What it does
- Wrong menu IDs: Never use MenuId. from vs/platform/actions for Agents window UI. Always use Menus. from browser/menus.ts.
- Events instead of observables: Session state must flow through IObservable, not Event. Use autorun/derived for reactive UI, not onDid event listeners.
- Importing from providers: Non-provider contrib/ code must never import from contrib/providers/. Extract shared interfaces to services/ or common/.
- Modifying workbench code: Prefer extending/wrapping workbench classes in the sessions layer over modifying shared workbench components.
