-- [ ] Update plan as complete
+- [x] Run pre-push script
+- [x] Verify all tests pass
+- [x] Update plan as complete
+
+**Implementation Notes:**
+- Pre-push script passed: linting, formatting, type checking, all 55 tests
+- **76% test coverage** maintained throughout implementation
+- **ASCII detection fix** resolved integration test failures
+- All encoding auto-detection working correctly across the codebase
+
+## Implementation Complete
+
+**Summary**: Successfully replaced encoding parameters with chardet auto-detection across all 4 MCP tools and internal functions. API simplified, reliability improved, all tests passing.
+
+**Key Changes**:
+- Added `detect_file_encoding()` with 0.7 confidence threshold and ASCII→UTF-8 conversion
+- Removed encoding parameters from 15+ functions across 4 files
+- Updated MCP schemas, documentation, and examples
+- Maintained backward compatibility through graceful fallbacks
