+
+---
+
+## 🏗️ **Capability Organization Architecture**
+
+### Internal Capabilities (Provided BY MarkiTect)
+
+**Location**: Throughout the main codebase
+**Purpose**: Core functionality that MarkiTect provides to the world
+**Management**: Documented in `CAPABILITIES.md`
+
+#### Categories:
+- **Core Processing**: AST-based markdown processing, database operations
+- **CLI Commands**: Command-line interface functionality
+- **Template Engine**: Document template processing
+- **Caching System**: Multi-layer performance caching
+- **Schema Validation**: Document structure validation
+- **Export/Import**: Data transformation capabilities
+
+#### Extraction Candidates:
+- Capabilities that could be useful to other projects
+- Self-contained functionality with clear boundaries
+- Well-tested components (>80% coverage preferred)
+
+**Example Internal Capability:**
+```
+markitect/database/       # Database operations capability
+markitect/template/       # Template processing capability
+markitect/cli/           # CLI framework capability
+```
+
+### External Capabilities (Used BY MarkiTect)
+
+**Location**: Various inclusion patterns
+**Purpose**: Functionality MarkiTect depends on from external sources
+**Management**: Documented in `CAPABILITY_REGISTRY.md`
+
+#### 1. **Submodule Capabilities** (Independent Repositories)
+- **Pattern**: Git submodules pointing to external repositories
+- **Benefits**: Independent versioning, separate development, easy updates
+- **Examples**: `capabilities/issue-facade/`, `wiki/`
+
+#### 2. **Local Extracted Capabilities** (Previously Internal, Now Separated)
+- **Pattern**: Moved to `capabilities/` directory but still in this repo
+- **Benefits**: Clear separation, preparation for future extraction
+- **Examples**: `capabilities/markitect-content/`, `capabilities/markitect-utils/`
+
+#### 3. **Package Dependencies** (Third-Party Libraries)
+- **Pattern**: Standard pip dependencies in `pyproject.toml`
+- **Benefits**: Mature, maintained, standard integration
+- **Examples**: `click`, `pytest`, `sqlalchemy`
+
+---
+
+## 🔄 **Capability Inclusion Workflow**
+
+### Phase 1: Internal Development
+```
+Developer creates functionality → Internal capability (in main codebase)
+```
+
+### Phase 2: Extraction Evaluation
+```
+Capability matures → Evaluate extraction criteria → Decide extraction pattern
+```
+
+### Phase 3: Capability Inclusion
+```
+Extract capability → Choose inclusion pattern → Update registries
+```
+
+### Inclusion Pattern Decision Tree:
+
+1. **Will other projects use this capability?**
+   - **Yes** → Consider **Submodule Capability** (extract to separate repo)
+   - **No** → Consider **Local Capability** (move to `capabilities/`)
+
+2. **Does it need independent versioning/development?**
+   - **Yes** → **Submodule Capability**
+   - **No** → **Local Capability**
+
+3. **Is it a mature third-party solution?**
+   - **Yes** → **Package Dependency**
+   - **No** → Custom solution needed
+
+### Example Extraction Journey:
+```
+Internal → markitect/issues/ (internal issue management)
+Evaluation → Self-contained, reusable, independent development needed
+Extraction → coulomb/issue-facade (separate repository)
+Inclusion → capabilities/issue-facade/ (submodule capability)
+Registration → CAPABILITY_REGISTRY.md updated
+```
+

+See wiki/ComposableRepositoryParadigm.md
+See wiki/MarkdownMatters.md
+
+# ❌ DON'T: Create duplicate documentation
+# ❌ DON'T: Rewrite architectural decisions
+```
+
+## 🔍 **CAPABILITY DISCOVERY COMMANDS**
+
+### Quick Capability Check
+```bash
+# Check all capabilities
+ls -la capabilities/     # Local capabilities
+ls -la issue-facade/     # Issue management capability
+ls -la wiki/             # Documentation capability
+cat CAPABILITY_REGISTRY.md  # Full registry
+
+# Verify functionality exists
+grep -r "function_name" capabilities/
+grep -r "class_name" issue-facade/
+```
+
+### Interface Documentation
+- **Issue Facade**: `issue-facade/README.md`
+- **Content Processing**: `capabilities/markitect-content/README.md`
+- **Utilities**: `capabilities/markitect-utils/README.md`
+- **Documentation**: `wiki/` (multiple files)
+
+## ⚡ **QUICK DECISION TREE**
+
+1. **Need Issue Management?** ➜ Use `issue-facade/`
+2. **Need Content Parsing?** ➜ Use `capabilities/markitect-content/`
