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 data types, missingness rates, outlier concerns, and deduplication requirements.

Step 2: Produce Output

Output a cleaning pipeline: missingness handling strategy, outlier treatment, dedup logic, and audit log design.

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.
