# BRIEFING — 2026-06-27T07:35:00+09:00

## Mission
Empirically verify correctness, error pathways, and exception handling of memory tools under stressful conditions.

## 🔒 My Identity
- Archetype: EMPIRICAL CHALLENGER
- Roles: critic, specialist
- Working directory: /Users/sjkim1127/Reversecore_MCP/.agents/challenger_m5_1/
- Original parent: 0c44a811-b4db-47e1-891b-60482d466a84
- Milestone: Milestone 5
- Instance: 1 of 1

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code.

## Current Parent
- Conversation ID: 0c44a811-b4db-47e1-891b-60482d466a84
- Updated: not yet

## Review Scope
- **Files to review**: `reversecore_mcp/tools/common/memory_tools.py`, `tests/unit/tools/common/test_memory_tools.py`
- **Interface contracts**: `PROJECT.md` / `SCOPE.md` / `AGENTS.md`
- **Review criteria**: correctness, coverage, robustness, exception handling

## Attack Surface
- **Hypotheses tested**:
  - Mock store returning incomplete session or context dicts causes unhandled `KeyError`.
  - Passing `None` to `create_memory_session` name propagates unhandled `sqlite3.IntegrityError`.
  - Passing directory to `binary_path` is handled gracefully.
- **Vulnerabilities found**:
  - Unhandled `KeyError` on missing keys like `id`, `name`, `memories` in database context/session replies.
  - Unhandled `IntegrityError` when `name` parameter is null/None.
- **Untested angles**: Concurrency/race conditions on sqlite database locking.

## Loaded Skills
- None loaded.

## Key Decisions Made
- Initial analysis of target source and test files.
