Atmos Validation Framework

For the experimental CEL policy engine, saved-plan guardrails, and policy-required hooks, use atmos-policy. This skill covers the existing validation commands and settings.validation.

Use this skill for every Atmos validation command and validation policy configuration: aggregate project validation, configuration and stack schemas, JSON Schema, OPA/Rego, EditorConfig, GitHub Actions workflows, affected-file selection, and native CI reporting.

For detailed JSON Schema examples, read references/json-schema.md. For OPA/Rego policy patterns, read references/opa-policies.md. For project-wide, affected, and CI validation behavior, read references/project-validation.md.
