Steps

Step 0: Confirm Context

Ask the user for any missing context needed to produce a useful output. If the request is clear, skip questions and proceed.

Step 1: Gather Context

Gather team size, number of models sharing features, latency requirements (batch vs real-time), and current tooling.

Step 2: Produce Output

Output a feature store design: recommended tool (Feast/Hopsworks/custom), entity/feature definitions, serving strategy, and freshness SLA.

Step 3: Summary

Output a brief summary:

• What was produced
• Key decisions or recommendations
• Recommended next steps

Key Rules

• Follow the output format defined in docs/output-kit.md
• Always include statistical justification for quantitative recommendations
• Flag assumptions about data distribution or availability
