# BRIEFING — 2026-06-26T22:18:00Z

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

## Task Summary
- **What to build**: Comprehensive unit tests for `reversecore_mcp/tools/common/memory_tools.py` incorporating pre-designed tests and patches from explorer agents.
- **Success criteria**:
  - All tests in `tests/unit/tools/common/test_memory_tools.py` pass.
  - Coverage for `reversecore_mcp/tools/common/memory_tools.py` is >= 75%.
  - No regressions in other parts of the codebase.
- **Interface contracts**: `AGENTS.md` and `PROJECT.md` if present.
- **Code layout**: Source in `reversecore_mcp/tools/common/memory_tools.py`, tests in `tests/unit/tools/common/test_memory_tools.py`.

## Key Decisions Made
- Overwrote `tests/unit/tools/common/test_memory_tools.py` to incorporate the pre-designed extended mock store.
- Added tests for `sqlite3.OperationalError` during database initialization.
- Added test for hashing failures in `create_memory_session`.
- Strengthened the registration test assertions to verify exact tool names.

## Artifact Index
- `/Users/sjkim1127/Reversecore_MCP/tests/unit/tools/common/test_memory_tools.py` — Updated unit test file for memory tools.

## Change Tracker
- **Files modified**:
  - `tests/unit/tools/common/test_memory_tools.py` — Added 18 new test cases and improved existing assertions.
- **Build status**: Pass (100% coverage on target file `reversecore_mcp/tools/common/memory_tools.py`)
- **Pending issues**: None

## Quality Status
- **Build/test result**: Pass (All 1,686 tests in the test suite pass, 100% coverage on target file `reversecore_mcp/tools/common/memory_tools.py`)
- **Lint status**: Clean (Ruff and Black checks passed successfully)
- **Tests added/modified**: Added edge cases (hashing failure, DB init failure), exception handling paths, and tool registration validation.

## Loaded Skills
- **Source**: google-antigravity-sdk (/Users/sjkim1127/.gemini/config/plugins/google-antigravity-sdk/skills/google-antigravity-sdk/SKILL.md)
