Awsflow Lambda

Manage AWS Lambda functions, event source mappings, aliases, versions, and layers.

When to Use This Skill

Use this skill when the user:

• •Asks about Lambda functions or serverless
• •Wants to invoke a Lambda function
• •Needs to update function code
• •Wants to inspect function configuration, concurrency, or URLs
• •Asks about event source mappings (SQS, SNS, DynamoDB, Kinesis triggers)
• •Needs to manage aliases, versions, or layers
• •Wants to tag or untag Lambda resources

Tool: LambdaTool

Execute AWS Lambda commands including event source mappings. ALWAYS provide params object.
