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 problem type, business cost function (FP vs FN cost), data distribution, and class balance.

Step 2: Produce Output

Output an evaluation framework: primary/secondary metrics, evaluation split strategy, calibration check, and report template.

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.
