• cruncher.js:591-627 (registration)

  Tool 'min' registration in the master tool catalog (toolsAll array). Defines name, annotations, description, and inputSchema requiring an array of numbers.

  {
      name: "median",
      annotations: {
          title: "Median",
          readOnlyHint: true,
          destructiveHint: false,
          idempotentHint: true,
          openWorldHint: false,
      },
      description: "Median of numbers.",
      inputSchema: {
          type: "object",
          properties: {
              numbers: { type: "array", items: { type: "number" } },
              timeout: { type: "number", minimum: 100, maximum: 60000, description: "Custom timeout in ms (100-60000, default: 3000)" },
          },
          required: ["numbers"],
      },
  },
  {
      name: "min",
      annotations: {
          title: "Minimum",
          readOnlyHint: true,
          destructiveHint: false,
          idempotentHint: true,
          openWorldHint: false,
      },
      description: "Minimum of numbers.",
      inputSchema: {
          type: "object",
          properties: {
              numbers: { type: "array", items: { type: "number" } },
          },
          required: ["numbers"],
      },
  },

• cruncher.js:620-626 (schema)

  Input schema for the 'min' tool: requires an array of numbers.

  inputSchema: {
      type: "object",
      properties: {
          numbers: { type: "array", items: { type: "number" } },
      },
      required: ["numbers"],
  },

• cruncher.js:1562-1570 (handler)

  Handler function for the 'min' tool. Iterates over numbers array to find and return the minimum value. Throws error for empty array.

  min: ({ numbers }) => {
      if (numbers.length === 0)
          throw new Error("Cannot find the minimum of an empty list.");
      let minVal = Infinity;
      for (let i = 0; i < numbers.length; i++) {
          if (numbers[i] < minVal) minVal = numbers[i];
      }
      return minVal;
  },

• cruncher.js:82-82 (registration)

  'min' listed in the standard tool tier (TOOL_TIERS.standard) — enabled by default.

  "sum", "avg", "min", "max", "count", "variance", "std_dev",

• cruncher.js:136-155 (helper)

  'min' listed in MAIN_THREAD_TOOLS set, meaning it runs in the main thread without worker overhead for performance.

  const MAIN_THREAD_TOOLS = new Set([
      // Angle management
      "set_angle_mode", "get_angle_mode",
      // Trigonometry (instant Math calls)
      "sine", "cosine", "tangent", "asin", "acos", "atan",
      // Cache management
      "cache_clear", "cache_info",
      // Simple stats (zero-cost)
      "count", "min", "max", "variance", "std_dev",
      // Percentage
      "percentage_of", "percentage_change", "percentage_reverse",
      // Math one-liners
      "power", "sqrt", "logarithm", "natural_log", "absolute",
      // Constant lookup
      "get_constant",
      // Memory recall (single variable read)
      "memory_recall",
      // Unit conversion
      "convert_unit",
  ]);
