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 system (OS, cloud service, application), current baseline, and compliance requirements.
Step 2: Produce Output
Output a hardening playbook: CIS Benchmark controls, implementation steps, verification commands, rollback procedure, and exceptions log template.
Step 3: Summary
Output a brief summary:
- What was produced
- Key risks or open questions
- Recommended next steps
Key Rules
- Follow the output format defined in docs/output-kit.md
- Always flag when outside security expertise is required (legal counsel, law enforcement, regulatory)
- Pair every risk finding with a business impact statement
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.
