🤖 Multi-AI Collaboration

NEW: This project demonstrates advanced AI collaboration using complementary strengths:

• GitHub Copilot: Strategic planning, architecture design, integration oversight
• Google Gemini: Implementation details, coding, template development
• Coordination Framework: `ai-collaboration/` folder with handoff protocols
• Status Tracking: Real-time collaboration logs and decision tracking

See `ai-collaboration/README.md` for complete collaboration protocols.

🧠 BREAKTHROUGH: Enhanced AI Turnover Protocol

🚀 INNOVATION: Solves the "AI session discontinuity problem" - enables seamless cognitive transfer between chat sessions for complex projects.

Revolutionary Features:

• 🔮 Cognitive DNA Transfer: Mental models, intuitive insights, invisible decisions
• 🎭 Personality Continuation: Maintains collaboration style across sessions
• ⚡ Energy Mapping: Tracks momentum vs friction in codebase
• 📊 Code Health Dashboard: Visual technical metrics
• 🤖 Multi-AI Coordination: Explicit handoff protocols

Usage:

# Use enhanced turnover templates in ai-collaboration/
ENHANCED_TURNOVER_TEMPLATE.md    # Revolutionary template design
FILLED_TURNOVER_PROMPT.md        # Complete project context
COPY_PASTE_NEW_SESSION.md        # Ready-to-use session starters

Result: New AI sessions feel like natural continuations rather than starting from scratch!

🔧 Modular Tool Registry

NEW: Scalable tool management system:

• Version-Aware: Multiple tool versions with automatic selection
• A/B Testing: Built-in support for feature flags and testing
• Type-Safe: Full TypeScript support with ContractResult
• Legacy Support: Seamless integration with existing tools
• Hot Registration: Dynamic tool loading and unloading

Overview

The SDD MCP Server automates the proven Seam-Driven Development workflow:

1. Requirements Analysis → Identify component seams

2. Contract Generation → Define interfaces using ContractResult patterns

3. Stub Creation → Generate implementation templates with blueprint comments

4. Integration Testing → Validate seam connections

5. Implementation → Build components with clear contracts

This prevents the "70% wall" problem in AI-assisted development by defining component connections (contracts) before building implementations.

Features

Core SDD Functions

• `sdd_analyze_requirements` - Analyze PRD text and identify all component seams
• `sdd_generate_contract` - Generate contracts with proven SDD patterns
• `sdd_create_stub` - Create implementation stubs with blueprint comments
• `sdd_orchestrate_full_workflow` - Complete automation from PRD to ready-for-implementation

SDD Patterns

• ContractResult for type-safe data flow
• Blueprint comments for implementation guidance
• AgentId tracking for component identification
• Health check methods for system validation
• NotImplementedError patterns for stub creation

Installation

npm install
npm run build

Usage

As MCP Server

1. Configure in Claude Desktop's MCP settings:

{
  "mcpServers": {
    "sdd-server": {
      "command": "node",
      "args": ["path/to/sdd-mcp-server/dist/index.js"]
    }
  }
}

2. Use SDD functions in AI conversations:

Direct Usage

# Test the server
npm start

# Development mode
npm run dev

Example Workflow

// 1. Analyze requirements
const seams = await sdd_analyze_requirements({
  prdText: "Build a task management system...",
});

// 2. Generate contracts
const contract = await sdd_generate_contract({
  seam: {
    name: "UserAgent_TaskStore",
    participants: ["UserAgent", "TaskStore"],
    dataFlow: "BOTH",
    purpose: "User task CRUD operations",
  },
});

// 3. Create implementation stubs
const stub = await sdd_create_stub({
  contractCode: contract.contractCode,
  componentName: "TaskStore",
});

// 4. Full workflow automation
const project = await sdd_orchestrate_full_workflow({
  prdText: "Build a task management system...",
  projectName: "TaskManager",
});

SDD Methodology

Seam-Driven Development is a proven methodology for AI-assisted software development that:

1. Identifies Seams First - Find component boundaries before implementation

2. Defines Contracts - Create clear interfaces using type-safe patterns

3. Generates Stubs - Build implementation templates with guidance

4. Validates Integration - Test component connections early

5. Implements Components - Build with clear contracts and expectations

This approach prevents the common "70% wall" where AI-generated code becomes unwieldy and hard to integrate.
