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.
addNewWorkspaceItem mounts a plugin field on the New workspace screen, and
useNewWorkspace() exposes host, project, isolation, base ref, branch and
metadata with commands that follow the composer item rules: they act on the
screen's state when they run, resolve once applied, reject while the screen
is locked, and take JSON payloads. Host and project are read-only because a
command that switched them would unmount the item that called it.
The screen's pickable state (base selection, manual isolation, branch,
metadata) moves into one plain store so pickers and plugin commands write to
the same place; the screen reports derived facts to it on each render. The
branch is sent as source.branchName only for a branch-off worktree, and
metadata on workspace.create.
Items render through ComposerControl with a new "field" surface (badge on
desktop, full-width field when compact). Combobox ships here: Paseo owns the
loading and error states, keeps previous results, and drops superseded
searches.
A draft kept `null` as an option value, so `setOptions({ key: null })` sent the null to the
provider and creation failed. A null edit now removes the key from every draft layer, as the patch
does on a running agent. A running agent's `setModel` accepted ids its catalog does not list; it
now rejects them the way a draft does.
The composer controls imported the toast host through the toast context, which pulled the host's
animation module into every module that loads plugins. They use the API-only context instead.
The migration guide's registration table gets the `addComposerItem` row its test requires.
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.
