# Dependency graph
requires:
  - phase: None
    provides: Initial project structure and dependencies
provides:
  - LM Studio client adapter for model discovery and inference
  - System resource monitoring for intelligent model selection
  - Model configuration system with resource requirements and fallback chains
affects: 01-model-interface (subsequent plans)

# Tech tracking

  modified: [".gitignore"]

key-decisions:
  - "Used context manager pattern for safe LM Studio client handling"
  - "Implemented graceful fallback for missing optional dependencies (gpu-tracker)"
  - "Created mock modules for testing without full dependency installation"
  - "Designed comprehensive model configuration with fallback chains"

patterns-established:
  - "Pattern 1: Model Client Factory - Centralized LM Studio client with automatic reconnection"
  - "Pattern 2: Resource-Aware Model Selection - Choose models based on current system resources"
  - "Configuration-driven architecture - Model definitions, requirements, and switching rules in YAML"
  - "Graceful degradation - Fallback chains for resource-constrained environments"

# Phase 1 Plan 1 Summary

**LM Studio connectivity and resource monitoring foundation with Python package structure**

## Performance

- **Duration:** 8 min
- **Started:** 2026-01-27T16:53:24Z
- **Completed:** 2026-01-27T17:01:23Z
- **Tasks:** 4
- **Files modified:** 8

## Accomplishments
- Created Python project structure with PEP 518 compliant pyproject.toml
- Implemented LM Studio adapter with model discovery and management capabilities
- Built comprehensive system resource monitoring with trend analysis
- Created model configuration system with fallback chains and selection rules

## Task Commits

Each task was committed atomically:

1. **Task 1: Create project foundation and dependencies** - `de6058f` (feat)
2. **Task 2: Implement LM Studio adapter and model discovery** - `f5ffb72` (feat)
3. **Task 3: Implement system resource monitoring** - `e6f072a` (feat)
4. **Task 4: Create model configuration system** - `446b9ba` (feat)

**Plan metadata:** completed successfully

## Files Created/Modified
- `pyproject.toml` - Python package metadata and dependencies
- `requirements.txt` - Fallback pip requirements
- `src/__init__.py` - Main package initialization
- `src/models/__init__.py` - Models module exports
- `src/models/lmstudio_adapter.py` - LM Studio client adapter
- `src/models/mock_lmstudio.py` - Mock for testing without dependencies
- `src/models/resource_monitor.py` - System resource monitoring
- `config/models.yaml` - Model definitions and configuration
- `.gitignore` - Fixed to allow src/models/ directory

## Decisions Made

- Used context manager pattern for safe LM Studio client handling to ensure proper cleanup
- Implemented graceful fallback for missing optional dependencies to maintain functionality
- Created comprehensive model configuration with resource requirements and fallback chains
- Followed research patterns: Model Client Factory and Resource-Aware Model Selection

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None - all verification tests passed successfully.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

Core infrastructure ready for model management:
- LM Studio client connects and discovers models (adapter works with fallback)
- System resources are monitored in real-time with trend analysis
- Model configuration defines resource requirements and fallback chains
- Foundation supports intelligent model switching for next phase

Ready for 01-02-PLAN.md: Conversation context management and memory system.
