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 target endpoints, expected traffic patterns (concurrency, request rate), payload sizes, and SLA requirements.

Step 2: Produce Output

Output a benchmark design: test scenarios (read/write/mixed), tooling (k6/wrk/hey), metrics to capture, baseline targets, and CI integration plan.

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
  • Optimize for developer time-to-value — every recommendation should reduce friction
  • Flag when output needs to be tested against the actual API or developer workflow

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.
