Out‑of‑the‑box (no annotations required)

  • LangChain (Py/JS) — OpenAI calls + HTTP/tooling captured via OTEL
  • LlamaIndex (Py) — OpenAI spans via OTEL
  • CrewAI / smolagents / LangGraph — captured at the API/tool layer via OTEL
If your framework is not listed, raw spans still work. You can add semantic steps later.

​
Optional: annotated steps (Traceloop/OpenLLMetry)

Use decorators/annotations to mark workflow/task/agent/tool steps. Example (Python): 
from openllmetry.decorators import workflow, task

@workflow(name="research_bridge_time")
def run():
    lookup_speed()
    lookup_length()

@task()
def lookup_speed():
    ...

​
If your framework isn’t supported

  • Keep OTEL on → Brixo infers steps from timing, parent/child links, tools/models.
  • Optionally wrap only top‑level functions with annotations for stable labels.
