Summary

Adds a new integration page documenting how to enable Langfuse observability tracing for the Hermes Agent framework by Nous Research.

Hermes ships a bundled Langfuse plugin (plugins/observability/langfuse) that is opt-in and hooks into Hermes lifecycle events to trace conversation turns, LLM calls, and tool usage automatically.

Changes

  • cookbook/integration_hermes.ipynb — New integration notebook covering:

    • Install dependencies (hermes-agent, langfuse)
    • Environment variable setup (standard LANGFUSE_* vars, with note about HERMES_LANGFUSE_* prefixed variants)
    • Langfuse client auth check
    • Enabling the bundled plugin via hermes plugins enable observability/langfuse
    • What gets traced (conversation turns, LLM generations, tool calls, token usage/cost)
    • Optional tuning variables (HERMES_LANGFUSE_ENV, HERMES_LANGFUSE_SAMPLE_RATE, etc.)
    • View traces step
  • cookbook/_routes.json — New route entry: integrations/frameworks/hermes

  • public/images/integrations/hermes_icon.png — Logo fetched from nousresearch.com

Integration details

Remaining TODOs

  • Replace trace screenshot placeholder (hermes-example-trace.png) with an actual screenshot
  • Replace example trace URL placeholder with a real public trace link
  • Consider replacing the NousResearch apple-touch-icon with a Hermes-specific SVG logo if one becomes available
  • Run bash scripts/update_cookbook_docs.sh to generate the MDX output
