How does this skill help with OpenTelemetry?

It provides specific patterns and mental models for span annotations, helping you determine which attributes to attach to OTel spans to ensure they are useful for future debugging.

What are wide events in observability?

Wide events, or canonical log lines, are single, comprehensive records containing all relevant context—such as user identity, business state, and technical performance—for an operation, optimized for querying rather than just writing.

What is the benefit of high dimensionality?

High dimensionality allows you to add numerous fields to a single event. This enables you to 'slice and dice' your data by any attribute, such as account tier or feature flags, to find specific patterns during an incident.

When should I use the wide-events skill?

Use it when planning new service instrumentation, reviewing code for telemetry coverage, or when you find yourself unable to answer specific questions during a production incident.

分析と監視

Guides the implementation of high-dimensionality instrumentation and canonical log lines for superior system observability.

概要

This skill provides a conceptual framework and implementation strategy for 'wide events'—comprehensive, structured records that capture full context (business, user, technical, and outcome) within a single span. It helps Claude assist developers in moving away from scattered, low-context logging toward a query-optimized observability strategy using OpenTelemetry. It is particularly useful when designing instrumentation schemas, reviewing span annotations, or debugging complex production incidents where traditional logs fail to provide the necessary context for root cause analysis.
