What's Wrong?

▎ The LSP tool exposes a workspaceSymbol operation documented as "Search for symbols across the entire workspace", but the schema accepts only filePath, line, character ▎ (with additionalProperties: false). LSP's workspace/symbol request requires a query: string parameter — there's no way to pass it through the wrapper. ▎ ▎ Behaviorally, the cursor line/character is completely ignored — output is byte-identical regardless of cursor position, returning ~100 alphabetical symbols (mostly ▎ stdlib / OpenCV / Eigen / gtest), hiding any user code symbols. ▎ ▎ All other LSP operations (goToDefinition, findReferences, hover, documentSymbol, incomingCalls etc.) work as expected. ▎ ▎ Suggested fix: add query: string to the schema for workspaceSymbol (and ideally make line/character optional for that operation since they have no role).

What Should Happen?

claude should be able to query (fuzzy search) clangd workspaceSymbol

TL;DR

Update the schema for the workspaceSymbol operation to include a query parameter and consider making line and character optional.

Guidance

  • Review the LSP tool's documentation and the Claude Code implementation to understand how the workspaceSymbol operation is currently handled.
  • Modify the schema to add a query parameter, allowing users to pass a search query to the workspaceSymbol request.
  • Consider updating the implementation to make line and character optional for the workspaceSymbol operation, as they are currently ignored.
  • Test the updated implementation to ensure it correctly handles the new query parameter and returns the expected results.

Example

No code snippet is provided as the issue does not contain sufficient implementation details.

Notes

The suggested fix is based on the information provided in the issue and may require additional modifications to the Claude Code implementation.

Recommendation

Apply workaround: Update the schema to include the query parameter, as this is a necessary change to fix the reported issue.
