# BRIEFING — 2026-06-26T17:40:00Z

## Mission
Analyze how to extend the `mock_store` fixture in `tests/unit/tools/common/test_memory_tools.py` to support testing all 11 memory tools.

## 🔒 My Identity

- Milestone: m5

## 🔒 Key Constraints
- Read-only investigation — do NOT implement
- Operating in CODE_ONLY network mode: No external internet access, no downloading/uploading.
- Write only to own folder /Users/sjkim1127/Reversecore_MCP/.agents/explorer_m5_3/

## Investigation State
- **Explored paths**:
  - `tests/unit/tools/common/test_memory_tools.py` (Test suite structure, current `mock_store` fixture, current registration tests)
  - `reversecore_mcp/tools/common/memory_tools.py` (Implementation of the 11 MCP memory tools)
  - `reversecore_mcp/core/memory.py` (Implementation of the `MemoryStore` interface and database operations)
- **Key findings**:
  - Identified all 12 memory store methods (including `initialize`) called across the 11 memory tools, with their precise signatures and expected return types.
  - Identified that 8 of the 11 memory tools currently have no unit tests, leading to 51% coverage on `memory_tools.py`.
  - Identified a critical bug in the current `mock_store` fixture's `get_session` method return value (lacked the `"id"` key, which would cause `KeyError: 'id'` if used in `resume_memory_session`).
  - Identified that `TestRegisterMemoryTools.test_registration` only asserts `mcp.tool.call_count == 11` which is brittle; recommended asserting actual registered tool names by moving the `mock_mcp` fixture to module level.
- **Unexplored areas**:
  - None. Full coverage of all requested scope.

## Key Decisions Made
- Outlined a fully functional extended `mock_store` fixture.
- Proposed concrete code and design improvements for `TestRegisterMemoryTools`.
