When does this happen?

IF Deciding whether to use a single Claude API call, a workflow with tool use, or Managed site_1.

How others solved it

THEN Start simple: use single API calls for classification, summarization, extraction, Q&A. Use workflow (API + tool use) for multi-step pipelines you orchestrate. Use Managed site_1 only when you want Anthropic to run the agent loop and host a container for tool execution. Check if deploying via third-party provider (Bedrock/Vertex/Foundry) — if so, Managed site_2 is unavailable; use Claude API + tool use for all agent needs.
