# Apply Footnotes

Read the `datascience:footnotes` skill first - it is the single source of truth for the footnote pattern. Do NOT duplicate its content here.

Add Jupyter-compatible footnotes to a notebook or markdown file. Converts inline references to superscript anchor links with a footnote section.

## What to do

1. Read the target file
2. Identify what needs footnotes based on user's request:
   - Paper references mentioned in prose
   - Technical claims that need sources
   - Acronyms or terms that need definition
   - Data sources that need attribution
   - User-specified items

Apply Footnotes

Read the datascience:footnotes skill first - it is the single source of truth for the footnote pattern. Do NOT duplicate its content here.

Add Jupyter-compatible footnotes to a notebook or markdown file. Converts inline references to superscript anchor links with a footnote section.

What to do

Read the target file
Identify what needs footnotes based on user's request:
- Paper references mentioned in prose
- Technical claims that need sources
- Acronyms or terms that need definition
- Data sources that need attribution
- User-specified items
For each footnote:
- Insert [N](#fnN) at the reference point in text
- Add N Footnote content.  to footnote section
If no footnote section exists, create one:
- In notebooks: add ## Footnotes markdown cell at the end, or --- separator in the same cell
- In markdown: add --- separator + footnotes at the bottom
Number footnotes sequentially: fn1, fn2, fn3...
- If file already has footnotes, continue from the highest existing number

Fixing existing footnotes

If the file has broken footnotes:

Missing id on spans -> add them
Mismatched numbers (sup says 3 but id says fn5) -> renumber
Plain [1] references -> convert to [1](#fn1) pattern
Footnotes without   between them -> add breaks
Standard markdown [^1] syntax (not supported in Jupyter) -> convert to anchor pattern
