## Task Summary
- **What to build**: Fix unit tests in `tests/unit/tools/analysis/test_signature_tools.py`.
- **Success criteria**: All 18 tests in `tests/unit/tools/analysis/test_signature_tools.py` pass cleanly, and all 1,700+ tests in the codebase pass.
- **Interface contracts**: `tests/unit/tools/analysis/test_signature_tools.py`
- **Code layout**: Python project structure with tests in `tests/` directory.

## Key Decisions Made
- Confirmed that the failing tests were caused by executing real radare2 commands in unit tests (due to mock mismatch) and incorrect assertions targeting the wrong message/hint fields.
- Verified that the current codebase state has correct mocks for `_execute_r2_command` and correct assertions, resolving all 3 failures and passing all 18 unit tests in the file.
