Build custom OpenTelemetry Collector distributions with OCB (OpenTelemetry Collector Builder). Use when authoring or debugging a builder manifest (builder.yaml), choosing component and provider versions, building a collector that bundles a custom or out-of-distribution component, setting up CI or Docker builds of a distribution, or troubleshooting OCB build failures. Triggers on "ocb", "collector builder", "custom collector distribution", "builder manifest", "builder-config", and…
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 Collector Builder (OCB) OCB generates and compiles a custom Collector binary from a YAML manifest that lists exactly the components to include. Source of truth: [cmd/builder](https://github.com/open-telemetry/opentelemetry-collector/tree/main/cmd/builder) in opentelemetry-collector. Use OCB when the stock `otelcol`/`otelcol-contrib` distributions don't fit: you need a component that ships in no distribution, a private/local component, or a slimmer binary with only the components you run. This skill covers building the distribution. For configuring individual components, see `otel-collector`; for writing a new component, see the component-authoring guidance; for generating test traffic against the built binary, see `otel-telemetrygen`. ## Workflow 1. **Install OCB** at the version matching your target Collector version (see [Install](#install)). 2. **Write the manifest** — `dist:` block plus component lists. Start from the [minimal manifest](#minimal-manifest); full key reference in [references/manifest.md](references/manifest.md). …

How to install
mdr add ollygarden/opentelemetry-agent-skills/otel-collector-builder@sha256:750cbc29ae6933c0The line at the top of this page pins the label git:20261026.7dc08b2, 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.
