Implementation Reference

• src/index.ts:45-67 (handler)

  The 'list_categories' tool handler that executes the tool logic. It retrieves the platform registry, maps over CATEGORIES to build category info with platform counts (total, builtin, custom), and returns JSON formatted output.

  server.tool(
    "list_categories",
    "List all available prompt optimization categories with platform counts including custom platforms",
    {},
    async () => {
      const registry = getPlatformRegistry();
      const cats = await Promise.all(CATEGORIES.map(async c => {
        const allPlatforms = await registry.getPlatformsForCategory(c.id);
        return {
          id: c.id,
          label: c.label,
          description: c.description,
          has_platforms: c.hasPlatforms,
          platform_count: allPlatforms.length,
          builtin_count: c.platforms?.length ?? 0,
          custom_count: allPlatforms.filter(p => p.isCustom).length,
          default_platform: c.defaultPlatform ?? null,
          default_mode: c.defaultMode,
        };
      }));
      return { content: [{ type: "text" as const, text: JSON.stringify(cats, null, 2) }] };
    }
  );

• src/index.ts:48-48 (schema)

  Empty input schema `{}` for list_categories tool, indicating no parameters required.

  {},

• src/engine/config/registry.ts:12-25 (helper)

  PlatformRegistry.getPlatformsForCategory method used by the handler to fetch both built-in and custom platforms for each category.

  async getPlatformsForCategory(categoryId: Category): Promise<PlatformConfig[]> {
    await this.store.ensureLoaded();
    const builtIn = getBuiltInPlatforms(categoryId);
    const custom = this.store.getCustomPlatforms(categoryId).map(entry => ({
      id: entry.id,
      label: entry.label,
      description: entry.description,
      syntaxHints: entry.syntaxHints,
      instructions: entry.instructions,
      instructionsFile: entry.instructionsFile,
      isCustom: true as const,
    }));
    return [...builtIn, ...custom];
  }

• src/engine/config/categories.ts:18-26 (schema)

  CategoryConfig interface defining the structure of category data returned by list_categories, including id, label, description, platforms, defaultPlatform, defaultMode, and hasPlatforms.

  export interface CategoryConfig {
    id: Category;
    label: string;
    description: string;
    platforms?: PlatformConfig[];
    defaultPlatform?: string;
    defaultMode: Mode;
    hasPlatforms: boolean;
  }

• src/engine/config/categories.ts:107-115 (helper)

  CATEGORIES constant - the source data array containing all 7 category definitions (chat, image, voice, video, music, code, document) that the handler iterates over.

  export const CATEGORIES: CategoryConfig[] = [
    { id: 'chat', label: 'Chat', description: 'General conversation & Q&A', platforms: CHAT_PLATFORMS, defaultPlatform: 'claude', defaultMode: 'detailed', hasPlatforms: true },
    { id: 'image', label: 'Image', description: 'Image generation', platforms: IMAGE_PLATFORMS, defaultPlatform: 'midjourney', defaultMode: 'detailed', hasPlatforms: true },
    { id: 'voice', label: 'Voice', description: 'Voice & speech synthesis', platforms: VOICE_PLATFORMS, defaultPlatform: 'elevenlabs', defaultMode: 'detailed', hasPlatforms: true },
    { id: 'video', label: 'Video', description: 'Video generation', platforms: VIDEO_PLATFORMS, defaultPlatform: 'runway', defaultMode: 'detailed', hasPlatforms: true },
    { id: 'music', label: 'Music', description: 'Music generation', platforms: MUSIC_PLATFORMS, defaultPlatform: 'suno', defaultMode: 'detailed', hasPlatforms: true },
    { id: 'code', label: 'Code', description: 'Programming & development', platforms: CODE_PLATFORMS, defaultPlatform: 'claude', defaultMode: 'detailed', hasPlatforms: true },
    { id: 'document', label: 'Document', description: 'Writing & documents', platforms: DOCUMENT_PLATFORMS, defaultPlatform: 'claude', defaultMode: 'detailed', hasPlatforms: true },
  ];
