Vercel AI SDK 7.0.107 fixes deferred tool discovery in WorkflowAgent and preserves skill upload APIs through wrapProvider
Published 2026-09-18, [redacted] is a patch batch whose agent-relevant entries are deferred tool discovery support in WorkflowAgent, preservation of provider file and skill upload APIs when a provider is wrapped, passing tool-specific context to input callbacks, and preventing preliminary tool outputs from completing a chat early. It also fixes chat reconnect URLs dropping query parameters and multiple Set-Cookie headers collapsing in Node stream responses. Nothing here is new capability, but the wrapProvider and preliminary-output fixes both remove silent failure modes in agent middleware stacks.
