Worked on hardening the agentless scanning workflow in the DataDog/terraform-provider-datadog repository by implementing strict validation for AWS Account IDs within the Terraform provider. Focused on schema validation using Go and HCL, the work enforced a 12-digit numeric format for account IDs, directly reducing misconfigurations and deployment errors. Extended automated test coverage to include invalid account scenarios, improving regression safety and maintainability. The approach emphasized clear traceability by linking validation logic to specific commits, ensuring that future changes remain auditable. This effort enhanced the reliability of agentless scanning deployments and contributed to the overall robustness of the provider’s codebase.
