  Implementation of the "link" tool, which runs `npm link` in the specified directory, optionally linking a specific package.

  server.tool(
    "link",
    "Symlink a local package for development",
    {
      path: z.string().describe("Absolute path to the package directory"),
      package: z.string().optional().describe("Package name to link (omit to link current dir globally)"),
    },
    async ({ path, package: pkg }) => {
      const args = ["link"];
      if (pkg) args.push(pkg);
      try {
        const { stdout, stderr } = await run(args, path);
        return { content: [{ type: "text", text: stdout + stderr }] };
      } catch (e: any) {
        return {
          content: [{ type: "text", text: `Error: ${e.stderr || e.message}` }],
          isError: true,
        };
      }
    },
  );
