+# Autonomous Work Reminder - TDD8 Implementation
+
+## 🎯 MISSION: Complete Issue #50 - Metaschema Definition
+
+**CRITICAL REMINDERS FOR AUTONOMOUS WORK:**
+
+### 📋 TDD8 Workflow - NEVER SKIP STEPS
+1. **ISSUE** - Understand requirements (Issue #50 already analyzed)
+2. **TEST** - Write failing tests first (RED state required)
+3. **RED** - Verify tests fail before implementation
+4. **GREEN** - Implement minimal code to pass tests
+5. **REFACTOR** - Clean up code while keeping tests green
+6. **DOCUMENT** - Update documentation and help
+7. **REFINE** - Polish and optimize
+8. **PUBLISH** - Commit and close issue
+
+### 🚨 AUTONOMOUS WORK PROTOCOLS
+
+#### DO NOT FORGET TO:
+- ✅ Run tests after each change to verify state
+- ✅ Commit frequently with descriptive messages
+- ✅ Update CLI help when adding new features
+- ✅ Maintain backward compatibility
+- ✅ Follow existing code patterns and conventions
+- ✅ Use proper PYTHONPATH=. for all test runs
+- ✅ Close the issue when complete using: `make close-issue NUM=50`
+
+#### QUALITY STANDARDS:
+- All tests must pass before moving to next TDD8 step
+- Code must follow existing project conventions
+- Documentation must be comprehensive
+- CLI integration must be complete and tested
+
+#### ISSUE #50 SPECIFIC REQUIREMENTS:
+- Define JSON Schema metaschema for MarkiTect extensions
+- Support heading text capture
+- Support content field instructions
+- Support outline structure representation

+
+#### COMPLETION CRITERIA:
+- Metaschema JSON file created and validated
+- Tests cover all metaschema features
+- Documentation explains structure and usage
+- CLI can validate schemas against metaschema
+- All existing schemas still validate correctly
+
+### 🔄 WORKFLOW COMMANDS
+```bash
+# Start work
+make tdd-start NUM=50
+
+# Run tests
+PYTHONPATH=. python3 -m pytest tests/ --tb=short -q
+
+# Commit work
+git add . && git commit -m "step: [TDD8_PHASE] description"
+
+# Close issue when complete

+# MarkiTect Schema Generation Capability Outline - GAMEPLAN
+
+## 🎯 Mission: Transform MarkiTect from Static Analysis to Dynamic Generation
+
+**Parent Issue**: [#46 - Schema generation capability outline](http://gitea.coulomb.social/coulomb/markitect_project/issues/46)
+
+**Vision**: Enable users to generate document variations from example documents through schema-driven templates with content instructions and data automation.
+
+---
+
+## 📋 Issue Breakdown & Implementation Order
+
+### **🏗️ Phase 1: Foundation (HIGH PRIORITY)**
+
+#### Issue #50: Define metaschema for JSON schema structure
+- **Priority**: High
+- **Status**: Ready to start
+- **Dependencies**: Current schema generation (Issue #5), JSON Schema validation (Issue #7)
+- **Goal**: Create JSON Schema specification that extends standard JSON Schema with MarkiTect-specific features
+- **Key Features**:
+  - Heading text capture support
+  - Content field instructions support
+  - Outline structure representation
+  - Backward compatibility with existing schemas
+- **Start Command**: `make tdd-start NUM=50`
+
+---
+
+### **🔧 Phase 2: Core Features (HIGH-MEDIUM PRIORITY)**
+
+#### Issue #51: Add outline mode to schema generation
+- **Priority**: High
+- **Dependencies**: Metaschema definition (Issue #50)
+- **Goal**: `markitect schema-generate --mode outline --depth 3 --outfile invoice.json example.md`
+- **Key Features**:
+  - New `--mode outline` option
+  - `--depth` parameter for control
+  - Schema title: "Schema from example.md" (not "for")
+  - Actual heading text capture
+
+#### Issue #52: Capture actual heading text in schemas
+- **Priority**: Medium
+- **Dependencies**: Metaschema (Issue #50), Current schema generation (Issue #5)
+- **Goal**: Preserve exact heading text in schemas for validation
+- **Key Features**:
+  - Store heading text alongside structure
+  - Enable heading text validation
+  - Meaningful error messages for mismatches
+
+---
+
+### **📝 Phase 3: Content Instructions (MEDIUM PRIORITY)**
+
+#### Issue #54: Add content field instruction capabilities
+- **Priority**: Medium
+- **Dependencies**: Metaschema (Issue #50), Heading text capture (Issue #52)
+- **Goal**: Include guidance for content authors in schemas
+- **Key Features**:
+  - Instructions for each section/content area
+  - Support for different content types
+  - Optional/required instruction flags
+  - CLI support for adding instructions
+
+---
+
+### **🚀 Phase 4: Generation Pipeline (MEDIUM PRIORITY)**
+
+#### Issue #55: Schema-based draft generation
+- **Priority**: Medium
+- **Dependencies**: All previous issues, Current stub generation (Issue #6)
+- **Goal**: Generate document templates from schemas with instructions
+- **Key Features**:
+  - New CLI command for draft generation
+  - Proper heading hierarchy from schema
+  - Content instruction placeholders
+  - Schema reference for future validation
+
+---
+
+### **🤖 Phase 5: Data Automation (LOW PRIORITY)**
+
+#### Issue #56: Data-driven multiple draft generation
+- **Priority**: Low
+- **Dependencies**: Schema-based draft generation (Issue #55)
+- **Goal**: Batch document generation from data sources
+- **Key Features**:
+  - Multiple data formats (JSON, CSV)
+  - Field mapping from data to schema
+  - Batch generation capabilities
+  - Data validation against schema
+
+---
+
+## 🛣️ Complete User Workflow (Target State)
+
+```bash
+# 1. Generate schema from example document
+markitect schema-generate --mode outline --depth 3 --outfile requirements_schema.json example_requirements.md
+
+# 2. Tune the schema (manual editing)
+# - Remove overly specific elements
+# - Add content instructions
+# - Refine outline structure
+
+# 3. Generate drafts from schema
+markitect generate-draft requirements_schema.json --outfile new_requirements.md
+
+# 4. Data-driven batch generation (future)
+markitect generate-batch requirements_schema.json --data projects.csv --output-dir ./generated/
+
+# 5. Validate generated documents
+markitect validate new_requirements.md requirements_schema.json
+```
+
+---
+
+## 🎯 Implementation Strategy
+
+### **Foundation-First Approach**
+1. **Start with Issue #50** - metaschema is prerequisite for everything
+2. **Parallel development** possible for Issues #51, #52 after #50
+3. **Sequential dependency** for Issues #54, #55, #56
+
+### **TDD Workflow Integration**
+- Use `make tdd-start NUM=X` for each issue
+- Write tests first, implement features second
+- Maintain backward compatibility throughout
+
+### **Testing Strategy**
+- Each issue requires comprehensive test coverage
+- Integration tests for end-to-end workflow
+- Performance testing for batch generation
+
+### **Documentation Requirements**
+- CLI help updates for new options
+- User guide for complete workflow
+- API documentation for new schema features
+
+---
+

+- ✅ Backward compatibility maintained
+- ✅ Validation rules implemented
+
+### **Phase 2 Success**: Outline Mode Working
