- Per skill
This is the reference set. A lot of third-party skills copy its shape: a SKILL.md with a name and a trigger description, then scripts and reference files the agent opens only when the task needs them.
The four document skills are the ones Claude uses to create and edit real Office files and PDFs. They ship under a proprietary license that allows use through Anthropic's services and forbids copying them out. The other fifteen are Apache 2.0, except doc-coauthoring, which states no license of its own.

- PDF Extract text and tables, merge and split files, fill forms, and OCR scanned pages.
- Word (DOCX) Create, read and edit Word documents, including tracked changes and comments.

- PowerPoint (PPTX) Create, edit and review slide decks, from templates to speaker notes.
