What does the validate-md skill actually check?

It validates the YAML frontmatter section located at the top of Markdown files against a predefined schema.yaml file using the JSON Schema standard.

How do I define the rules for my Markdown files?

You define your rules in a file named 'schema.yaml' placed within the directory of the Markdown files you wish to validate.

Do I need to install additional software for this skill?

Yes, you must have Python installed along with the 'pyyaml' and 'jsonschema' packages to execute the validation scripts.

Does it support nested YAML objects?

Yes, since it uses JSON Schema, it can validate deeply nested objects, arrays, and complex data types within your Markdown metadata.

Validates Markdown files and YAML frontmatter against JSON Schema definitions to ensure data integrity.

关于

The Markdown Schema Validator (validate-md) is a specialized tool for Claude Code designed to automate the verification of structured metadata within Markdown files. By comparing YAML frontmatter against a local schema.yaml file, it ensures that all required properties, data types, and formatting constraints are met. This is particularly useful for developers managing static site generators, documentation-as-code, or flat-file databases where inconsistent metadata can lead to build failures or data corruption. It provides clear, actionable error messages that pinpoint exact file locations and missing fields.
