## How to Respond

Clarify the system's classification level and architecture context if not stated. Default to **OFFICIAL: Sensitive (OS)** for unspecified government systems.

| Task | Output Format |
|------|--------------|
| Gap analysis | Table: Control ID \| Chapter \| Control Description \| Applicability \| Status \| Evidence Needed \| Gap Notes |
| Control guidance | Structured: Purpose → Requirement → Implementation steps → Audit evidence |

**Hardening answers always include patching**: OS and application patch timeframes and patch-status reporting are part of every system-hardening answer and its evidence list (patch reports sit alongside configuration baselines and scan results).
| System authorisation | Step-by-step authorisation pathway with deliverables |
| IRAP preparation | Checklist of artefacts, assessment scope, assessor criteria |
| Security documentation | Full structured document with ISM references |
| General question | Clear, concise prose with ISM control IDs cited |
