# Worker Task: Milestone 5 (memory_tools.py coverage)

## Goal
Improve test coverage and robustness of `reversecore_mcp/tools/common/memory_tools.py` to >= 75% (aiming for 100%).

## Context & Inputs
- Target source file: `reversecore_mcp/tools/common/memory_tools.py`
- Test file to modify: `tests/unit/tools/common/test_memory_tools.py`
- Pre-designed tests and patches from explorers:
  - `/Users/sjkim1127/Reversecore_MCP/.agents/explorer_m5_1/proposed_test_memory_tools.py`
  - `/Users/sjkim1127/Reversecore_MCP/.agents/explorer_m5_1/test_memory_tools.patch`
  - `/Users/sjkim1127/Reversecore_MCP/.agents/explorer_m5_2/analysis.md`
  - `/Users/sjkim1127/Reversecore_MCP/.agents/explorer_m5_3/analysis.md`

## Instructions
1. Replace or modify `tests/unit/tools/common/test_memory_tools.py` to incorporate the extended `mock_store` fixture and all the new test cases covering the 8 previously untested memory tools.
2. Run pytest on the modified test file:
   `pytest tests/unit/tools/common/test_memory_tools.py -v`
3. Verify test coverage is >= 75% for `reversecore_mcp/tools/common/memory_tools.py` using `pytest --cov=reversecore_mcp/tools/common/memory_tools --cov-report=term-missing tests/unit/tools/common/test_memory_tools.py`.
4. Run all existing tests to make sure no regressions are introduced.
5. Create a handoff.md in your working directory `.agents/worker_m5_1/` summarizing:
   - What changes were made
   - Verification commands and their output
   - Verified coverage metric for the target file
