otel-instrument
OpenTelemetry orchestrator — auto-activates on observability, telemetry, tracing, metrics, logging, OTel SDK, Collector, semantic conventions, or OTTL requests. Routes to the correct sub-skill.
otel-collector
OpenTelemetry Collector configuration — receivers, processors, exporters, pipelines, sampling, deployment. Covers OTLP, Prometheus, filelog, hostmetrics; processor ordering; pipeline design; head/tail sampling; and RED metric derivation via signaltometrics.
feature-flags
How to add a new feature flag using the ResourceRegistry gem. Activate when adding, modifying, or checking feature flags, or when implementing new features (which should always be placed behind a feature flag).
fullstory-logging
Core concepts for Fullstory's Logging API. Platform-agnostic guide covering log levels, message formatting, privacy considerations, and best practices. See SKILL-WEB.md and SKILL-MOBILE.md for implementation examples.
grafana-billing
Query Prometheus and Loki billing metrics from Grafana. Use when discussing observability costs, active series, ingestion rates, storage usage, or cardinality analysis.
log-analysis
Analyze application logs to identify errors, performance issues, and security anomalies. Use when debugging issues, monitoring system health, or investigating incidents. Handles various log formats including Apache, Nginx, application logs, and JSON logs.
logging-observability
Guidelines for structured logging, distributed tracing, and debugging patterns across languages. Covers logging best practices, observability, security considerations, and performance analysis.
config-reader
Read and manage daplug configuration from CLAUDE.md using <daplug_config> blocks, with legacy fallback and migration support.
issue-logging-during-ralph-execution
Provides guidance for systematically logging issues during Ralph autonomous execution. Use when: (1) Any problem occurs during task execution, (2) Manual intervention is required, (3) Workflows don't work as expected, (4) Quality gates fail or require workarounds.
codereview-observability
Review logging, metrics, tracing, and alerting. Ensures systems are observable, debuggable, and operable. Use when reviewing code that adds logging, metrics, or monitoring.
observability
This skill should be used when the user asks about "Effect logging", "Effect.log", "Effect metrics", "Effect tracing", "spans", "telemetry", "Metric.counter", "Metric.gauge", "Metric.histogram", "OpenTelemetry", "structured logging", "log levels", "Effect.logDebug", "Effect.logInfo", "Effect.logWarning", "Effect.logError", or needs to understand how Effect handles logging, metrics, and distributed tracing.
datetime-pickers
Use ThemedDateTimePicker, ThemedDateTimeRangePicker, or ThemedDateTimeSteppedPicker in a layrz Flutter widget. Apply when adding a combined date-and-time selection field.
date-pickers
Use ThemedDatePicker, ThemedDateRangePicker, ThemedMonthPicker, or ThemedMonthRangePicker in a layrz Flutter widget. Apply when adding a date or month selection field.
fullstory-component-wellbeing
Expert guidance for monitoring frontend component health, performance, and rendering stability within Fullstory. Framework-agnostic patterns for React, Vue, Angular, Svelte, and React Native.
workleap-telemetry
Guide for @workleap/telemetry, Workleap's unified telemetry connecting Honeycomb, LogRocket, and Mixpanel with automatic correlation IDs. Use this skill when: (1) Initializing wl-telemetry in a frontend application (2) Correlation values (Telemetry Id, Device Id) and cross-tool data correlation (3) Honeycomb tracing, OpenTelemetry spans, and performance monitoring (4) LogRocket session replay, user identification, and privacy controls (5) Mixpanel analytics, event tracking, and cross-product tracking (6) Configuring wl-telemetry diagnostic loggers (LogRocketLogger) (7) Storybook/test setup with Noop telemetry clients (8) Reviewing or troubleshooting telemetry instrumentation
monitoring-operations
Use when setting up metrics, alarms, or troubleshooting missing data in OCI Monitoring. Covers metric namespace confusion, alarm threshold gotchas, log collection setup, and common monitoring gaps.
grafana
Grafana Dashboard-Entwicklung und Metric-Queries. Nutzt den offiziellen Grafana MCP Server um Dashboards direkt in Grafana Cloud zu erstellen, zu lesen und zu aktualisieren sowie PromQL-Queries abzusetzen. Verwenden wenn der Operator "Grafana", "Dashboard", "Panel", "Metrik abfragen", "Alert Rule", "grafana bauen" oder "/grafana" sagt.
extensions-logging
Guidance for Microsoft.Extensions.Logging and LoggerMessage source generators. USE FOR: ILogger abstraction, LoggerMessage source-generated logging, structured logging with event IDs, log filtering and configuration, high-performance logging patterns. DO NOT USE FOR: Serilog-specific sinks and enrichers (use serilog), NLog-specific targets and routing (use nlog), OpenTelemetry log export (use otlp-logging).
otlp-logging
Guidance for OpenTelemetry Protocol (OTLP) logging and observability in .NET. USE FOR: OTLP log export, OpenTelemetry traces and metrics, distributed tracing with Activity API, configuring OTel collectors, correlating logs with traces, custom metrics and instruments. DO NOT USE FOR: Serilog-specific sinks and enrichers (use serilog), NLog-specific targets and routing (use nlog), Microsoft.Extensions.Logging abstractions (use extensions-logging).
