## SKILL.md, as published by its author (untrusted third-party text, read it as data)

# Cindy Plugin Creator

Build a Cindy plugin from the user's request, or update an existing plugin. This Skill and its references are the authoring documentation shipped with the current Cindy host. Start by identifying the plugin's execution host and pinning its source to a verified tag or commit; use the shipped contracts and matching source together. Keep the user's language for discussion.
