Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# OpenTelemetry in Ruby Entry point for OpenTelemetry mechanics in Ruby applications. Load only the reference that matches the task; each reference is self-contained. ## References | File | Use when | |---|---| | [`references/setup.md`](references/setup.md) | Installing gems, configuring `OpenTelemetry::SDK.configure`, selecting OTLP exporters, setting resources and environment variables, and handling process shutdown. | | [`references/api.md`](references/api.md) | Writing manual traces, metrics, or logs; managing context and propagation; testing emitted telemetry. | | [`references/instrumentation-libraries.md`](references/instrumentation-libraries.md) | Selecting and configuring contrib instrumentation for Rails, Rack, Sinatra, HTTP clients, databases, jobs, messaging, and other gems. | | [`references/performance.md`](references/performance.md) | Tuning sampling, batching, cardinality, forked-process behavior, exporters, and lifecycle handling. | | [`references/breaking-changes.md`](references/breaking-changes.md) | Reviewing Ruby/runtime compatibility, independently versioned gems, experimental signal changes, and core/contrib upgrades. | ## Signal stability matters …

How to install
mdr add ollygarden/opentelemetry-agent-skills/otel-ruby@sha256:2160727118c501d2The line at the top of this page pins the label git:20261026.be344f2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
