The src/cleveragents/infrastructure/sandbox/checkpoint.py file has been identified as a violation of the Single Responsibility Principle.

Issues:

The file mixes several distinct concerns:

  1. Protocol: The Checkpointable protocol.
  2. Data Model: The SandboxCheckpoint model.
  3. Service Logic: The CheckpointManager class.

Recommendation:

Refactor the checkpoint.py file by splitting it into smaller, more focused modules:

  • Move the Checkpointable protocol to src/cleveragents/infrastructure/sandbox/protocol.py.
  • Move the SandboxCheckpoint model to a new models.py file within the sandbox package.
  • Keep the CheckpointManager class in src/cleveragents/infrastructure/sandbox/checkpoint.py.

This refactoring will improve the modularity, maintainability, and testability of the checkpoint functionality.

CLOSED: Consolidated into Epic #4179

This refactoring issue for checkpoint.py has been consolidated into Epic #4179: "Code Architecture Cleanup - Single Responsibility Principle Violations" along with all other Architecture Guard refactoring issues.

The checkpoint.py refactoring (Protocol + Model + Service separation) will be addressed in Phase 2 (v3.4.0) of the epic's implementation strategy as part of the "Infrastructure Files" category.

See Epic #4179 for consolidated implementation approach. Closing as duplicate/consolidated.
