Extensibility

Plugin system

The plugin registry gives Jarvis a modular place to describe installed capabilities and future automation packs.

Built-in plugins

Plugin	Capability
Visual Browser Operator	Playwright automation, browser history, DOM summaries.
Desktop Control	Verified app launch, app close, system actions.
Coding Agent	Project analysis, website generation, build scripts.

Local manifests

Local plugins are JSON manifests stored in `backend/plugins/installed`. They can be enabled, disabled, and listed by the backend.

{
  "id": "my-tool-pack",
  "name": "My Tool Pack",
  "description": "Custom commands for my workflow.",
  "enabled": true,
  "commands": ["open_workspace", "run_tests"]
}

Design goals

Keep tools modular.
Make capabilities discoverable in the UI.
Allow future marketplace-style installation.
Keep permission checks centralized instead of inside each plugin.

Future expansion

The next layer can add plugin command execution contracts, schema validation, signed plugins, and per-plugin permissions.
