- `quick-start.md` - 15-minute getting started guide
- `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)
- `workflows-testing.md` - Testing & QA workflows (29 min read)
- `workflow-architecture-reference.md` - Architecture workflow deep-dive
- `workflow-document-project-reference.md` - Document-project workflow reference
- `enterprise-agentic-development.md` - Team collaboration patterns
- `faq.md` - Comprehensive Q&A covering all topics
- `glossary.md` - Complete terminology reference
- `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

+# Design Thinking Workflow
+
+**Type:** Interactive Document Workflow
+**Module:** Creative Intelligence System (CIS)
+
+## Purpose
+
+Guides human-centered design processes through the complete design thinking methodology: Empathize, Define, Ideate, Prototype, and Test. Creates solutions deeply rooted in user needs by combining empathy-driven research with systematic creative problem-solving.
+
+## Distinctive Features
+
+- **Phase-Based Structure**: Full five-phase design thinking journey from empathy to testing
+- **Method Library**: Curated collection of design methods in `design-methods.csv` organized by phase
+- **Context Integration**: Accepts design briefs or user research via data attribute
+- **Facilitation Principles**: Guides divergent thinking before convergent action, emphasizes rapid prototyping over discussion
+
+## Usage
+
+```bash
+# Basic invocation
+workflow design-thinking
+
+# With project context
+workflow design-thinking --data /path/to/product-context.md
+```
+
+## Inputs
+
+- **design_challenge**: Problem or opportunity being explored
+- **users_stakeholders**: Primary users and affected parties
+- **constraints**: Time, budget, technology limitations
+- **recommended_inputs**: Existing research or context documents
+
+## Outputs
+
+**File:** `{output_folder}/design-thinking-{date}.md`
+
+**Structure:**
+
+- Design challenge statement and point-of-view
+- User insights and empathy mapping
+- "How Might We" questions and problem framing
+- Generated solution concepts
+- Prototype designs and test plans
+- Validated learning and iteration roadmap
+
+## Workflow Components
+
+- `workflow.yaml` - Configuration with design_methods CSV reference
+- `instructions.md` - 7-step facilitation guide through design thinking phases
+- `template.md` - Structured output format
+- `design-methods.csv` - Phase-specific design techniques library
