# PDMT Integration Specification v1.0

**Document Type**: Technical Specification  
**Version**: 1.0.0  
**Status**: DRAFT  
**Created**: 2025-08-13  
**Author**: Noah Gift  
**Target**: PAIML MCP Agent Toolkit Integration with PDMT (Pragmatic Deterministic MCP Templating)

## Executive Summary

This specification defines the integration of PDMT (Pragmatic Deterministic MCP Templating) with the PAIML MCP Agent Toolkit to create an enterprise-grade, deterministic todo generation system with comprehensive quality enforcement. The integration leverages PAIML's existing quality-gate proxy infrastructure to ensure all AI-generated code meets strict quality standards before reaching production systems.

## Problem Statement

Current AI-assisted development suffers from:

1. **Non-deterministic outputs** - Same requirements produce different todo structures
2. **Inconsistent quality** - No standardized validation for AI-generated todos
3. **Missing quality gates** - Code generation bypasses established quality controls
4. **Fragmented tooling** - Todo generation, validation, and quality enforcement exist separately
5. **Safety concerns** - AI-generated code reaches filesystems without proper validation

## Solution Architecture

### Core Integration Pattern

```
AI Request → PAIML MCP Server → PDMT Engine → Quality Gate Proxy → Safe Code Generation
                                      ↓
                            Quality Enforcement Pipeline
                                      ↓
                    [Coverage] [Doctests] [Property Tests] [Examples] [SATD Detection]
```

### Key Components

1. **PDMT MCP Tool Integration**: Native MCP tools for deterministic todo generation
2. **Quality Gate Enforcement**: Mandatory quality validation for all generated code
3. **Proxy Mode Safety**: All code generation routed through PAIML quality proxy
4. **Deterministic Templates**: 0.0 temperature templating for reproducible outputs
5. **Comprehensive Validation**: Multi-layered quality checks before code acceptance

## Quality Standards

### Mandatory Requirements

1. **100% Deterministic**: Same inputs must produce identical outputs
2. **80% Coverage Minimum**: All code must meet coverage thresholds  
3. **Zero SATD Tolerance**: No TODO/FIXME/HACK comments allowed
4. **Doctest Required**: All public APIs must have working examples
5. **Property Test Coverage**: Complex logic requires property validation
6. **Example Validation**: All examples must execute successfully
7. **Proxy Validation**: All code must pass PAIML quality proxy
8. **Complexity Limits**: Maximum cyclomatic complexity of 8 per function

### Success Metrics

- **Quality Gate Pass Rate**: 100% (zero tolerance for failures)
- **Response Time**: <1 second for typical todo generation
- **Determinism**: 100% identical outputs for identical inputs  
- **Coverage**: >80% for all generated code
- **Example Success**: 100% of examples execute without errors
- **SATD Detection**: 100% detection rate for prohibited comments

## Security Considerations

1. **Sandbox Execution**: All generated code runs in isolated environments
2. **Input Validation**: Comprehensive validation of all user inputs
3. **Output Sanitization**: Generated code sanitized before filesystem access
4. **Proxy Validation**: Mandatory quality proxy approval before code acceptance
5. **Audit Logging**: Complete audit trail of all quality gate decisions
6. **Rollback Capability**: Ability to revert any generated code that passes initial gates but fails later

## Risk Mitigation

### High-Risk Areas
- **Quality Gate Bypass**: Strict enforcement prevents any bypass mechanisms
- **Determinism Failure**: Property tests validate reproducible outputs
- **Performance Degradation**: Benchmarking prevents performance regressions
- **Security Vulnerabilities**: Comprehensive input validation and output sanitization

### Mitigation Strategies
- **Defense in Depth**: Multiple quality gate layers
- **Automated Testing**: Comprehensive test coverage at all levels  
- **Continuous Monitoring**: Quality metrics tracked and alerted
- **Rollback Procedures**: Quick reversion for any issues

## Future Enhancements

1. **ML-Powered Quality Prediction**: Predict quality issues before generation
2. **Advanced Complexity Analysis**: Semantic complexity beyond cyclomatic
3. **Custom Quality Rules**: User-defined quality standards
4. **Performance Profiling Integration**: Automatic performance validation
5. **Security Scanning Integration**: Vulnerability detection in generated code

## Conclusion

This specification defines a comprehensive integration between PDMT and PAIML MCP Agent Toolkit that ensures enterprise-grade, deterministic todo generation with comprehensive quality enforcement. The integration leverages existing PAIML quality infrastructure while adding deterministic templating capabilities to create a robust, safe, and reliable system for AI-assisted development.

The phased implementation approach ensures incremental delivery of value while maintaining strict quality standards throughout the development process. The mandatory quality gates provide multiple layers of protection against low-quality or unsafe code generation, ensuring that all outputs meet enterprise standards before reaching production systems.
