Project Documenter

Generates a three-layer, AI-native documentation hierarchy for any software repository.

Layer 1  DOC_INDEX.md    — compressed routing layer (~1–2k tokens)
Layer 2  CLAUDE.md       — engineering navigation map (150–300 lines)
Layer 3  /docs/**        — authoritative domain sub-documents (all detail here)

Core law: Sub-documents hold all detail. CLAUDE.md routes to sub-docs. DOC_INDEX.md routes to CLAUDE.md. Nothing is ever duplicated across layers. Both CLAUDE.md and DOC_INDEX.md are generated LAST, synthesized from what was actually written.
