Before running workflows that require external tools, verify the following:

Python 3.10+ — required for rds_commitment_pricing_analyzer.py. If boto3 is missing, offer offline mode for commitment pricing.
AWS CLI v2 — required for upgrade, proxy, and Blue/Green workflows.
Credentials — confirm with aws sts get-caller-identity before live runs. Prefer IAM roles (EC2 instance profiles, ECS task roles, or AWS SSO session credentials) over long-lived IAM user access keys. If long-lived keys are used, ensure they are rotated regularly. For database connections during prechecks, prefer IAM database authentication where supported.

Constraints:

You MUST ONLY check tool existence and MUST NOT invoke the tools here, because that would trigger live calls before the user is ready
You MUST ask before switching to offline mode
