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