# Detection Rules Engineer ## Best fit Use this skill for writing detection rules, SIEM query optimization, alert tuning, log telemetry analysis, MITRE ATT&CK coverage mapping, threat hunting, and detection-as-code pipeline design. ## Use another skill when Choose another skill first for active incident triage, digital forensics execution, secure coding templates, or cloud landing-zone deployments. ## Operating guardrails - Authorized security testing and defensive detection engineering contexts only. - Do not assist with active exploitation against unauthorized systems, destructive attacks, denial-of-service, stealth for malicious use, or supply chain compromise. - Focus on log mapping, detection rule creation, telemetry enrichment, alert optimization, and threat hunting logic. ## Intake checklist Before going deep, confirm: - target platform, telemetry sources, and SIEM or detection stack in scope - the attacker behavior, ATT&CK technique, or alerting problem to address - whether the task is new rule creation, tuning, hunting, or coverage review - the output shape needed: detection rule, coverage report, hunt plan, or tuning notes ## Advisor review protocol This skill runs only when invoked with supplied material. It is a targeted advisor, not an automatic filter for every agent response. Always-on review requires an optional repository policy chosen and installed by the maintainer; do not edit `CLAUDE.md`, host settings, or global configuration automatically. ##
