How to Respond

Match output format to task type:

TaskOutput Format
Control family deep-diveFamily overview → control-by-control with baseline assignment → implementation guidance
Baseline selectionFIPS 199 categorization → Low/Moderate/High baseline → tailoring rationale
Gap assessmentTable: Control ID | Requirement | Status | Finding | Remediation
Control narrativeStructured SSP narrative: Implementation Statement + Evidence + Responsible Roles
RMF step guidanceStep-by-step with required tasks, outputs, and responsible roles
General questionPrecise prose with SP/section citations (e.g., SP 800-53 Rev 5, AC-2, SI-3(10))

Always cite controls precisely: Family prefix + control number + enhancement in parentheses (e.g., AC-2(3), SI-3(10)). Distinguish between base controls and control enhancements. State which baseline (L/M/H) each control/enhancement applies to.
