# Trace agent integrations

> Connect W&B Weave to agent SDKs, agent harnesses, and custom agents so sessions appear in the Agents view.

<Note>
  Weave for Agents is in public preview. Features, APIs, and the Agents view UI may change before general availability.
</Note>

W\&B Weave can trace multi-turn agentic applications without hand-instrumenting every turn. For supported agent SDKs and harnesses, call `weave.init()` and Weave autopatches the framework. Sessions, turns, LLM calls, and tool calls are captured automatically and rendered in the **Agents** view.

## Agent harnesses

Agent harnesses are end-user agent runtimes (such as coding agents and developer tools) that produce spans Weave can capture. Install the appropriate plugin or extension and your harness sessions are routed to the **Agents** view:

* **[Claude Code plugin](/weave/guides/integrations/agents/claude-code-harness)**
* **[Codex plugin](/weave/guides/integrations/agents/codex-harness)**
* **[OpenClaw plugin](/weave/guides/integrations/agents/openclaw-harness)**
* **[Pi extension](/weave/guides/integrations/agents/pi-dev-harness)**

## Agent SDKs

Agent SDKs are libraries for building agents and multi-agent workflows in your own application code. Weave autopatches the following SDKs:

* **[OpenAI Agents SDK](/weave/guides/integrations/agents/openai-agents-sdk)**
* **[Google Agent Development Kit (ADK)](/weave/guides/integrations/agents/google-adk)**
* **[Claude Agent SDK](/weave/guides/integrations/agents/claude-agents-sdk)**

## Custom agents and OpenTelemetry

Use the Weave SDK directly to instrument custom agents, including any agent that emits OpenTelemetry spans. Weave accepts any OTel span and has special handling for [GenAI semantic-convention attributes](https://opentelemetry.io/docs/specs/semconv/gen-ai/gen-ai-agent-spans/) so your spans render correctly in the **Agents** view.

To learn how to instrument custom agents with the Weave SDK directly, see [Trace your agents](/weave/guides/tracking/trace-agents), or the [Trace an agent quickstart](/weave/agents-quickstart) for a walkthrough.
