# Docstring Coverage Plan - 100% Target

## Summary
- Total Missing: 1,690 docstrings
- Current Coverage: 86.7%
- Target Coverage: 100%

- [ ] tests/utils/performance.py - 14 missing
- [ ] tests/utils/validation.py - 2 missing

### 2. Root Test Files
- [ ] tests/__init__.py - 1 missing (module-level)
- [ ] tests/core/__init__.py - 1 missing (module-level)
- [ ] tests/ipc_socket_utils.py - 2 missing
- [ ] tests/test_import.py - 1 missing (module-level)

### 3. Test Core Files

- [ ] tests/core/test_tool_base_coverage.py - 9 missing
- [ ] tests/core/test_compatibility_coverage.py - 47 missing

- [ ] nodupe/core/api/decorators.py - inner functions
- [ ] output/ci_artifacts/setup.py - 1 missing

## Strategy
1. Start with simplest fixes (module-level docstrings)
2. Move to production code fixes
3. Handle test files systematically
4. Use subagents for parallel work on different categories
