MABEAM TDD Implementation Plan for Foundation
Overview
This document outlines the Test-Driven Development (TDD) implementation of MABEAM (Multi-Agent BEAM) in the Foundation library. The implementation follows a phased approach with stability checkpoints at each step, ensuring no warnings, dialyzer passes, and credo –strict compliance before proceeding.
Implementation Philosophy
- TDD First: Every module starts with comprehensive tests
- Stability Checkpoints: Each step must pass all quality gates before proceeding
- Incremental Development: Small, focused changes that build upon each other
- Quality Gates: No warnings, dialyzer clean, credo –strict compliant, formatted
Quality Gates Checklist
Before each human review/commit checkpoint:
# 1. Format code
mix format
# 2. Check for warnings
mix compile --warnings-as-errors
# 3. Run dialyzer
mix dialyzer
# 4. Run strict credo
mix credo --strict
# 5. Run tests
mix test
# 6. Check test coverage
mix test --cover
Implementation Phases
Phase 1: Core Infrastructure (Foundation.MABEAM.Core)
Duration: 4-6 development cycles Goal: Establish the universal variable orchestrator with basic agent management
Phase 2: Agent Registry and Lifecycle (Foundation.MABEAM.AgentRegistry)
Duration: 3-4 development cycles
Goal: Implement robust agent lifecycle management with OTP supervision
Phase 3: Basic Coordination (Foundation.MABEAM.Coordination)
Duration: 4-5 development cycles Goal: Implement fundamental coordination protocols (consensus, negotiation)
Phase 4: Advanced Coordination (Foundation.MABEAM.Coordination.*)
Duration: 5-6 development cycles Goal: Implement sophisticated coordination strategies (auction, market-based)
Phase 5: Telemetry and Monitoring (Foundation.MABEAM.Telemetry)
Duration: 2-3 development cycles Goal: Comprehensive observability for multi-agent systems
Phase 6: Integration and Polish
Duration: 2-3 development cycles Goal: Final integration, documentation, and performance optimization
Human Review Points
Each step ends with a human review checkpoint where the developer:
- Verifies all quality gates pass
- Reviews code for architectural consistency
- Confirms tests provide adequate coverage
- Validates documentation is complete
- Commits the stable increment
