Mini-program analogy

WeChat Mini Programs inspired the host-platform mental model: package downloaded locally, manifest declares entries, host provides APIs, and permissions are mediated by the platform. Agent App adapts the pattern to AI hosts and existing Agent standards rather than copying page technology.

Checklist

• Keep declarations machine-readable.
• Keep procedures in Agent Skills.
• Keep facts in Agent Knowledge.
• Keep execution in the host runtime.
• Attach app provenance to projected objects.
