Markdown TOC

Use this skill when

Use this skill before editing a long Markdown file, especially when you need to:

• inspect the heading structure quickly;
• choose the best section for new content;
• avoid creating redundant sections; or
• review nearby lines before patching a note.

Quick start

Run the bundled script:

python3 {baseDir}/scripts/extract_toc.py /absolute/path/to/file.md

In this repository, common targets include:

python3 {baseDir}/scripts/extract_toc.py Notes/Gourmet.md
python3 {baseDir}/scripts/extract_toc.py Notes/AI-Agent-Product&PE.md

Workflow

1. Run the TOC script on the candidate file.
2. Read the returned heading tree and line numbers.
3. Open the most likely section neighborhood with sed -n '<start>,<end>p' or nl -ba.
4. Insert into an existing section when possible.
5. Create a new section only when the file truly lacks a clean landing spot.

Output format

The script prints a compact tree like this:

TOC
--------------------------------------------------
# Title (line 1)
  ## Section (line 20)
    ### Subsection (line 42)
