide into your coding agent with a prompt tailored to the tool you use.

Open your project in Codex.
Copy and paste the prompt below.
Review files and risks before approving any action.

Prompt to paste

Inspect the Agent Skill at https://github.com/majiayu000/claude-skill-registry/blob/HEAD/skills/documents/mq/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/mq, but wait for my approval before writing files or running scripts.

Copying this prompt does not install or run the skill. Review third-party files before use.

mq: Markdown Query and Extraction Tool

Use mq to extract specific elements from Markdown files without loading entire file contents into context.

When to Use mq vs Read

Use mq when:

Need specific element(s) from Markdown file (headers, code blocks, links, tables)
File is large (>50 lines) and only need subset
Querying document structure
Extracting code samples, URLs, or table data
Saves 80-95% context vs reading entire file

Just use Read when:

File is small (<50 lines)
Need to understand overall structure
Making edits (need full context anyway)

Common File Types

Markdown files where mq excels:

README.md, CHANGELOG.md, documentation
GitHub wiki pages
Technical specifications
API documentation with code samples

Quick Examples

# Get all code blocks
mq '.code' README.md

# Get code blocks by language
mq '.code("rust")' file.md

# Get all links (URLs only)
mq '.link.url' file.md

# Get all headers
mq '.h' README.md

# Get level-2 headers only
mq '.h2' file.md

# Extract table data
mq '.[][]' file.md

Core Principle

Extract exactly what is needed in one command - massive context savings compared to reading entire Markdown files.
