Implementation Reference
- The executeTool switch case that implements the set_tempo tool: validates the bpm input, prepends a setcpm(bpm) line to the current pattern, writes the updated pattern to the editor, and returns a confirmation message.
case 'set_tempo': InputValidator.validateBPM(args.bpm); const currentTempo = await this.getCurrentPatternSafe(); const withTempo = `setcpm(${args.bpm})\n${currentTempo}`; await this.writePatternSafe(withTempo); return `Set tempo to ${args.bpm} BPM`; - The tool definition in getTools() including name, description, and input schema requiring a numeric bpm parameter. This is used for both listing tools and validation.
{ name: 'set_tempo', description: 'Set BPM', inputSchema: { type: 'object', properties: { bpm: { type: 'number', description: 'Tempo in BPM' } }, required: ['bpm'] } - Array in requiresInitialization() helper function that includes 'set_tempo' among tools requiring browser initialization before execution.
