 - `otel.captureContent`: opt-in raw content capture for OTEL span attributes. Defaults to off. Boolean `true` captures non-system message/tool content; the object form lets you enable `inputMessages`, `outputMessages`, `toolInputs`, `toolOutputs`, and `systemPrompt` explicitly.
+- `OPENCLAW_OTEL_PRELOADED=1`: environment toggle for hosts that already registered a global OpenTelemetry SDK. OpenClaw then skips plugin-owned SDK startup/shutdown while keeping diagnostic listeners active.
 - `cacheTrace.enabled`: log cache trace snapshots for embedded runs (default: `false`).
 - `cacheTrace.filePath`: output path for cache trace JSONL (default: `$OPENCLAW_STATE_DIR/logs/cache-trace.jsonl`).
 - `cacheTrace.includeMessages` / `includePrompt` / `includeSystem`: control what is included in cache trace output (all default: `true`).
