# CredentialOAuthTool

The coding agent whose subscription an OAuth credential signs in to.

**Kind:** a string enum, used in requests and responses.

## Values

| Value | Description |
|---|---|
| `"Claude"` | Claude Code, on an Anthropic (Claude Pro or Max) subscription. |
| `"Codex"` | Codex, on an OpenAI (ChatGPT) subscription. |

New values can appear, so treat one you don't know as "something else", not as an error.
