otel-cpp

What problem does it solve?

It helps you correctly add or repair OpenTelemetry (OTel) SDK setup and instrumentation in a verified native C++ codebase so traces, metrics, and logs are consistent and useful in Tsuga.

Core Features & Use Cases

• C++ OTel setup guidance: configure CMake dependencies, SDK initialization, shutdown/flush, and exporter wiring for OTLP over HTTP or gRPC.
• Instrumentation correctness guardrails: correct span kinds, status handling, lifecycle management (including span->End() and scope usage), and context propagation requirements.
• Signal-specific instrumentation patterns: traces, metrics (including Synchronous Gauge), logs (trace-log correlation), and async messaging patterns using MapCarrier and span Links for Kafka/AMQP/SQS.
• Production-ready anti-pattern prevention: catch common mistakes such as missing global propagator setup, incorrect endpoints, broken shutdown, wrong parent/child relationships for messaging, and span/resource attribute errors.
• Verification workflow: post-deploy smoke testing to confirm that telemetry signals actually arrive.

Quick Start

Use the otel-cpp skill when your confirmed C++ service needs OTel SDK setup or an instrumentation fix, and ask it to propose the minimal patch and route required changes through the mutation gate.
