What problem does it solve? Before running SageMaker or other AWS operations, agents often guess regions, miss profile overrides, or fail mid-deployment on IAM errors. This Skill reads the local AWS configuration up front so every subsequent command uses the correct profile, region, and account context. ## Core Features & Use Cases - Profile and Region Resolution: Resolves the active profile from AWS_PROFILE or user input, and the region from a strict precedence chain (explicit user input, AWS_REGION, AWS_DEFAULT_REGION, ~/.aws/config) with no hardcoded defaults. - Credential and Identity Validation: Runs aws sts get-caller-identity to confirm credentials work and capture the account ID and caller ARN. - SSO Principal Detection: Identifies SSO assumed-role principals from the ARN pattern and warns early that IAM role creation will likely fail, preventing confusing mid-deployment errors. - Use Case: Before deploying a SageMaker training job, run this Skill to confirm you are in profile 'ml-team', region 'eu-west-1', account '123456789012', and learn immediately that your SSO session cannot create IAM roles. ## Quick Start Discover my current AWS profile, region, account, and caller identity before we start any SageMaker work.
