Accomplishments

• Created comprehensive conversation data models with Pydantic validation

• Established adaptive context windows for different model sizes

Task Commits

Each task was committed atomically:

1. Task 1: Create conversation data structures - 221717d (feat)
2. Task 2: Implement context manager with compression - ef2eba2 (feat)

Plan metadata: N/A (docs only)

Files Created/Modified

• src/models/conversation.py - Data models for messages, conversations, and context windows with validation
• src/models/context_manager.py - Context management with intelligent compression and token budgeting

Decisions Made

• Used Pydantic models over dataclasses for automatic validation and serialization
• Implemented rule-based compression strategy instead of LLM-based for v1 simplicity
• Fixed compression threshold at 70% per CONTEXT.md requirements
• Added message importance scoring for selective retention during compression
• Created adaptive context windows to support different model sizes

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

User Setup Required

None - no external service configuration required.

Next Phase Readiness

Conversation management foundation is ready:

• Message storage and retrieval working correctly
• Context compression triggers at 70% threshold preserving important information
• System supports adaptive context windows for different models
• Ready for integration with model switching logic in next plan

All verification tests passed:

• ✓ Messages can be added and retrieved correctly
• ✓ Context compression triggers at correct thresholds
• ✓ Important messages are preserved during compression
• ✓ Token estimation works reasonably well
• ✓ Context adapts to different model window sizes
