# BRIEFING — 2026-06-26T22:23:16Z

## Mission
Verify formatting, linting, and correctness of `tests/unit/tools/common/test_memory_tools.py`.

## 🔒 My Identity
- Archetype: reviewer_and_adversarial_critic
- Roles: reviewer, critic
- Working directory: /Users/sjkim1127/Reversecore_MCP/.agents/reviewer_m5_3/
- Original parent: 0c44a811-b4db-47e1-891b-60482d466a84
- Milestone: Milestone 5 Format Review (memory_tools.py coverage)
- Instance: 3

## 🔒 Key Constraints
- Review-only — do NOT modify implementation code.
- Ensure strict compliance with formatting (black) and linting (ruff).
- Run and verify target tests pass.
- Write handoff.md in working directory.

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

## Review Scope
- **Files to review**: `tests/unit/tools/common/test_memory_tools.py`
- **Interface contracts**: `PROJECT.md`, `reversecore_mcp/tools/common/memory_tools.py`
- **Review criteria**: formatting (black), linting (ruff), correctness, conformance

## Key Decisions Made
- Initial decision: Validate test file using black and ruff, run test suite, and perform adversarial critic evaluation.

## Artifact Index
- /Users/sjkim1127/Reversecore_MCP/.agents/reviewer_m5_3/handoff.md — Handoff report and review verdict.

## Review Checklist
- **Items reviewed**:
  - `tests/unit/tools/common/test_memory_tools.py`
  - `reversecore_mcp/tools/common/memory_tools.py`
  - `reversecore_mcp/core/memory.py`
- **Verdict**: APPROVE
- **Unverified claims**: None.

## Attack Surface
- **Hypotheses tested**:
  - Hashing large files via `read_bytes` could trigger Out-Of-Memory (OOM) error (Confirmed).
  - Lack of database range constraint for `importance` field could accept out-of-bounds/invalid inputs (Confirmed).
- **Vulnerabilities found**:
  - Memory OOM vulnerability when calculating hash of large files.
  - Lack of input validation/DB constraints on the `importance` integer range in `save_memory_item`.
- **Untested angles**:
  - Actual SQLite file corruption scenarios.
