## When to use
Prepare any document for retrieval without ever filling the context window.

## Operations
- chunk by page
- chunk by max chars w/ overlap
- persist chunks + page text
- only the needed chunks are ever passed to the model

## Engine (what actually executes this)
`universal_pdf/core.chunk:chunk_document / chunk_text`

All heavy lifting is done on disk / one page at a time by the shared engine —
never by loading the document into an LLM context.

## Tools & graceful degradation
- Preferred tool: **local chunker (page & word boundaries)**
- Fallback: **—**

If the preferred backend is unavailable the skill transparently uses the
fallback or reports a documented limitation. It **never** reports success when
an operation did not actually happen.

## Validation (this skill attaches checks to its Outcome)
chunks>=1
