Two sample questions
D1
An insurer processes claim forms. Every claim goes through the same three steps: extract fields, check them against the policy database, then draft a decision letter. Auditors need each step's output inspected before the next runs. Which design fits best?
- An autonomous agent given all three capabilities as tools and left to choose the order
- One large prompt that performs all three steps at once and returns the final letter
- A coordinator agent that spawns a separate subagent for each claim field it extracts
- A prompt-chained workflow with a programmatic validation check between steps
D1
A research assistant writes market reports. The subtopics worth investigating depend on each question and cannot be listed in advance; results must be merged into one report. Which pattern is the best fit?
- Prompt chaining: a fixed sequence of calls that each handle one predefined report section
- Orchestrator-workers: a lead model breaks down the task, delegates subtasks to workers, then synthesizes
- Routing: classify each question once and send it to a single specialized prompt for the whole of the report
- Parallel voting: run the same full report prompt several times and keep the most common answer
