Implementation Reference

• src/tools/navigation.ts:134-174 (handler)

  The "go_to_implementation" tool is registered and implemented in src/tools/navigation.ts. It uses the `prepareSymbolRequest` helper to find the context, then requests `textDocument/implementation` from the LSP, and finally formats the results using `formatLocations`.

  server.registerTool(
    "go_to_implementation",
    {
      title: "Go to Implementation",
      description:
        "Find implementations of an interface or abstract method.",

        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"),
        filter: z
          .string()
          .optional()
          .describe("Optional regex filter on symbol/file names in results"),
        limit: z
          .number()
          .default(50)
          .describe("Max results to return. Default: 50"),
      }),
    },
    async ({
      filePath,
      symbolName,
      symbolKind,
      filter,
      limit,
    }): 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/implementation",
          makePositionParams(prep.ctx)
        );
