# Claude Code with Oz

Run Claude Code with Oz. Strong at code review, deep bug investigation, large feature planning, and frontend or UI work.

Claude Code is Anthropic’s agentic coding tool. Running it with Oz puts Claude Code inside a Warp-managed environment and connects it to the rest of the Oz platform — triggers, environments, secrets, observability, and governance — while still behaving like the Claude Code your team already uses.

Note

This page covers Claude Code as a **cloud** harness, dispatched and orchestrated by Oz. To run Claude Code locally in your Warp terminal, see [Claude Code in Warp](/agent-platform/cli-agents/claude-code/) instead.

## Key features

-   **Cloud orchestration** - Launch Claude Code from any Oz trigger: the Warp app, the Oz web app, the Oz CLI, the REST API, schedules, Slack mentions, Linear issues, or GitHub Actions.
-   **Claude model picker** - Choose the Claude model the harness uses, including the latest pinned Opus, Sonnet, and Haiku releases, the `best`/`opus`/`sonnet`/`haiku` aliases, and 1M-context variants.
-   **First-class subagent** - A Warp Agent parent can dispatch Claude Code subagents to handle code-review-heavy or judgment-heavy steps within a larger orchestration.

## Available models

The Claude Code harness exposes Anthropic’s coding-tuned model lineup. Common picks:

-   `best` - Resolves to the current top-of-line Claude model.
-   `opus`, `sonnet`, `haiku` - Aliases that resolve to the current default for that family.

For the full list — including 1M-context variants for very large codebases and planning-tuned models — open the model picker in the Warp app’s Cloud Mode or the **Model** field on the Oz web app’s new-run pane.

## Credentials and billing

Claude Code calls Anthropic directly using credentials your team provides. Oz supports three Anthropic credential types, stored as [Warp-managed secrets](/agent-platform/cloud-agents/secrets/):

-   **Anthropic API key** - For direct Anthropic API access.
-   **Anthropic Bedrock API key** - For Bedrock-routed inference using an API key.
-   **Anthropic Bedrock access key** - For Bedrock-routed inference using AWS access credentials.

Anthropic bills your account directly for inference. Warp still meters [compute credits](/support-and-community/plans-and-billing/credits/#compute-credits) for the run’s sandbox and [platform credits](/support-and-community/plans-and-billing/platform-credits/) for the orchestration layer.

For setup steps, see [Connecting Claude Code credentials](/agent-platform/cloud-agents/harnesses/authentication/#connecting-claude-code-credentials).

## Starting a Claude Code run

-   **Warp app** - In Cloud Mode, click the **Agent harness** dropdown above the input and choose **Claude Code**.
-   **Oz web app** - On the new run or new schedule pane, choose **Claude Code** in the **Harness** field. A **Claude Code auth secret** field appears below it; pick one of your stored Anthropic secrets.
-   **API and SDK** - Set the agent config `harness` to `claude` and the Anthropic secret name on the matching auth-secret field. See the [API reference](/reference/api-and-sdk/).
