Which JSON Schema versions are supported?

The skill supports JSON Schema Draft-04, Draft-06, Draft-07, 2019-09, and 2020-12. It can automatically detect the version or allow manual specification.

What does the --strict flag do?

The strict flag enables additional rules, such as disallowing unknown keywords, requiring the $schema declaration, and enforcing format assertions.

Can this skill help fix invalid schemas?

Yes, by providing specific error paths and descriptive messages (e.g., 'type must be a string'), it helps Claude identify and fix structural errors in your schema files.

What is the difference between this and regular schema validation?

Regular validation (schema-validate) checks if data matches a schema. This meta-validator (schema-meta) checks if the schema itself is correctly written according to JSON Schema standards.

Desarrollo de API

Validates JSON Schema documents against official specifications to ensure structural integrity and syntax compliance.

Acerca de

The JSON Schema Meta-Validator skill provides Claude with the specialized ability to verify that JSON Schema files are well-formed and strictly conform to official draft specifications. It supports a wide range of versions, from Draft-04 to 2020-12, and includes a strict mode for identifying non-standard keywords or missing declarations. This skill is indispensable for developers building APIs, data models, or configuration systems, ensuring that the schemas defining their data are technically sound before they are deployed or used for data validation.
