+
+# Observability with Laminar
+
+This tutorial covers how to integrate goose with Laminar to trace your goose sessions and understand how the agent is performing.
+
+## What is Laminar
+
+[Laminar](https://laminar.sh/) is an open-source observability platform purpose-built for AI agents. It traces LLM calls, tool execution, and custom functions so you can debug, evaluate, and improve agent behavior.
+
+## Why Laminar for goose
+
+- High-signal traces for LLM calls, tools, and sub-agents.
+- Replay any span in the Playground to compare prompts and models.
+- Build datasets from production traces and run evaluations.
+- Analyze trace patterns with natural language queries and dashboards.
+
+## Set up Laminar
+
+Sign up for Laminar Cloud at [laminar.sh](https://laminar.sh) or self-host Laminar from the [open-source repo](https://github.com/lmnr-ai/lmnr). Grab your project API key.
+
+## Configure goose to export OTLP to Laminar
+
+goose exports OpenTelemetry data over OTLP/HTTP. Point the exporter to Laminar and provide your API key as an authorization header.
+
+### Laminar Cloud
+
+```bash
+export LMNR_PROJECT_API_KEY=lmnr_proj_...
+export OTEL_EXPORTER_OTLP_ENDPOINT="https://api.lmnr.ai"
+export OTEL_EXPORTER_OTLP_HEADERS="authorization=Bearer ${LMNR_PROJECT_API_KEY}"
+export OTEL_EXPORTER_OTLP_TIMEOUT=10000
+```
+
+### Self-hosted Laminar
+
+```bash
+export LMNR_PROJECT_API_KEY=lmnr_proj_...
+export OTEL_EXPORTER_OTLP_ENDPOINT="http://localhost:8000"
+export OTEL_EXPORTER_OTLP_HEADERS="authorization=Bearer ${LMNR_PROJECT_API_KEY}"
+```
+
+If your self-hosted instance does not require auth, you can omit `OTEL_EXPORTER_OTLP_HEADERS`.
+
+:::tip
+If you do not see traces, try setting the endpoint to the explicit OTLP path, such as `https://api.lmnr.ai/v1/traces` or `http://localhost:8000/v1/traces`.
+:::
+
+## Run goose with Laminar enabled
+
+Start goose normally. With the OTLP environment variables set, Laminar will capture traces of your goose sessions and tool execution.
