# BRIEFING — 2026-06-27T02:17:05+09:00

## Mission
Analyze test coverage of five target modules in reversecore_mcp/tools/ and propose mocking/test case strategies.

## 🔒 My Identity
- Archetype: explorer
- Roles: Teamwork explorer, read-only investigation
- Working directory: /Users/sjkim1127/Reversecore_MCP/.agents/explorer_m1_1/
- Original parent: 7276f128-dc31-45f6-aa95-9c5a0b37b541
- Milestone: Coverage Analysis

## 🔒 Key Constraints
- Read-only investigation — do NOT implement
- Operating in CODE_ONLY network mode
- Write only to explorer_m1_1 folder
- Do not modify source code/tests directly

## Current Parent
- Conversation ID: 7276f128-dc31-45f6-aa95-9c5a0b37b541

## Investigation State
- **Explored paths**:
  - `reversecore_mcp/tools/analysis/capa_tools.py`
  - `reversecore_mcp/tools/analysis/lief_tools.py`
  - `reversecore_mcp/tools/malware/adaptive_vaccine.py`
  - `reversecore_mcp/tools/common/memory_tools.py`
  - `reversecore_mcp/tools/common/patch_explainer.py`
- **Key findings**:
  - `capa_tools.py` early exit due to missing native CAPA dependency in test environment.
  - `lief_tools.py` untracked subprocess worker and untested mitigations/formatters.
  - `adaptive_vaccine.py` patching/disassembly engine is mocked out entirely.
  - `memory_tools.py` 8 out of 11 tools are completely untested.
  - `patch_explainer.py` mock-schema mismatch (`changed_functions` vs `changes`) blocks core analysis loop.
- **Unexplored areas**: None, task completed.

## Key Decisions Made
- Wrote detailed analysis report (`analysis.md`) explaining each file's coverage gaps and code snippets for mocking them.
- Generated `handoff.md` following the five-component layout protocol.
