# Challenger Task: Milestone 5 (memory_tools.py coverage) Challenger 2

## Goal
Independent empirical verification of correctness, error pathways, and exception handling of the memory tools tools.

## Context & Inputs
- Target source file: `reversecore_mcp/tools/common/memory_tools.py`
- Test file modified: `tests/unit/tools/common/test_memory_tools.py`

## Instructions
1. Independently evaluate the updated test cases.
2. Verify if the tests adequately check for incorrect/unusual mock behavior (e.g. empty results from searches, DB operational exceptions, invalid query strings).
3. Confirm that the implementation under test maintains interface contracts.
4. Write your findings and confirmation in `handoff.md` inside your working directory `.agents/challenger_m5_2/`.
