Search the indexed knowledge base. Returns ranked source paths with line ranges, no content. Use rtfm_expand to read content.

How much of a project this index actually holds.

Say this before answering from the index when completeness matters: a partial index read as a complete one is how an absent result becomes "there is nothing on the subject".

The denominator is the scan's own list of files — not everything in the directory. Logs, lock files, state files and build output are not counted as gaps, because RTFM was never going to index them.

List indexed books with per-corpus summary and pagination.

Scan a project directory and return a structural map (file types, languages, entry points, size breakdown). ~1 second.

Get sources relevant to a subject. Returns paths + line ranges, no content. Use rtfm_expand to read.

Read content of an indexed file with line numbers.

Use after rtfm_search. Like Read, but for indexed files.

Show graph neighbors of a file (imports, links, includes, citations).

Show version history of an indexed file, or retrieve a specific version.

Each time a file is re-synced, its previous content is saved as a snapshot.
