# Choose an agent integration

> Pick a built-in Weave integration for your agent SDK or harness and start sending sessions, turns, LLM calls, and tool calls to 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 traces multi-turn agents built with popular SDKs and harnesses without hand-instrumenting each turn. Install a plugin for your agent harness, or call `weave.init()` in code that uses a supported agent SDK, and Weave autopatches the framework. Sessions, turns, LLM calls, and tool calls render in the **Agents** view of your project.

Choose from one of the following supported integrations.

## Agent harnesses

Agent harnesses are end-user agent runtimes, such as coding agents and developer tools. Install the plugin or extension, then start a session in the harness to begin tracing:

* [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. Add `weave.init("[YOUR-TEAM]/[YOUR-PROJECT]")` to your script and Weave autopatches the SDK:

* [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

If your agent isn't built with one of the SDKs above, or it already emits OpenTelemetry spans, use the Weave SDK directly. Weave accepts any OTel span and gives special handling to [GenAI semantic-convention attributes](https://opentelemetry.io/docs/specs/semconv/gen-ai/gen-ai-agent-spans/) so spans render in the **Agents** view:

* [Quickstart: Manually instrument an agent](/weave/custom-agents-quickstart) — a walkthrough of a small multi-turn agent.
* [Trace your agents](/weave/guides/tracking/trace-agents) — the full reference of agent helpers and concepts.

## Next steps

Once your first session reaches Weave, see [View activity in the Agents view](/weave/guides/tracking/view-agent-activity) to explore sessions, turns, and tool calls.
