New in 0.4.0. Prose and code examples to be written. -->\n\n- `ai.experimental_telemetry` is experimental: it may change or be removed.\n\n## Enable telemetry\n\n- Nothing is reported until an adapter is registered or a sink is routed;\n  with telemetry off, spans are no-ops (`id=\"\"`, no clock reads, `push()`\n  does nothing). Check with `is_enabled()`.\n- OpenTelemetry export: perform the standard OpenTelemetry ceremony (tracer\n  provider + OTLP exporter), then\n  `ai.experimental_telemetry.register(otel.OtelAdapter())`. Requires the\n  `ai[otel]` extra.\n- Message content capture is opt-in: `otel.OtelAdapter(capture_content=True)`\n  or `OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT=true`.\n- Call `OtelAdapter.flush()` before a checkpoint and `OtelAdapter.shutdown()`\n  at process exit; the exporter buffers.\n\n## Framework spans\n\n- The framework opens spans automatically: `RunSpanData`, `LoopTurnSpanData`,\n  `AiStreamSpanData`, `AiGenerateSpanData`, `ToolExecutionSpanData`,\n  `HookSpanData`.\n- Dispatch on the type of `span.data` in adapters; span events include\n  `FIRST_TOKEN`, `RESPONSE_COMPLETE`, `HOOK_DEFERRED`, `HOOK_RESOLVED`,\n  `HOOK_CANCELLED`.\n\n## User spans\n\n- `async with span(\"name\") as sp:` — stamps, pushes, nests, and\n  records exceptions automatically.\n- `sp.set_attrs(...)` for attributes; `sp.add_event(name)` for milestones.\n- Typed spans: any Pydantic model with a `kind` field is `SpanData`; open\n  with `span(MyData(...))` and assign `sp.data` fields directly.\n\n## Custom adapters\n\n- Protocol: `on_span_start` \u002F `on_span_event` \u002F `on_span_end` (all required),\n  registered with `register()` — it raises `TypeError` otherwise. Failures\n  are logged and skipped.\n- Prefer the `@adapter` decorator for vendor bridges: one async generator per\n  span, yield loop until `None`, then read `span.data` \u002F `span.error`. Also\n  works on a class whose `__call__` is an async generator method, for\n  adapters with configuration or state.\n- Subclass `OtelAdapter` and override `span_name()` \u002F `span_attrs()`\n  to adjust OpenTelemetry output.\n\n## Durable and serverless execution\n\n- Inside a workflow body, route spans to a sink instead of the adapters and\n  keep delivery in steps; with deterministic clock and random installed,\n  agent runs and the `span()` context manager work in the body. Use the\n  low-level API for spans that cross process boundaries.\n- Collect in the body: `sink = DictSink()`, run under\n  `async with use_sink(sink):`, then serialize `sink.finished_spans` with\n  `model_dump(mode=\"json\")`.\n- Deliver from a step: `await push_all(payload)`.\n- Manual lifecycle: `create_span()` then `stamp_start()` \u002F `stamp_end()` \u002F\n  `push()`; nothing is reported except by pushing.\n- Continue a trace across processes: restore with `Span.model_validate(...)`,\n  parent under it with `async with use_span(restored):` or\n  `span(..., parent=restored)`.\n- Deterministic timestamps: `use_time(workflow.time_ns)`; read the ambient\n  clock with `now_ns()`.\n- `use_sink`, `use_span`, and `use_time` are async context managers; they also\n  work as decorators on async functions, but never with a plain `with`.\n- Errors serialize as `SpanError` (`SpanError.from_exception(exc)`), so spans\n  that failed in another process still report.\n",{"data":37,"body":40},{"name":4,"description":6,"metadata":38},{"sdk-version":39},"0.4.0",{"type":41,"children":42},"root",[43,50,67,74,168,174,274,280,350,356,474,480],{"type":44,"tag":45,"props":46,"children":47},"element","h1",{"id":4},[48],{"type":49,"value":4},"text",{"type":44,"tag":51,"props":52,"children":53},"ul",{},[54],{"type":44,"tag":55,"props":56,"children":57},"li",{},[58,65],{"type":44,"tag":59,"props":60,"children":62},"code",{"className":61},[],[63],{"type":49,"value":64},"ai.experimental_telemetry",{"type":49,"value":66}," is experimental: it may change or be removed.",{"type":44,"tag":68,"props":69,"children":71},"h2",{"id":70},"enable-telemetry",[72],{"type":49,"value":73},"Enable telemetry",{"type":44,"tag":51,"props":75,"children":76},{},[77,106,127,147],{"type":44,"tag":55,"props":78,"children":79},{},[80,82,88,90,96,98,104],{"type":49,"value":81},"Nothing is reported until an adapter is registered or a sink is routed;\nwith telemetry off, spans are no-ops (",{"type":44,"tag":59,"props":83,"children":85},{"className":84},[],[86],{"type":49,"value":87},"id=\"\"",{"type":49,"value":89},", no clock reads, ",{"type":44,"tag":59,"props":91,"children":93},{"className":92},[],[94],{"type":49,"value":95},"push()",{"type":49,"value":97},"\ndoes nothing).
