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 API maturity, customer tier mix (enterprise/startup/hobbyist), and current versioning approach.
Step 2: Produce Output
Output a versioning policy: semver rules for this API, deprecation timeline, communication channels (email/blog/banner), and exception process for emergency breaking changes.
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.
