- `agents-guide.md` - Comprehensive 12-agent reference (45 min read)
- `party-mode.md` - Multi-agent collaboration guide (20 min read)
- `scale-adaptive-system.md` - Deep dive on Levels 0-4 (42 min read)
- `brownfield-guide.md` - Existing codebase development (53 min read)
- `quick-spec-flow.md` - Rapid Level 0-1 development (26 min read)
- `workflows-analysis.md` - Phase 1 workflows (12 min read)
- `workflows-planning.md` - Phase 2 workflows (19 min read)
- `workflows-solutioning.md` - Phase 3 workflows (13 min read)
- `workflows-implementation.md` - Phase 4 workflows (33 min read)

- `troubleshooting.md` - Common issues and solutions

**Documentation Improvements:**
- Removed all version/date footers (git handles versioning)
- Agent customization docs now include full rebuild process
- Cross-referenced links between all guides
- Reading time estimates for all major docs
- Consistent professional formatting and structure

**Consolidated & Streamlined:**
- Module README (`src/modules/bmm/README.md`) streamlined to lean signpost
- Root README polished with better hierarchy and clear CTAs
- Moved docs from root `docs/` to module-specific locations
- Better separation of user docs vs. developer reference

## 🤖 New Agent: Paige (Documentation Guide)

**Role:** Technical documentation specialist and information architect

**Expertise:**
- Professional technical writing standards
- Documentation structure and organization
- Information architecture and navigation
- User-focused content design
- Style guide enforcement

**Status:** Work in progress - Paige will evolve as documentation needs grow

**Integration:**

- Available for all phases (documentation is continuous)
- Can be customized like all BMM agents

## 🔧 Additional Changes

- Updated agent manifest with Paige
- Updated workflow manifest with new documentation workflows
- Fixed workflow-to-agent mappings across all guides
- Improved root README with clearer Quick Start section
- Better module structure explanations
- Enhanced community links with Discord channel names

**Total Impact:**
- 18 new/restructured documentation files
