Implementation Reference
- src/adapters/aws-adapter.ts:106-116 (handler)Core handler implementation: initializes AWS EC2 client with credentials and sends StartInstancesCommand to AWS to start the specified EC2 instance.
async startEC2Instance(instanceId: string): Promise<void> { await this.initializeClients(); if (!this.ec2Client) throw new Error('EC2 client not initialized'); try { const command = new StartInstancesCommand({ InstanceIds: [instanceId] }); await this.ec2Client.send(command); } catch (error) { throw new Error(`Failed to start instance: ${error instanceof Error ? error.message : String(error)}`); } } - src/tools/aws-tools.ts:165-169 (handler)Tool handler case in handleAWSTool function: extracts instanceId, calls AWSAdapter.startEC2Instance, and returns success message.
case 'aws_start_ec2_instance': { const instanceId = params.instanceId as string; await adapter.startEC2Instance(instanceId); return { success: true, message: `Instance ${instanceId} started successfully` }; } - src/tools/aws-tools.ts:61-78 (registration)Tool registration in awsTools array: defines name, description, and input schema for aws_start_ec2_instance.
