# BRIEFING — 2026-06-27T02:40:00+09:00

## Mission
Analyze 8 memory tools in reversecore_mcp/tools/common/memory_tools.py and tests/unit/tools/common/test_memory_tools.py for edge cases, boundary conditions, and negative test scenarios.

## 🔒 My Identity
- Archetype: explorer
- Roles: read-only explorer
- Working directory: /Users/sjkim1127/Reversecore_MCP/.agents/explorer_m5_2
- Original parent: 81bd3cc5-8a01-423b-b2bd-0fbfba74c6e7
- Milestone: memory_tools_analysis

## 🔒 Key Constraints
- Read-only investigation — do NOT implement
- Focus on error handling (missing sessions, initialization failures, empty search results, invalid parameters)
- Detail mock configuration and assertions needed for these error conditions

## Investigation State
- **Explored paths**:
  - `reversecore_mcp/tools/common/memory_tools.py`
  - `tests/unit/tools/common/test_memory_tools.py`
  - `reversecore_mcp/core/memory.py`
  - `tests/unit/core/test_memory.py`
- **Key findings**:
  - Identified 8 memory tools with completely missing unit test coverage.
  - Discovered a `KeyError` vulnerability due to a potential race condition in `resume_memory_session`.
  - Discovered a UX message inconsistency (bug) in `update_memory_session_time`.
  - Identified SQLite foreign key constraint bypasses in pattern storage.
- **Unexplored areas**: None.

## Key Decisions Made
- Performed detailed read-only code and test coverage analysis.
- Generated 16 specific unit test recommendations (with code snippets, mock configurations, and assertions) in `analysis.md`.
- Finalized findings and written to `handoff.md`.
