Implementation Reference

• src/tools/navigation.ts:100-125 (handler)

  The handler function for the get_hover tool, which prepares the symbol request and calls the LSP's textDocument/hover method.

  async ({ filePath, symbolName, symbolKind }): Promise<ToolResult> => {
    try {
      const prep = await prepareSymbolRequest(lsp, filePath, symbolName, symbolKind);
      if ("error" in prep) return textResult(prep.error);
  
      const result = await lsp.request(
        "textDocument/hover",
        makePositionParams(prep.ctx)
      );
  
      if (!result) return textResult("No hover information available.");
  
      const contents = result.contents;
      if (!contents) return textResult("No hover information available.");
  
      if (typeof contents === "string") return textResult(contents);
      if (contents.value) return textResult(contents.value);
  
      if (Array.isArray(contents)) {
        const parts: string[] = [];
        for (const item of contents) {
          if (typeof item === "string") parts.push(item);
          else if (item.value) parts.push(item.value);
        }
        return textResult(parts.join("\n"));
      }

• src/tools/navigation.ts:88-99 (registration)

        "Get hover documentation and type info for a symbol.",
      inputSchema: z.object({
        filePath: z.string().describe("Absolute path to the file"),
        symbolName: z.string().describe("Name of the symbol to find"),
        symbolKind: z.string().optional().describe("Kind of symbol"),
      }),
