Skill UI

This skill provides comprehensive testing for WebSocket APIs, covering protocol basics, Cross-Site WebSocket Hijacking (CSWSH), and common security flaws. Use it when testing applications that rely on real-time communication, chat features, or persistent data streams. It validates Origin checks, session binding, and message integrity.

This skill enforces disciplined SLO definition based on SRE principles, ensuring that reliability promises are measurable and actionable. It guides users in selecting the right SLI (Service Level Indicator), accurately calculating error budgets, setting multi-window burn-rate alerts, and reviewing existing SLO documents for common architectural flaws (e.g., targets too aggressive, wrong SLI selection). Ideal for defining, reviewing, and maintaining service reliability commitments.
