CLEAN BREAK ARCHITECTURE IMPLEMENTATION

We are implementing a clean break architecture approach that prioritizes architectural clarity, consistent patterns, and future extensibility. This involves a phased redesign of core components around services, breaking backward compatibility when necessary. We will implement service-enabled versions of providers, agents, and knowledge systems that work alongside existing implementations until we’ve validated the new architecture.

Current Sprint Focus

Revised Priority Requirements

1. Core Services Integration (Critical) ✅

   • Core service interfaces and schemas implemented
   • Service registry implementation completed
   • Event system with middleware functionality working
   • Buffer system with flow control implemented
   • State container with transitions operational
   • Command pattern system fully implemented
   • Fixed all implementation issues and tests passing

2. Provider System Redesign (Critical)

   • Complete base provider with service integration
   • Implement provider command pattern
   • Create service-enabled implementations for all providers

3. Schema-Validated Interfaces (Critical)

   • Ensure all components have schema validation
   • Validate all inter-component communication
   • Create comprehensive validation test suite

Development Tools Best Practices

With enhanced pyproject.toml configuration, we now have simplified developer commands:

# Testing with pytest (includes coverage automatically)
uv run pytest                              # Run all tests with coverage
uv run pytest atlas/tests/core/services/  # Run specific test modules with coverage

# Code quality tools
uv run mypy atlas                         # Type check the project
uv run ruff check .                       # Lint the project
uv run ruff format .                      # Format the project

# Pre-commit hooks
uv run pre-commit run --all-files         # Run all pre-commit hooks

The project configuration has been optimized so that uv run pytest automatically includes coverage reporting with the right settings, and all tools can be run directly without the python -m prefix.
