@ai-sdk/workflow@2.0.104

Patch Changes

• b161730: fix(workflow): WorkflowAgent now accepts onError and onAbort in the constructor, like ToolLoopAgent. They are called before the callbacks passed to generate() or stream(). An error thrown by an onError or onAbort callback no longer replaces the error or result of the run.
• c591e12: fix(workflow): tools called by WorkflowAgent no longer receive the system prompt or the assistant message that contains the current tool call in options.messages. The messages passed to onToolExecutionStart and onToolExecutionEnd no longer contain the system prompt either. This matches ToolLoopAgent, generateText, and streamText.
• ec23d2d: fix(workflow): model, toolChoice, activeTools, and generation settings returned from prepareStep in WorkflowAgent now apply to the current step only, like in ToolLoopAgent. Before, an override returned for one step stayed in effect for all later steps.
• 1876747: fix(workflow): WorkflowAgent.stream() now aggregates totalUsage the same way as ToolLoopAgent. Token details such as cached and reasoning tokens are kept, and counts that the provider did not report stay undefined instead of becoming 0.
