Remarks

The config validate command checks that:

• The configuration file exists and is valid JSON
• The configuration matches the specified $schema
• All referenced plugin paths exist and can be loaded
• URL patterns are syntactically correct

Note

Schema validation only applies to JSON-based configuration files. YAML configuration files aren't validated against schemas at runtime.

Use this command in CI/CD pipelines to catch configuration errors before deploying.
