Completed Phase 2 of the schema-of-schemas implementation with full markdown schema support. This enables schemas to be authored as markdown files with rich documentation and embedded JSON schemas. Core Implementation (markitect/schema_loader.py): - MarkdownSchemaLoader class with comprehensive parsing capabilities - YAML frontmatter extraction with error handling - JSON code block extraction with section preference (## Schema Definition) - Metadata merging with x-markitect-source tracking - Schema saving with template support and round-trip capability - Helper methods: list_json_blocks(), validate_schema_structure() Test Coverage (tests/test_schema_loader.py): - 35 comprehensive unit tests (100% passing) - Tests for loading, parsing, saving, round-trip conversion - Edge case handling (empty files, binary files, malformed blocks) - Fixed binary file test to use invalid UTF-8 sequences Example Schema (markitect/schemas/manpage-schema-v1.0.md): - First markdown schema following naming convention - Complete manpage schema with frontmatter + documentation + JSON - Demonstrates section classification and content control - Shows proper structure for future schema authors Documentation (roadmap/schema-of-schemas/SCHEMA_LOADER_GUIDE.md): - Comprehensive user guide (600+ lines) - API reference with examples - Best practices and troubleshooting - Integration patterns for CLI and validator Progress Tracking: - Updated TODO.md with Phase 2 completion - Updated CHANGELOG.md with implementation details - Next: Phase 3 - Schema-for-Schemas Metaschema 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

[Unreleased] - Active Vibe-Coding State 💡
This section is for tasks currently being discussed with or worked on by the coding assistant. These are the ephemeral, flow-of-thought tasks.
Schema-of-Schemas Implementation (Active - Phase 2)
Status: Phase 2 - Markdown Schema Loader (Completed ✅)
Workplan: See roadmap/schema-of-schemas/WORKPLAN.md
Current Goals:
- ✅ Establish naming convention:
{domain}-schema-v{major}.{minor}.md - ✅ Implement filename validation logic
- ✅ Create markdown schema loader
- ✅ Create example markdown schema
- ⏳ Build schema-for-schemas metaschema (Next: Phase 3)
- ⏳ Migrate existing schemas to new format
Phase 1 Tasks (Completed ✅):
- Write
markitect/schema_naming.pywith validation logic - Add unit tests for filename validation (50 tests, 100% passing)
- Create SCHEMA_NAMING_SPEC.md documentation
Phase 2 Tasks (Completed ✅):
- Implement MarkdownSchemaLoader class (markitect/schema_loader.py, 515 lines)
- Add frontmatter extraction (YAML)
- Add JSON code block extraction with section preference
- Add metadata merging with x-markitect-source tracking
- Write comprehensive unit tests (35 tests, 100% passing)
- Create example markdown schema (manpage-schema-v1.0.md)
- Create SCHEMA_LOADER_GUIDE.md documentation
Next Phases:
- Phase 3: Schema-for-Schemas Metaschema (2 days)
- Phase 4: Schema Migration (1-2 days)
- Phase 5: CLI & Documentation Updates (1 day)
- Phase 6: Testing & Validation (1 day)
Expected Completion: 6-7 days remaining
Extract Capability-Capability from Issue-Facade (Paused)
Context: Issue-facade currently provides two capabilities:
- issue-tracking (explicit in CAPABILITY-issue-tracking.yaml) - Issue management across platforms
- capability-capability (implicit) - Patterns and tools for creating/managing capabilities
The capability-capability includes:
- Feedback pattern (feedback/ directory, .capability/feedback CLI tool, documentation)
- Detachment facility (.capability/detach script for clean capability removal)
- Integration pattern (.capability/integrate.sh for project integration)
- CAPABILITY-*.yaml specification format
- ReusableCapabilitiesArchitecture.md (complete specification)
- Directory conventions (_family/implementation, visible/hidden patterns)
Goal: Extract capability-capability to separate reusable-capability repository so it can be used by any capability in the markitect ecosystem.
Approach: Step-by-step extraction, starting with specification.
Phase 1: Specification & Planning (Current)
- Create CAPABILITY-capability.yaml in issue-facade to explicitly declare the implicit capability
- Define what belongs to capability-capability family vs issue-tracking family
- Document the capability-capability API surface (what tools/patterns it provides)
- Identify all files/directories to extract
- Plan extraction strategy (copy vs move, how to maintain during transition)
Phase 2: Repository Creation
- Create reusable-capability repository structure
- Extract ReusableCapabilitiesArchitecture.md to new repo
- Extract feedback pattern (directory structure, CLI tool, README)
- Extract detachment facility (.capability/detach)
- Extract integration scripts (.capability/integrate.sh, integration-checklist.md)
- Create CAPABILITY-capability.yaml in new repo (canonical version)
- Add README.md for reusable-capability repo
Phase 3: Integration & Testing
- Update issue-facade to depend on reusable-capability (as integrated capability)
- Integrate reusable-capability into issue-facade using _capability/reusable-capability pattern
- Test that issue-facade still works with extracted capability
- Update issue-facade documentation to reference both capabilities it provides/uses
- Verify feedback system still works
- Verify detachment still works
Phase 4: Dogfooding & Validation
- Choose another markitect capability for dogfooding
- Integrate reusable-capability into that capability
- Add feedback system to new capability
- Add detachment facility to new capability
- Document learnings and refine reusable-capability based on real-world usage
- Update ReusableCapabilitiesArchitecture.md with insights
Current Step: Phase 1, Task 1 - Create CAPABILITY-capability.yaml
Completed Tasks
Recent completed tasks have been documented in _issue-tracking/issue-facade/CHANGELOG.md following Keep a Changelog format.
