dependencies

The workflow-level dependencies field declares the tool versions a workflow requires, so Atmos can provision them before any step runs.

workflows:
  validate:
    dependencies:
      tools:
        tflint: "^0.54.0"
        checkov: latest
    steps:
      - command: terraform validate vpc
      - command: tflint --recursive
        type: shell

Atmos installs missing tools and prepares PATH before running the workflow.

Version Values

Dependency versions support the same toolchain version forms used elsewhere in Atmos:

Value	Meaning
1.10.3	Exact version
~> 1.10.0	Compatible patch releases
^1.10.0	Compatible minor releases
latest	Latest available version

Use project-wide .tool-versions files for common tool versions and workflow dependencies for workflow-specific requirements.
