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
Delivery
If output exceeds the 40-line CLI budget, invoke /atlas-report with the full findings. The HTML report is the output. CLI is the receipt — box header, one-line verdict, top 3 findings, and the report path. Never dump analysis to CLI.
