Here are some of the highlights we will be working on in Q3: - Agent observability: unified agent graphs, richer tracing (tool‑call span types), built‑in agent evaluations across conversation/response/turn/trajectory. - Evaluation: rule‑based evaluators; LLM‑as‑judge at multiple levels with debugging & cost tracking; comparison dashboards (correlation, confusion matrix, overlap); SDK abstraction for dataset runs. - Data, prompts & platform: multimodal support for Datasets & Playground; I/O schema validation; tool/function support in Prompt Experiments; platform webhooks; in‑app routing. → [View the public roadmap](/docs/roadmap) → [Watch the Town Hall](https://www.youtube.com/watch?v=cz8HqPhDLHE) Recording ## Playground Side-by-Side Comparison ![Playground Side-by-Side Comparison](/images/blog/2025-07-31-langfuse-july-update/multi-playgroundcl.png) Open multiple chat windows in parallel to compare prompts, models, variable inputs, or tools, and restore the test state. This enables faster A/B testing, fewer open tabs, and shorter feedback cycles. → [Learn More](/changelog/2025-07-28-playground-side-by-side) ## Slack & Webhooks for Prompt Changes ![Slack & Webhooks for Prompt Changes](/images/blog/2025-07-31-langfuse-july-update/slack-integrationcl.png) We added Webhooks and a Slack integration to get real-time notifications for new prompt versions, changes to deployment labels or tags, and other edits. We’re expanding webhook triggers to cover more Langfuse events soon. → [Learn More](/changelog/2025-07-30-slack-prompt-notifications) ## Trigger Remote Custom Experiments ![Trigger Remote Custom Experiments](/images/blog/2025-07-31-langfuse-july-update/remote-experimentscl.png) You can now trigger external Dataset Runs directly from the Langfuse UI. This feature enables non-technical users to run tests on Datasets without requiring code changes or manual setup. → [Trigger a remote Dataset Run](/changelog/2025-07-24-remote-experiment-triggers) ## New docs and integration pages ![New docs and integration pages](/images/blog/2025-07-31-langfuse-july-update/new-docs-and-integration-pagescl.png) We reorganized our docs and integration guides to make discovery easier across observability, prompts, and evals. → Explore our new [documentation](/docs) and [integration](/integrations) pages ## More July Releases - [Usage Alerts (Cloud):](/changelog/2025-07-30-usage-alerts) Set a threshold for monthly events; we'll notify you once per billing cycle when you cross it. - [Sessions in the Annotation Queue](/changelog/2025-07-28-sessions-in-annotation-queues): Integrate Sessions into your human annotation workflow. - [n8n Node: Fetch Prompts from Langfuse Prompt Management](/changelog/2025-07-06-n8n-node-for-langfuse-prompts) into your n8n workflow. - Prompt [Full-Text Search](/changelog/2025-07-22-full-text-search-for-prompts): Search through all your prompts to help find and organize large prompt collections. - [LiveKit Integration](/changelog/2025-07-25-livekit-integration): Trace your LiveKit agents to see latencies, costs and use it together with other Langfuse features. --- ## Agent Instructions This page is part of the [Langfuse](https://langfuse.com) documentation, published as plain Markdown for AI agents. Every page is available as Markdown by appending `.md` to its URL, or by sending an `Accept: text/markdown` header.

Ask a specific, self-contained question: ```bash curl -sG "https://langfuse.com/api/search-docs" --data-urlencode "query=How do I trace a LangGraph agent?" ``` - **Index of every page**: , with per-section indexes [llms-docs.txt](https://langfuse.com/llms-docs.txt), [llms-integrations.txt](https://langfuse.com/llms-integrations.txt), and [llms-self-hosting.txt](https://langfuse.com/llms-self-hosting.txt). ### Before writing Langfuse code - **Install the [Langfuse Agent Skill](https://langfuse.com/docs/api-and-data-platform/features/agent-skill).** It encodes Langfuse's own best practices for instrumentation, prompt management, and evaluation, and materially improves results. - **Read [What does a good trace look like?](https://langfuse.com/docs/observability/best-practices.md)** before instrumenting an application. - **Verify endpoints, parameters, and response fields** against the [API reference](https://api.reference.langfuse.com) instead of inferring them from code examples. - **Use the [Langfuse CLI](https://langfuse.com/docs/api-and-data-platform/features/cli)** (`npx langfuse-cli api `) to read or write traces, prompts, datasets, and scores from the terminal.
