The Problem

AI agents suffer from Context Drift, Illusion of Completion, and Quality Degradation:

❌ Mark tasks DONE but leave empty pass statements
❌ Skip critical error handling
❌ Generate unstyled "developer art" UIs  
❌ Write superficial tests with no real assertions
❌ No accountability — human must review everything manually

The Solution

Verdict is a programmatic gatekeeper that sits between the AI agent and your codebase. Every task must pass all three gates before being marked complete:

<p align="center"> <code style="background: #1a1a2e; padding: 4px 12px; border-radius: 6px;">Agent Writes Code</code> <span style="color: #00f0ff; font-size: 20px;"> → </span> <code style="background: #1a1a2e; padding: 4px 12px; border-radius: 6px; border-left: 3px solid #00f0ff;">AST Audit</code> <span style="color: #00f0ff; font-size: 20px;"> → </span> <code style="background: #1a1a2e; padding: 4px 12px; border-radius: 6px; border-left: 3px solid #ff00ff;">UI Validation</code> <span style="color: #00f0ff; font-size: 20px;"> → </span> <code style="background: #1a1a2e; padding: 4px 12px; border-radius: 6px; border-left: 3px solid #00ff88;">95% Coverage + 80% Mutation</code> <span style="color: #00f0ff; font-size: 20px;"> → </span> <code style="background: #00ff88; color: #0a0a0f; padding: 4px 12px; border-radius: 6px; font-weight: bold;">✅ COMPLETED</code> </p>

Quick Start

1. Install

pip install verdict-mcp
# OR from source:
git clone https://github.com/Zubair-z/VERDICT-MCP.git
cd VERDICT-MCP
pip install -r requirements.txt

2. Scaffold a project

verdict init myproject
cd myproject

This creates: plan.md + auth_handler.py + db_handler.py + tests/test_auth_handler.py

3. Run as MCP Server (for AI agents)

python -m verdict_mcp

4. Run as REST API (for any HTTP client)

python -m verdict_mcp.api_server
# → http://localhost:8000
curl http://localhost:8000/health

5. Run full validation pipeline

curl -X POST http://localhost:8000/pipeline/run \
  -H "Content-Type: application/json" \
  -d '{
    "task_id": "TASK_001",
    "source_files": ["auth_handler.py"],
    "test_file": "tests/test_auth_handler.py",
    "target_file": "auth_handler.py",
    "ui_file": "main_window.py"
  }'
