What problem does it solve?

Cloudflare Workers often lack built-in observability. This Skill provides wrappers around a Worker's fetch handler to emit OTLP traces, metrics, and logs and to send error events via utels without changing your business logic.

Core Features & Use Cases

• Lightweight wrappers: withTelemetry and withUtelsErrorTracking integrate with OTLP backends and utels project to collect traces, metrics, logs, and exception events.
• Non-intrusive instrumentation: wraps D1 query telemetry and related bindings to surface slow queries and performance data without modifying application code.
• Use Case: you stand up a new Worker and want end-to-end visibility from request to response, with automated error reporting.

Quick Start

Wrap your worker's fetch handler with withTelemetry and withUtelsErrorTracking to enable OTLP telemetry and optional utels error tracking with minimal code changes.
