Implementation Reference
- cruncher.js:335-354 (schema)Schema definition for the 'sine' tool: accepts an angle number and optional unit (degrees/radians), angle is required.
{ name: "sine", annotations: { title: "Sine", readOnlyHint: true, destructiveHint: false, idempotentHint: true, openWorldHint: false, }, description: 'Sine. Angle in degrees by default, or radians with unit: "radians".', inputSchema: { type: "object", properties: { angle: { type: "number" }, unit: { type: "string", enum: ["degrees", "radians"] }, }, required: ["angle"], }, }, - cruncher.js:1385-1385 (handler)Handler implementation for the 'sine' tool: converts the angle to radians via toRadians() (using the global angleMode or provided unit), then calls Math.sin().
sine: ({ angle, unit }) => Math.sin(toRadians(angle, unit)), - cruncher.js:1298-1301 (helper)Helper function toRadians that converts degrees to radians, using global angleMode if no unit is specified.
const toRadians = (angle, unit) => { const resolved = unit || angleMode; return resolved === "degrees" ? angle * (Math.PI / 180) : angle; }; - cruncher.js:69-80 (registration)Tool tier registration: 'sine' is listed in the 'standard' tool set (34 tools), making it available by default.
