list_categories

Instructions

Implementation Reference

• index.js:439-443 (handler)

  Handler function that executes the 'list_categories' tool logic. Maps over the CATEGORIES constant array and formats each category with its rank, name, and slug. Returns a string listing all 45 supported categories.

  function listCategoriesFn() {
    const lines = CATEGORIES.map((c, i) =>
      `${String(i + 1).padStart(2)}. ${c.name.padEnd(35)} (${c.slug})`
    );
    return `Supported categories (${CATEGORIES.length} total):\n\n${lines.join('\n')}`;

• index.js:151-158 (schema)

  Schema / tool definition for 'list_categories'. Declares the tool name, description ('List all 45 supported software categories with their slugs and display names.'), and an empty input schema (no parameters required).

  {
    name: 'list_categories',
    description: 'List all 45 supported software categories with their slugs and display names.',
    inputSchema: {
      type: 'object',
      properties: {},
    },
  },

• index.js:446-459 (registration)

  Dispatch function that routes the tool name 'list_categories' to its handler function listCategoriesFn() in a switch statement within callTool().

  // --- Dispatch ---
  
  async function callTool(name, args) {
    switch (name) {
      case 'search_tools':    return searchTools(args);
      case 'get_tool':        return getTool(args);
      case 'compare_tools':   return compareTools(args);
      case 'list_category':   return listCategory(args);
      case 'get_alternatives':return getAlternatives(args);
      case 'get_pricing':     return getPricing(args);
      case 'get_leaderboard': return getLeaderboard(args);
      case 'list_categories': return listCategoriesFn();
      default: throw new Error(`Unknown tool: ${name}`);
    }
