    const packages = WorkspaceDetector.getInstalledPackages(this.config.rootPath);
    
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify({
            config: this.config,
            installedPackages: packages.length,
            packagesWithTypes: packages.filter(p => p.hasTypes).length,
            packages: packages.slice(0, 20) // Limit to first 20 for readability
          }, null, 2)
        }
      ]
    };
  }