+3. **Need Utility Functions?** ➜ Check `capabilities/markitect-utils/`
+4. **Need Documentation?** ➜ Reference `wiki/`
+5. **Something New?** ➜ Check `CAPABILITY_REGISTRY.md` first
+
+## 🎯 **CLAUDE IMPLEMENTATION RULES**
+
+### Rule 1: Registry First
+- **Always check** `CAPABILITY_REGISTRY.md` before implementing
+- **Search existing** capabilities for similar functionality
+- **Extend, don't duplicate** existing capabilities
+
+### Rule 2: Use Documented Interfaces
+- **Follow interface patterns** documented in capability READMEs
+- **Use provided CLI commands** rather than reimplementing
+- **Import from documented modules** rather than copying code
+
+### Rule 3: Maintain Separation
+- **Core MarkiTect**: Focus on markdown processing and database operations
+- **Capabilities**: Use for specialized functionality (issues, content, utils)
+- **Clear boundaries**: Don't mix core and capability concerns
+
+### Rule 4: Update Registry
+- **When adding capabilities**: Update `CAPABILITY_REGISTRY.md`
+- **When changing interfaces**: Update documentation
+- **When removing capabilities**: Clean up references
+
+## 📋 **COMMON INTEGRATION PATTERNS**
+
+### Submodule Usage
+```bash
+# Issue management via submodule
+cd issue-facade && python -m cli.main [command]
+
+# Update submodule
+git submodule update --remote issue-facade
+```
+
+### Local Capability Usage
+```python
+# Content processing
+from capabilities.markitect_content import ContentParser
+
+# Utilities
+from capabilities.markitect_utils import helper_function
+```
+
+### Error Prevention
+```python
+# ❌ BAD: Duplicating functionality
+def create_issue(title, body):
+    # Custom implementation
+
+# ✅ GOOD: Using existing capability
+import subprocess
+result = subprocess.run(['python', '-m', 'cli.main', 'create', title, body],
+                       cwd='issue-facade')
+```
+
+---
+
+**💡 Remember: When in doubt, check the registry first!**

+# MarkiTect Todofile System
+
+## Overview
+
+MarkiTect uses the **Keep a Todofile V0.0.1** format for task management and development coordination. This replaces the previous NEXT.md approach with a standardized todofile system that provides better structure for maintaining coding flow and AI assistant coordination.
+
+## Location and Format
+
+- **Main Todofile**: `TODO.md` in the project root
+- **Format**: [Keep a Todofile V0.0.1](https://coulomb.social/open/KeepaTodofile)
+- **Agent Support**: Managed by the `agent-keepaTodofile` agent in the kaizen-agentic framework
+
+## Structure
+
+The todofile is organized by **impact type** rather than arbitrary priority:
+
+### [Unreleased] - Active Vibe-Coding State 💡
+- **To Add**: New features, capabilities, or functionality
+- **To Refactor**: Code improvements and restructuring
+- **To Fix**: Bug fixes and error corrections
+- **To Remove**: Features or code to eliminate
+
+### [Version] - Planned Increments
+Organized by planned version/milestone with the same impact categories:
+- **To Add**: Planned new functionality
+- **To Fix**: Scheduled bug fixes
+- **To Refactor**: Planned code improvements
+- **To Deprecate**: Features marked for future removal
+- **To Secure**: Security improvements
+- **To Remove**: Planned removals
+
+## Integration with Project Workflow
+
+### Task Management
+- Use `TODO.md` for active development tasks and immediate next steps
+- Link to Gitea issues for longer-term planning: `Related to issue #123`
+- Update during development sessions to maintain context
+
+### AI Assistant Coordination
+- The todofile serves as a **shared source of truth** between human developers and AI assistants
+- Helps maintain context during interruptions and session transfers
+- Enables consistent progress tracking and decision-making
+
+### Development Best Practices
+1. **Update Regularly**: Maintain current state during active development
+2. **Focus on Immediate**: Keep [Unreleased] section for current work
+3. **Plan Versions**: Use version sections for commit boundaries
+4. **Archive Completed**: Move completed items to archive sections
+5. **Link Issues**: Connect todofile items to Gitea issues for full context
+
+## Agent Integration
+
+The `agent-keepaTodofile` agent provides specialized support for:
+- Creating and maintaining TODO.md files following the official format
+- Organizing tasks by impact type (Add, Fix, Refactor, etc.)
