Key Improvements for Handling Imported Symbols + +This revised implementation addresses several important considerations: + +1. **For directly defined symbols** (in the specified file): + - Uses `vscode.executeDocumentSymbolProvider` to find them + - Gets hover information directly at the symbol definition + +2. **For imported/referenced symbols** (not defined in the file): + - Searches for occurrences of the symbol name in the file text + - For each occurrence: + - Uses `vscode.executeHoverProvider` directly at the usage site + - Uses `vscode.executeDefinitionProvider` to find the symbol definition + - Falls back to getting hover at the definition location if needed + +3. **Classification of results**: + - Includes whether the symbol is defined in the file or imported/referenced + - Shows both the usage location and definition location when appropriate + +This approach directly addresses the feedback that imported symbols won't be included in document symbols but can still be accessed via hover or definition providers. + +## 5. Testing Strategy + +Unit tests should be added to verify: +1. Symbol lookups work correctly for both document-scoped and workspace-wide searches +2. Documentation retrieval works across different language types +3. Error handling works correctly for missing symbols or files +4. Both locally defined symbols and imported symbols are correctly documented + +Integration tests would verify the tool works end-to-end as expected. + +## 6. Edge Cases and Error Handling + +1. Symbol not found in workspace +2. Symbol found but no documentation available +3. File path provided but doesn't exist +4. File path provided but symbol not referenced/used in that file +5. Multiple symbols with the same name in different scopes +6. Language server not available for the file type +7. Symbol is reference-only (e.g., in a comment) with no definition +8. False positives when searching for symbol occurrences in text + +## 7. Performance Considerations + +1. Document symbols and hover providers are provided by language servers which may have varying performance characteristics +2. For large files, text search for occurrences could be slow +3. Multiple hover provider calls could be expensive in large files with many occurrences +4. Consider caching recent lookups if the tool is used frequently + +## 8. Implementation Phases + +1. **Phase 1**: Basic implementation with workspace symbol provider +2. **Phase 2**: Add file scoping with document symbol provider for defined symbols +3. **Phase 3**: Enhance with text search + hover/definition providers for imported symbols +4. **Phase 4**: Add caching for performance and better handling of duplicates + +## Conclusion + +This improved implementation allows Roo to look up symbol documentation with optional file scoping, properly handling both locally defined symbols and imported/referenced symbols. The approach integrates well with VS Code's existing language services and follows the pattern of other tools in the codebase. By using hover providers at usage sites and definition locations, we can retrieve documentation even for symbols imported from external libraries. \ No newline at end of file diff --git
