Subject: [PATCH] fix(trpc): default agent to 'claude' in
 createAutomationSchema for SDK <alpha.10 compat
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

SDK <alpha.10 and any caller predating PR #4481 omit the `agent` field
(previously `agentConfig`) and receive a ZodError BAD_REQUEST.  Adding
`.default('claude')` makes the field optional-on-wire while keeping it
required in the DB — matching the pre-rename behaviour where claude was
effectively the implicit default.

17 BAD_REQUEST errors observed in production since 2026-05-13 12:32 UTC.

Relates to #4481.
