Sample: Sequential workflow (agent-focused API) with shared conversation context
|
|
|
|
Build a high-level sequential workflow using SequentialBuilder and two domain agents.
|
|
The shared conversation (list[ChatMessage]) flows through each participant. Each agent
|
|
appends its assistant message to the context. The workflow outputs the final conversation
|
|
list when complete.
|
|
|
|
Note on internal adapters:
|
|
- Sequential orchestration includes small adapter nodes for input normalization
|
|
("input-conversation"), agent-response conversion ("to-conversation:<participant>"),
|
|
and completion ("complete"). These may appear as ExecutorInvoke/Completed events in
|
|
the stream—similar to how concurrent orchestration includes a dispatcher/aggregator.
|
|
You can safely ignore them when focusing on agent progress.
|
|
|
|
Prerequisites:
|
|
- Azure OpenAI access configured for AzureOpenAIChatClient (use az login + env vars)

Write a tagline for a budget-friendly eBike.

Ride farther, spend less—your affordable eBike adventure starts here.

This tagline clearly communicates affordability and the benefit of extended travel, making it
|
|
appealing to budget-conscious consumers. It has a friendly and motivating tone, though it could
|
|
be slightly shorter for more punch. Overall, a strong and effective suggestion!
