read_file's auto-extraction covered only the stdlib trio (.ipynb/.docx/
.xlsx). firecrawl-anydoc (MIT, Rust core, imports as `anydoc`) converts
Word, PowerPoint, Excel — including legacy .doc/.ppt/.xls — OpenDocument,
RTF, EPUB, and PDF to clean Markdown through one shared document model.
Wiring follows the footprint ladder: no new tool, no hard dependency.
- tools/read_extract.py gains an ANYDOC_EXTENSIONS set that is active
only when the converter imports; the stdlib extractors remain
authoritative for their three formats so behavior is identical with
or without the package.
- tools/lazy_deps.py adds tool.doc_extract (firecrawl-anydoc==0.1.6),
installed on first read of such a file with prompt=False so read_file
can never block. Lazy-only for now: the package's first release was
2026-08-04, inside uv's 14-day exclude-newer quarantine, so the
mirrored pyproject extra lands after it clears.
- Any anydoc ConvertError maps to ExtractionError, falling back to the
existing path/binary handling instead of erroring the tool.
Tests: real-binding suite skips cleanly when the wheel is absent
(verified: 15 passed/3 skipped without it, 18 passed with it), plus an
absent-dep contract class that pins the fallback regardless of local
install state.
