Manifest-First Applet
Start with applet.json plus a manifest-declared main.lua, main.py, or main.cs entrypoint, then request only the capabilities the applet needs.

Capability patterns
Starting points grounded in current YAAA.app capabilities
YAAA applets are manifest-first local automations: review the manifest, entrypoint, requested capabilities, optional provider connections, and package authorization before sensitive work runs.
AI Companion Review
The AI companion can inspect applets and editor state through app-owned controls, while live operation of every applet and editor remains in active development.
Sealed Premium Plugin
Premium plugins must verify, authorize, and decrypt before loading; wrong user, missing entitlement, invalid identity, or tampered package is denied.
GUI Designer Applet
Use the GUI Designer model tree, widgets, layout commands, bindings, preview, diagnostics, assets, components, and tokens for applet interfaces.
Code Editor Workflow
Use the Code Editor plugin for applet source work when the matching editor package is installed and authorized.
PDF Markup Workflow
Use the PDF Editor for review markup such as highlights, notes, shapes, comments, import/export, redaction, forms, measurement, and signing-related tools.
Capability-Gated Run
Applets run with only the capabilities requested and granted; denied capabilities fail closed before dispatch or protected access.
Entitlement-Locked Package
Developers can require a signed entitlement so only designated authenticated users can install, decrypt, or run a protected applet or plugin.
Local-First Operation
Automations run on the user machine by default, with cloud, AI provider, license, update, telemetry, storage, or network connections configured explicitly.
Ready to adapt an applet?
Start with the manifest, inspect the entrypoint, keep requested capabilities narrow, and configure optional services only when the workflow needs them.
