# Plugin Context

> The ctx object passed to a background module's onStart and onStop — every accessor at a glance.

Every background module's [`onStart(ctx)` and `onStop(ctx)`](/sdk/background/overview#the-pluginbackgroundmodule-contract) receive a single `ctx` object: the plugin's scoped gateway to shell infrastructure, live flight state, and the pilot. Each accessor is documented on its own page below.
