MUST USE when investigating performance issues on a ClickHouse-managed Postgres instance. Provides an evidence-based RCA workflow that scrapes the Prometheus endpoint for system signal, pulls per-digest evidence from the Slow Query Patterns API, and recommends (does not apply) a fix.
Use when building interactive components for predefined slots in Wix business solutions. Triggers include site plugin, slot, Wix app integration, plugin explorer, business solution extension.
Build production-ready monitoring, logging, and tracing systems. Implements comprehensive observability strategies, SLI/SLO management, and incident response workflows. Use PROACTIVELY for monitoring infrastructure, performance optimization, or production reliability.
Implement comprehensive observability for service meshes including distributed tracing, metrics, and visualization. Use when setting up mesh monitoring, debugging latency issues, or implementing SLOs for service communication.
Use when defining SLIs/SLOs, managing error budgets, or building reliable systems at scale. Invoke for incident management, chaos engineering, toil reduction, capacity planning.
Query Google Calendar free/busy status for multiple users to find a meeting slot.
Instrumenting Go applications with OpenTelemetry for distributed tracing, Prometheus for metrics, and structured logging with slog
Communicate ideas and information to others with purpose, clarity, and integrity. Ensure that artifacts are structured and phrased in a way that is mindful of their audience while avoiding AI slop patterns. Use when the user requests assistance with writing, commentary, or communication; when they point out AI slop, when they ask things like "help me say", "write for [a specific audience or context]", "polish [comments, sentences, artifacts]", or the like.
Monitoring guidelines for applications and infrastructure including metrics collection, alerting strategies, and SLO-based monitoring
SQL optimization best practices for OceanBase database (MySQL & Oracle modes). Covers query optimization, index usage, execution plan analysis, slow query tuning, and performance optimization techniques. Activates for SQL optimization, query performance, index design, execution plan, slow query, database performance.
Expertise in Senior Principal Engineering refactoring. Use when you need to eliminate technical debt, remove "AI Slop," simplify complex logic, and ensure DRY code.
When validating system performance under load, identifying bottlenecks through profiling, or optimizing application responsiveness. Covers load testing (k6, Locust), profiling (CPU, memory, I/O), and optimization strategies (caching, query optimization, Core Web Vitals). Use for capacity planning, regression detection, and establishing performance SLOs.
