Practice — Agent Design Patterns: From Workflows to Autonomous Agents (10 questions)

A team is building a pipeline that ingests incoming legal documents and needs to: (1) determine which of four document types it is (contract, NDA, invoice, other), (2) run type-specific extraction appropriate to whichever type was found, and (3) have a second LLM call double-check the extracted fields against the source document before anything is written to the database.

1. Name the workflow pattern(s) present in this pipeline, stage by stage, and justify each with the distinguishing question for that pattern.
2. A colleague argues stage 2 should be "orchestrator-worker" because "a worker handles each type." Explain precisely why that's the wrong name for what's described, and what it would take to actually make it orchestrator-worker.
3. Is this pipeline, as a whole, an agent? Justify using the agency-levels framing.
