Find sections that have no content

Goal: Spot placeholder or empty sections, headings with nothing written under them yet, as a quick doc-completeness check.

Prerequisites: The section module, via -A or nodes.

Query

$ mq -A 'section::sections | filter(fn(s): !section::has_body(s);) | section::titles' README.md

Input

# Introduction

Welcome to the project.

## Empty Section

## Usage

Use the tool like this.

Output

Empty Section

Notes

• Flip the predicate (drop the !) to list sections with content instead, e.g. as a sanity check that nothing got filtered out by mistake.
• “No content” means no non-heading nodes directly under it. A subsection’s own text doesn’t count as its parent’s content: a heading followed only by a deeper heading (# Parent then ## Child with text under Child) still flags Parent as empty.
