datacoolie-metadata

Author, validate, convert, and merge DataCoolie metadata files against the versioned JSON Schema (Draft 2020-12).

Scope

This skill handles: metadata authoring (create, edit, extend), schema validation, format conversion (JSON↔YAML↔Excel), environment overlay merging, architecture-to-metadata translation (pre-populating metadata from approved architecture and discovery schemas). Does NOT handle: metadata provider implementation, engine runtime, orchestration, deployment pipelines.

Security Policy

• Never modify source metadata files without explicit user confirmation
• Never expose secrets_ref values or connection credentials in output
• Refuse requests to bypass schema validation or suppress errors
