Constitutional Governance

ITDA enforces 9 Constitutional Articles for quality assurance:

# Validate constitutional compliance
itda-validate all
itda-validate constitution
itda-validate gates
itda-validate complexity

9 Articles:

1. Library-First Principle - All features begin as independent libraries
2. CLI Interface Mandate - All libraries expose CLI functionality
3. Test-First Imperative - Tests written before code (80% coverage required)
4. EARS Requirements Format - 5 EARS patterns for unambiguous requirements
5. Traceability Mandate - 100% traceability: Requirements ↔ Design ↔ Code ↔ Tests
6. Project Memory - Steering system maintains project context
7. Simplicity Gate - Maximum 3 sub-projects initially (Phase -1 Gate)
8. Anti-Abstraction Gate - Use framework APIs directly (Phase -1 Gate)
9. Integration-First Testing - Integration tests use real services (no mocks)

Phase -1 Gates: Pre-implementation validation checkpoints for Articles VII & VIII. See:

• steering/rules/constitution.md - Full constitutional text
• steering/rules/phase-gates.md - Approval process and active gates
• All other agents use Markdown format + AGENTS.md

Governance Articles

ITDA enforces 9 immutable constitutional articles:

1. Library-First Principle - Features start as libraries
2. CLI Interface Mandate - All libraries expose CLI
3. Test-First Imperative - Tests before code (Red-Green-Blue)
4. EARS Requirements Format - Unambiguous requirements
5. Traceability Mandate - 100% coverage required
6. Project Memory - All skills check steering first
7. Simplicity Gate - Maximum 3 projects initially
8. Anti-Abstraction Gate - Use framework features directly
9. Integration-First Testing - Real services over mocks

SDD Workflow (8 Stages)

1. Research → 2. Requirements → 3. Design → 4. Tasks →
5. Implementation → 6. Testing → 7. Deployment → 8. Monitoring

Each stage has:

• Dedicated skills
• Quality gates
• Traceability requirements
• Constitutional validation

EARS Requirements Format

### Requirement: User Login

WHEN user provides valid credentials,
THEN the system SHALL authenticate the user
AND the system SHALL create a session.

#### Scenario: Successful login

- WHEN user enters correct email and password
- THEN system SHALL verify credentials
- AND system SHALL redirect to dashboard

Bilingual Documentation

All agent-generated documents are created in both English and Korean.

Language Policy

• English: Reference/source documents (.md)
• Korean: Translations (.ko.md)
• Skills: Always read English versions for work
• Code References: Requirement IDs, technical terms stay in English

Files Generated Bilingually

Steering Context:

• steering/structure.md + steering/structure.ko.md
• steering/tech.md + steering/tech.ko.md
• steering/product.md + steering/product.ko.md

Specifications:

• storage/specs/auth-requirements.md + storage/specs/auth-requirements.ko.md
• storage/design/auth-design.md + storage/design/auth-design.ko.md
• storage/tasks/auth-tasks.md + storage/tasks/auth-tasks.ko.md

Generation Order

1. English version generated FIRST (reference/source)
2. Korean version generated SECOND (translation)
3. Technical terms (REQ-XXX-NNN, EARS keywords, API endpoints) remain in English
4. Both versions maintained in sync

Configuration

MCP Server Integration

ITDA v2.0.0 integrates with CodeGraphMCPServer for advanced code analysis.

Option 1: Claude Code (Terminal)

# Install CodeGraph MCP with pipx (--force ensures latest version)
pipx install --force codegraph-mcp-server

# Add to Claude Code
claude mcp add codegraph -- codegraph-mcp serve --repo .

# Verify installation
claude mcp list

Option 2: VS Code with Claude Extension

1. Install Prerequisites:

   # --force ensures latest version even if already installed
   pipx install --force codegraph-mcp-server

2. Configure VS Code (.vscode/mcp.json):

   {
     "servers": {
       "codegraph": {
         "type": "stdio",
         "command": "codegraph-mcp",
         "args": ["serve", "--repo", "${workspaceFolder}"]
       }
     }
   }

3. Or use Claude Desktop config (~/.claude/claude_desktop_config.json on macOS/Linux, %APPDATA%\Claude\claude_desktop_config.json on Windows):

   {
     "mcpServers": {
       "codegraph": {
         "command": "codegraph-mcp",
         "args": ["serve", "--repo", "/path/to/your/project"]
       }
     }
   }

Option 3: npx (No Installation)

# Add via npx (no global install needed)
claude mcp add codegraph -- npx -y @anthropic/codegraph-mcp --codebase .

Verify MCP Server is Working

After setup, test in Claude:

Use the init_graph tool to analyze this codebase

If successful, you'll see the code graph initialization output.

Available MCP Tools (14 tools):

Agent × MCP Tool Mapping:

Also integrates with other MCP servers:

• Context7 MCP - Up-to-date library documentation (Next.js, React, etc.)
• Azure MCP - Azure resource management
• Microsoft Learn MCP - Microsoft documentation

Skills automatically use available MCP servers when needed.

# Architecture patterns
steering/structure.md

# Technology stack
steering/tech.md

# Product context
