# WHOOSH MVP Implementation Report

**Date:** September 4, 2025  
**Project:** WHOOSH - Autonomous AI Development Teams Architecture  
**Phase:** MVP Core Functionality Implementation  

---

## Executive Summary

This report documents the successful implementation of core MVP functionality for WHOOSH, the Autonomous AI Development Teams Architecture. The primary goal was to create the integration layer between WHOOSH UI, N8N workflow automation, and CHORUS AI agents, enabling users to add GITEA repositories for team composition analysis and tune agent configurations.

### Key Achievement
✅ **Successfully implemented the missing integration layer:** `WHOOSH UI → N8N workflows → LLM analysis → WHOOSH logic → CHORUS agents`

---

## What Has Been Completed

### 1. ✅ N8N Team Formation Analysis Workflow
**Location:** N8N Instance (ID: wkgvZU9oW0mMmKtX)  
**Endpoint:** `https://n8n.home.deepblack.cloud/webhook/team-formation`

**Implementation Details:**
- **Multi-step pipeline** for intelligent repository analysis
- **Webhook trigger** accepts repository URL and metadata
- **Automated file fetching** (package.json, go.mod, requirements.txt, Dockerfile, README.md)
- **LLM-powered analysis** using Ollama (llama3.1:8b) for tech stack detection
- **Structured team formation recommendations** with specific agent assignments
- **JSON output** compatible with WHOOSH backend processing

**Technical Architecture:**

        "model_recommendation": "llama3.1:8b"
      }
    ]
  }
}
```

### 2. ✅ WHOOSH Backend API Architecture
**Location:** `/home/tony/chorus/project-queues/active/WHOOSH/internal/server/server.go`

**New API Endpoints Implemented:**
- `GET /api/projects` - List all managed projects
- `POST /api/projects` - Add new GITEA repository for analysis
- `GET /api/projects/{id}` - Get specific project details
- `POST /api/projects/{id}/analyze` - Trigger N8N team formation analysis
- `DELETE /api/projects/{id}` - Remove project from management

**Integration Features:**
- **N8N Workflow Triggering:** Direct HTTP client integration with team formation workflow
- **JSON-based Communication:** Structured data exchange between WHOOSH and N8N
- **Error Handling:** Comprehensive error response for failed integrations
- **Timeout Management:** 60-second timeout for LLM analysis operations

### 3. ✅ Infrastructure Deployment

**Agent Information Tracked:**
```go
type Agent struct {
    ID             string    `json:"id"`             // Unique agent identifier
    Name           string    `json:"name"`           // Human-readable name
    Status         string    `json:"status"`         // online/idle/working
    Capabilities   []string  `json:"capabilities"`   // Available skills
    Model          string    `json:"model"`          // LLM model (llama3.1:8b)
    Endpoint       string    `json:"endpoint"`       // API endpoint

### Data Flow Architecture
1. **User Input:** Repository URL entered in WHOOSH UI
2. **API Call:** POST to `/api/projects` creates new project entry
3. **Workflow Trigger:** HTTP request to N8N webhook with repository data
4. **Repository Analysis:** N8N fetches files and analyzes technology stack
5. **LLM Processing:** Ollama generates team formation recommendations  
6. **Result Storage:** Analysis results stored in PostgreSQL database
7. **Agent Assignment:** CHORUS agents receive task assignments based on analysis
8. **Status Updates:** Real-time UI updates via WebSocket or polling

### Security Considerations
- **API Authentication:** JWT tokens for secure endpoint access
- **Secret Management:** Docker secrets for database passwords and API keys
