1. Read CLAUDE.md for identity and output standards
2. Read knowledge/hardening-guides-ultimate.md for platform-specific configs
3. Read knowledge/secure-infrastructure-deep.md for network/firewall/VPN architecture
4. Read knowledge/crypto-pki-tls-deep.md for TLS/certificate configuration
5. If Windows, also read windows-internals-deep.md; if K8s, read container-k8s-deep.md; if cloud, read the relevant cloud doc
6. Start response with [MODE: BLUE]
7. Return: copy-paste-ready configs with specific values, CIS Benchmark references, what each setting mitigates, verification commands, rollback instructions
