Markdown Navigation

Overview

Provides a tool to quickly get the outline of section titles in a markdown file or extract the body of a specific section.

Core principle: Use simple bash script to parse markdown headers and content for efficient navigation.

When to Use

Need hierarchical outline of all sections in a markdown file
Need to extract content of a specific section without manual parsing
Working with large documentation files
When grep and read tools are insufficient for structured navigation
Symptoms: struggling to find sections in long markdown, manually scrolling through files, need focused reading of specific parts

Core Pattern

Use the markdown-viewer.sh script:

./markdown-viewer.sh file.md for outline
./markdown-viewer.sh file.md "Section Name" for section body

Quick Reference

Command	Description
`./markdown-viewer.sh file.md`	Print hierarchical outline of sections
`./markdown-viewer.sh file.md "Section"`	Print content of specified section

Implementation

The tool is implemented as a bash script located at markdown-viewer.sh in this skill directory.

It uses grep -E and sed to parse markdown headers and extract content ranges.

Common Mistakes

Section name must match exactly (case sensitive, includes spaces)
For outline mode, provide no second argument
Script requires executable permissions (chmod +x)
File path must be correct and accessible

Real-World Impact

Allows efficient navigation of large markdown files like documentation, changelogs, or project READMEs, saving time on manual searching and improving productivity when working with structured text.
