Which JSON Schema versions are compatible?

The skill supports all major JSON Schema drafts, including Draft 4, 6, 7, 2019-09, and 2020-12.

What happens if a JSON file lacks a $schema property?

The skill will return an informative error and suggest using the related 'schema-validate' skill to manually specify an external schema file.

Can I see multiple validation errors at once?

Yes, by utilizing the --all-errors flag, the tool will report every validation failure found in the document rather than stopping at the first error.

Does this skill support remote schema URLs?

Yes, it can fetch schemas from remote URLs and includes a 24-hour caching mechanism to ensure performance and reduce network requests.

What is the schema-check skill for Claude Code?

It is a specialized utility that allows Claude to validate a JSON file against the schema specified in its own $schema property, ensuring the file follows its declared structure.

API開発

Validates JSON files automatically using their embedded $schema references to ensure data integrity and structural compliance.

概要

The schema-check skill enables Claude to perform automated validation on self-describing JSON documents by resolving the reference found in the $schema property. It supports a wide range of JSON Schema versions, from Draft 4 to 2020-12, and can resolve both local file paths and remote URLs. With built-in caching for remote resources and support for strict validation modes, this tool is ideal for developers who need to verify configuration files, API contracts, or complex data structures directly within their coding environment without manually specifying external schema files.
