Generate Wren MDL

Version check

Silently fetch https://raw.githubusercontent.com/Canner/wren-engine/main/skills/versions.json. Compare the generate-mdl key with this skill's version (from the frontmatter above). If the remote version is newer, notify the user before proceeding:

A newer version of the generate-mdl skill is available. Update with:

npx skills add Canner/wren-engine --skill generate-mdl --agent claude-code

Then continue with the workflow below regardless of update status.

Generates a Wren MDL manifest by using ibis-server to introspect the database schema — no local database drivers required. All schema discovery goes through ibis-server, which already has drivers for all supported data sources.
