Wrap the top-level function with `@observe`, set trace-level fields with `update_current_trace(...)`, and wrap inner functions you want to grade with `@observe` too. Attach a component metric by passing `metrics=[...]` to `@observe` and registering its test case with `update_current_span(test_case=...)`:

Build your agent with `create_agent`, then pass `deepeval`'s `CallbackHandler` to its `invoke` / `ainvoke` method inside the loop.

`next_llm_span` is one-shot — only the first LLM span in the agent run picks up the metric, so later turns inside `create_agent`'s loop won't be scored. To score every LLM call, drive the loop yourself (`next_llm_span` per `agent.invoke(...)`) or score end-to-end with trace-level metrics on `CallbackHandler(metrics=[...])`. For retrievers, use `next_retriever_span(...)` the same way; for deterministic tool calls, prefer `next_tool_span(...)` + `update_current_span(...)`. See the [LangChain integration](/integrations/frameworks/langchain) for the full surface.

Wire your `StateGraph`, then pass `deepeval`'s `CallbackHandler` to its `invoke` / `ainvoke` method inside the loop. Stage a component metric for the next LLM call with `next_llm_span(...)` — the `CallbackHandler` drains it onto the first LLM span LangGraph opens during the graph run:

Call `instrument_crewai()` once, then build your crew with `deepeval`'s `Crew`, `Agent`, `LLM`, and `@tool` shims. Attach component metrics directly on `Agent` (agent span), `LLM` (LLM span), or `@tool` (tool span):