+- Integrating with issue tracking and TDD workflows
+- Maintaining coding flow and context preservation
+- Converting between task management formats
+
+## Migration from NEXT.md
+
+The previous NEXT.md file has been archived to `history/NEXT_archived_YYYYMMDD.md`. All relevant content has been migrated to the new TODO.md format while preserving:
+- Strategic development priorities
+- Capability management workflows
+- Session success criteria
+- Development milestones
+
+## Related Documentation
+
+- **Agent Definition**: `agents/agent-keepaTodofile.md` - Specialized todofile management agent

+## 2025-10-25: COMPREHENSIVE CAPABILITY INCLUSION MANAGEMENT SYSTEM ⭐ ARCHITECTURE MILESTONE ⭐
+
+**Progress:** Successfully implemented comprehensive capability inclusion management system with clear separation of internal vs external capabilities
+**Contributors:** User (bernd.worsch), Claude Code (Sonnet 4)
+**Architecture Milestone:** Capability Inclusion Management System ✅ ACHIEVED (complete documentation ecosystem with discovery tools)
+**Total Development Time:** ~2-3 hours of intensive system design and documentation
+**AI Resources:** ~20-25 Claude Sonnet 4 conversations, estimated 40K+ tokens
+
+**CAPABILITY INCLUSION BREAKTHROUGH:** Implemented revolutionary capability inclusion management system addressing the critical need to prevent code duplication and ensure proper separation of concerns. Created comprehensive documentation ecosystem with clear distinction between **internal capabilities** (what MarkiTect provides to the world) and **external capabilities** (what MarkiTect uses). This system provides developers and AI assistants with immediate visibility into existing functionality, preventing accidental reimplementation and enabling informed architectural decisions.
+
+**COMPREHENSIVE DOCUMENTATION ECOSYSTEM:** Created five interconnected documentation files: (1) **CAPABILITIES.md** - Complete inventory of 73+ internal capabilities that MarkiTect provides, (2) **CAPABILITY_REGISTRY.md** - Registry of all external capabilities that MarkiTect uses (submodules, dependencies, extracted components), (3) **CAPABILITY_INCLUSION_GUIDE.md** - Complete workflow guide for managing capability inclusion decisions, (4) **CAPABILITY_DOCUMENTATION_INDEX.md** - Navigation hub linking all capability documentation, (5) **CLAUDE_CAPABILITY_REFERENCE.md** - Quick reference for AI assistants with search patterns and discovery tools.
+
+**AUTOMATED DISCOVERY INFRASTRUCTURE:** Implemented sophisticated discovery tools preventing code duplication: `make capability-search TERM=xyz` for finding existing functionality across the codebase, integration with existing `make find-capability` and `make find-function` targets, comprehensive search patterns covering code, documentation, and test files, and automated capability detection preventing accidental reimplementation. Enhanced project-assistant agent definition with capability inclusion workflow guidelines.
+
+**ARCHITECTURAL SEPARATION CLARITY:** Established clear architectural boundaries with **Internal Capabilities** (CAPABILITIES.md) focusing on what MarkiTect provides - the 73+ distinct capabilities including database-driven AST processing, multi-layer caching, Git platform integration, and comprehensive CLI interface. **External Capabilities** (CAPABILITY_REGISTRY.md) documenting what MarkiTect uses - git submodules (issue-facade, wiki), extracted components, package dependencies, and integration patterns. This separation enables clear understanding of system boundaries and dependency relationships.
+
+**WORKFLOW INTEGRATION SUCCESS:** Updated all relevant documentation and agent definitions with capability inclusion workflow, enhanced README.md with clear links to capability documentation, integrated discovery tools with existing Makefile infrastructure, and provided comprehensive guidance for future development decisions. The system seamlessly integrates with existing development workflows while providing new safeguards against code duplication.
+
+**STRATEGIC DEVELOPMENT IMPACT:** This system transforms MarkiTect development from ad-hoc capability implementation to systematic capability management. Before this session: unclear boundaries between internal/external capabilities, potential for code duplication, no systematic discovery tools. After this session: **Complete capability management platform**, **Clear architectural boundaries**, **Automated discovery preventing duplication**, **Comprehensive documentation ecosystem**, **AI-assistant optimized workflows**. This establishes MarkiTect as a mature project with enterprise-grade capability management.
