+**Validation:**
+
+The `--validate` flag enables GitHub Actions workflow schema validation and container image validation. By default, validation is disabled for faster compilation. Enable it when you need to verify workflow correctness or validate that container images exist and are accessible.
+
 **Strict Mode:**
 
 Enables enhanced security validation requiring timeouts, explicit network configuration, and blocking write permissions. Use `--strict` flag or `strict: true` in frontmatter.
