opentelemetry-ottl

OpenTelemetry Transformation Language (OTTL) for OTel Collector pipelines. Use when writing or debugging OTTL statements in the transform processor, filter processor, or routing connector in any collector configuration — context selection, path expression mistakes (`attributes` vs `resource.attributes`), `error_mode`, cardinality reduction with `keep_keys`, JSON body handling with `ParseJSON`, PII redaction with `SHA256` / `replace_pattern`, and span naming. Not for receiver/exporter connectivity, DNS, pipeline wiring, or telemetry that never reaches the processor — those are infra problems, not OTTL problems.

opentelemetry-collector

OpenTelemetry Collector deployment, configuration, and troubleshooting for Coralogix users. Use when writing or debugging collector configs — the `coralogix` exporter (`domain:` vs `endpoint:`, `${env:CORALOGIX_PRIVATE_KEY}` bracket syntax, `coralogix/resource_catalog` variant), the universal processor chain, agent → cluster-collector → gateway topology, spanmetrics/tail_sampling/k8sattributes placement, and Coralogix-specific presets. Covers the `otel-integration` Helm chart (EKS/GKE/AKS/ OpenShift, GKE Autopilot Warden, EKS Fargate), ECS EC2 daemonset, ECS Fargate sidecar, Linux/Windows/macOS standalone, Docker, and the universal installer. Not for OTTL authoring (use the `opentelemetry-ottl` skill) or OpAMP supervisor/Fleet Manager internals beyond the config-precedence callout.

opentelemetry-instrumentation

Instruments Java, Python, Node.js, .NET, and Go applications with OpenTelemetry SDKs to send traces, metrics, and logs to Coralogix. Use for SDK-side OTel setup, OTLP exporter env vars, Coralogix resource attributes, APM transaction samplers, Kubernetes Operator injection, or debugging missing traces, metrics, logs, or no telemetry from an application. Not for OTel Collector config (use opentelemetry-collector), OTTL authoring (use opentelemetry-ottl), eBPF instrumentation, or Lambda layers.
