- cruncher.js:622-639 (schema)The 'max' tool schema definition, including its name, annotations, description, and inputSchema (accepts an array of 'numbers').
{ name: "max", annotations: { title: "Maximum", readOnlyHint: true, destructiveHint: false, idempotentHint: true, openWorldHint: false, }, description: "Maximum of numbers.", inputSchema: { type: "object", properties: { numbers: { type: "array", items: { type: "number" } }, }, required: ["numbers"], }, }, - cruncher.js:1553-1557 (handler)The 'max' tool handler function that computes the maximum of an array of numbers using Math.max(). Throws if the array is empty.
max: ({ numbers }) => { if (numbers.length === 0) throw new Error("Cannot find the maximum of an empty list."); return Math.max(...numbers); }, - cruncher.js:130-149 (registration)MAIN_THREAD_TOOLS set that includes 'max', indicating it runs on the main thread (no worker overhead).
