## 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
