MABEAM TDD IMPLEMENTATION

Documentation for MABEAM_TDD_IMPLEMENTATION from the Foundation repository.

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:

  1. Verifies all quality gates pass
  2. Reviews code for architectural consistency
  3. Confirms tests provide adequate coverage
  4. Validates documentation is complete
  5. Commits the stable increment

Next Steps

  1. Start with Phase 1: Begin with MABEAM_PHASE_01_CORE.md
  2. Follow TDD Cycle: Red → Green → Refactor for each step
  3. Maintain Quality: Ensure all quality gates pass at each checkpoint
  4. Human Review: Stop at each checkpoint for review and commit
  5. Document Progress: Update this file with completion status
