Agent AppInstallable intelligent applications.

A packaging standard for complete intelligent apps with UI, workflows, storage, and SDK-bound host capabilities.

Runtime package

APP.md is discovery only; real UI, workers, storage, workflows, and business implementation live in the runtime package.

Apps call Lime through stable capabilities such as lime.ui, lime.storage, lime.agent, and lime.artifacts instead of internals.

References Skills, Knowledge templates, Tools, Artifacts, Evals, UI entries, Context, Evidence, Policy, and QC.

A host platform opens capabilities; apps declare entries and permissions; users install apps into a local environment.

Contract	Question answered

Capabilities	Which host standards and capability surfaces does this app need?
Knowledge templates	Which Agent Knowledge slots must the user or tenant bind?
Projection	How does a host compile the app into a catalog without inventing a second runtime?
Readiness	What must be installed, authorized, or reviewed before the app can run?
