uselemma-tracing 1.0.0

OpenTelemetry-based tracing module for Lemma

uselemma-tracing

OpenTelemetry-based tracing for AI agents. Capture inputs, outputs, timing, token usage, and errors — then view everything in Lemma.

Installation

pip install uselemma-tracing

Quick Start

1. Register the tracer provider

Call register_otel once when your application starts. It reads LEMMA_API_KEY and LEMMA_PROJECT_ID from environment variables by default.

from uselemma_tracing import register_otel

register_otel()

2. Wrap your agent

wrap_agent creates an OpenTelemetry span around your agent function and provides helpers for recording results.

from uselemma_tracing import wrap_agent

def my_agent(ctx, user_message: str):
    result = do_work(user_message)
    ctx.record_generation_results({"response": result})
    return result

wrapped = wrap_agent("my-agent", my_agent, initial_state={"user_message": user_message})
result, run_id, span = wrapped()

Environment Variables

Variable	Description
LEMMA_API_KEY	Your Lemma API key
LEMMA_PROJECT_ID	Your Lemma project ID

Both are required unless passed explicitly to register_otel().
