Daymade skills core suite. Bundles skill creation, quality review, governance, and marketplace development tooling under one shared namespace. Existing-skill edits use an old-vs-new capability audit and content-bound packaging attestation so prompt compression cannot silently delete runtime contracts. When the official skill-creator plugin is also installed, skill-creator detects the coexistence and offers a consent-based, reversible SessionStart routing hook so the daymade edition wins deterministically; on machines without the official plugin nothing is ever installed.
Quality-gated skill authoring: create, recap, update, judge, and step-through-apply skills with HITL and an audit/feedback layer.
