useComposers(selector) in any plugin component and composers(selector) on every command context return the composer of a running agent, named by id or by focus, whether or not its tab is open.
A running agent now has one store-backed composer model apart from any mounted tab. The mounted composer plugs its cursor-aware insert in while mounted; otherwise insertText and setPrompt write the agent's saved prompt. model and thinking resolve through the provider catalog with the picker's own function, so a read equals what the picker shows.
The host reads one ComposerModel from context and no longer knows whether it is in an agent, a draft or New workspace. The daemon rejects an unlisted model or thinking option for a running agent, replacing the app-side guard.
Draft commands read the state captured at render, so a plugin's
`await setProvider(); await setModel()` acted on a stale provider. The draft
form and options are now plain stores that commands read live, and
`setProvider`/`setModel` reject an unavailable provider or a model the loaded
catalog does not list. Draft `options` include the plugin's pending edits.
Shared composer controls own the pending state and show a rejected command as
an error toast, like the built-in controls. Callback payloads are objects
(`{ value }`, `onPress(event)`) so they can grow without breaking plugins.
The overflow sheet's content portals to the app root and lost the composer's
agent, input, toast and query contexts, so plugin items drew nothing in it.
`useComposerSheetBridge` carries them across.
A plugin registers a component with addComposerItem and reads and changes the
composer through useComposer(): provider, model, mode, thinking, options,
prompt, attachments and agent metadata. The agent, draft and New workspace
composers provide the same ComposerInput and ComposerAgent halves, so a
command reaches the right model without the plugin knowing which composer
it sits in.
Toggle, Select and Action are drawn by one ComposerControl renderer that
the thinking select and provider option controls now use too. Controls sit in
the toolbar when there is room and become rows in the existing overflow sheet
otherwise, so on a phone they appear in the overflow. Plugin items count in
the density presence so the composer condenses to make room. Model and mode
stay specialized but share the trigger, density and overflow.
Draft metadata is kept locally, sent at creation and reset when the prompt is
sent. PluginAgentSnapshot.metadata, deferred from the metadata phase, lands
here. The unused provider badge is removed.
vitest resolves @floating-ui/react-native to its ESM build: the CJS entry
requires the real react-native, whose Flow sources do not parse.
