pdf2epub-calibration SKILL.md skillA
pdf2epub-calibration from moonlight-lupin/agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add moonlight-lupin/agent-skills/pdf2epub-calibration@v1.2.1Pins v1.2.1 in mdr.lock. Pin the fingerprint instead.

Use when a converted PDF→EPUB misclassifies lines or covers, e.g. 'footnote links broken', 'page numbers became endnotes', 'cover came out as texture fragment', 'chapter headings resolve to wrong pages', 'endnote links dangle'. Calibration threshold rules for the pdf2epub pipeline: folio/fnref/footnote classification, endnote-section books, caption handling, front-matter language.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# PDF→EPUB Classifier Calibration
## When to Use
- A converted EPUB has citations in body text, page numbers as phantom endnotes, or broken/duplicate footnote links
- Chapter headings resolve to wrong PDF pages
- The cover image comes out as a texture fragment or a naked photo without typography
## Span-merge reality (check the dump, not the flag)
- `page.get_text("dict")` gives lines whose spans merge text at different font sizes. A body line can contain a 5pt footnote-ref span inside 12pt text — text extraction sees ONE line at the max span size.
- Superscript flags are unreliable: several authoring tools (QuarkXPress-style CJK exports included) emit footnote refs as STANDALONE 6pt lines with the sup flag UNSET, and emit the note's own number as a leading 5pt span merged into the note's first line. Gate ref detection on size + position, never on the sup flag alone.
- Before changing any threshold, dump per-page lines with text/size/flags/y-ratio. Most classification misses are span-merge artifacts, not wrong thresholds.

How to install
mdr add moonlight-lupin/agent-skills/pdf2epub-calibration@sha256:2e10c6e202d54269The line at the top of this page pins the label v1.2.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
