The GitHub picker showed "No results found." for any running agent after
the first message was sent. useAgentInputDraft owned a local cwd state
that clear("sent") wiped to "", so the composer read cwd: "" even though
the agent's real cwd was correct on the wire.
Drop cwd ownership from the hook. Composer takes cwd as a prop sourced
by the parent — agentState.cwd for running agents, composerState.workingDir
for drafts, sourceDirectory for setup flows. The hook now persists only
{text, attachments}. Legacy persisted drafts with a cwd field still
hydrate; tagged COMPAT(draft-cwd) for removal after 2026-11-09.
Also moves attachment pills back inside the composer's bordered surface
via a new attachmentSlot prop on MessageInput, and shrinks pill height
from 48 to 32 — the subagents-track tuck previously had attachments
floating between it and the input.
Adds one Playwright spec asserting the draft-create-agent path submits
the workspace cwd.
Extract DraftStorage interface and createAgentInputDraftCore factory
to a new use-agent-input-draft-core.ts. Pure helper functions (resolveDraftKey,
resolveEffectiveComposerModelId, etc.) move there too, breaking the test
file's transitive dependency on AsyncStorage and useAgentFormState.
The test now imports directly from the core module, uses a Map-backed
in-memory storage, and has zero vi.mock calls. Tests assert behavior
("save then load returns the same draft") rather than call counts.
