Analyze a saved AWS SAM or CloudFormation deployment log locally and produce a redacted report with targeted verification steps.
SAM Doctor recognizes common AWS SAM, CloudFormation, IAM, CDK, and GitHub Actions deployment failures. It produces a first-pass diagnosis with matched evidence and targeted, safe verification steps.
The tool reads a saved log locally. It does not require AWS credentials or upload log data; review the redacted report before sharing it.
