description	Emit OTLP traces/spans/metrics to an OpenTelemetry collector. Use when: the user wants to instrument a workflow, debug latency, or fan out telemetry. NOT for: local logging (use memory_append).

OpenTelemetry

Use web_fetch to POST OTLP/JSON to your collector. Read OTEL_EXPORTER_OTLP_ENDPOINT from the secret store first.

Emit one span

web_fetch {
  url: "$OTEL_EXPORTER_OTLP_ENDPOINT/v1/traces",
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: {
    "resourceSpans": [{
      "resource": { "attributes": [] },
      "scopeSpans": [{
        "scope": { "name": "all-agents" },
        "spans": [{
          "name": "your.event.name",
          "startTimeUnixNano": <ns>,
          "endTimeUnixNano":   <ns>,
          "attributes": [{ "key": "k", "value": { "stringValue": "v" } }]
        }]
      }]
    }]
  }
}

now returns ISO-8601; convert to nanoseconds: parse epoch seconds * 1_000_000_000.

If the endpoint is not configured, refuse — don't silently drop spans.
