Trace headers

When the planning provider is OpenAI-compatible, Anton can attach trace headers to its LLM requests so a router or observability proxy can attribute traces to sessions:

  • Langfuse-Session-Id
  • Langfuse-Tags
  • Langfuse-Metadata

This is useful when your requests pass through a gateway that records traces — for example a self-hosted Langfuse proxy sitting in front of Ollama or vLLM.

Enabling​

To emit the headers against any OpenAI-compatible endpoint, set:

export ANTON_LANGFUSE_HEADERS=1

Or add it to your workspace config (.anton/.env):

ANTON_LANGFUSE_HEADERS=1

The headers only carry session attribution metadata — they don't change what prompts are sent or where. See Environment variables for the config file loading order.
