Idiomatic Golang error handling — creation, wrapping with %w, errors.Is/As, errors.Join, custom error types, sentinel errors, panic/recover, the single handling rule, structured logging with slog, HTTP request logging middleware, and samber/oops for production errors. Built to make logs usable at scale with log aggregation 3rd-party tools. Apply when creating, wrapping, inspecting, or logging errors in Go code.
Golang everyday observability — the always-on signals in production. Covers structured logging with slog, Prometheus metrics, OpenTelemetry distributed tracing, continuous profiling with pprof/Pyroscope, server-side RUM event tracking, alerting, and Grafana dashboards. Apply when instrumenting Go services for production monitoring, setting up metrics or alerting, adding OpenTelemetry tracing, correlating logs with traces, migrating legacy loggers (zap/logrus/zerolog) to slog, adding observability to new features, or implementing GDPR/CCPA-compliant tracking with Customer Data Platforms (CDP). Not for temporary deep-dive performance investigation (→ See golang-benchmark and golang-performance skills).
Structured logging extensions for Golang using samber/slog-**** packages — multi-handler pipelines (slog-multi), log sampling (slog-sampling), attribute formatting (slog-formatter), HTTP middleware (slog-fiber, slog-gin, slog-chi, slog-echo), and backend routing (slog-datadog, slog-sentry, slog-loki, slog-syslog, slog-logstash, slog-graylog...). Apply when using or adopting slog, or when the codebase already imports any github.com/samber/slog-* package.
dontbesilent Slow is Fast. It helps entrepreneurs find methods that seem slower but deliver faster results in the long run, and build assets through friction. Trigger methods: /dbs-slowisfast, /slow-is-fast, "Is there a slower way", "Am I going too fast" Slow-is-fast diagnosis. Help entrepreneurs find seemingly slower methods that build assets through friction. Trigger: /dbs-slowisfast, "is there a slower way", "am I going too fast"
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.
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.
Guides users through writing, validating, and operationalizing Non-Functional Requirements (NFRs), Service Level Objectives (SLOs), Service Level Indicators (SLIs), and fitness functions. This skill should be used when a user wants to define or review NFRs for a system, translate NFRs into SLOs/SLIs, or generate automatable fitness functions (performance tests, ArchUnit-style architecture tests, availability checks, recovery drills) that validate a system against its non-functional requirements.
Expert site reliability engineer specializing in SLOs, error budgets, observability, chaos engineering, and toil reduction for production systems at scale.
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.
deslop a diff, remove AI slop and over-engineering while preserving exact behavior. Triggers: /deslop, remove AI slop, clean AI artifacts, strip over-engineered patterns, simplify code, review changes for bloat. Flags: --staged, --unstaged, --base <branch>.
Design Canvas-ready React components with slots and decomposition-first patterns. Use when (1) Designing a component's prop/slot structure, (2) A component is growing too large, (3) Deciding between props vs slots, (4) Refactoring monolithic components. Ensures Canvas compatibility.
Terrain interaction systems for Three.js building games. Use when implementing slope handling, foundation anchoring (Valheim pattern), terrain modification, auto-leveling, or pillar/support generation. Integrates with structural-physics for ground-based stability.
