15761576| [Batch processing](https://platform.claude.com/docs/en/build-with-claude/batch-processing) | Supported. `usage.iterations` is reported per item. |
1577| [Token counting](https://platform.claude.com/docs/en/build-with-claude/token-counting) | Returns the executor's first-iteration input tokens only. For a rough advisor estimate, call `count_tokens` with `model` set to the advisor model and the same messages. |
1577| [Token counting](https://platform.claude.com/docs/en/build-with-claude/token-counting) | Returns the executor's first-iteration input tokens only. For a rough advisor estimate, call `client.beta.messages.count_tokens()` (python, ruby; typescript: `client.beta.messages.countTokens()`; go, csharp: `client.Beta.Messages.CountTokens()`; java: `client.beta().messages().countTokens()`; php: `$client->beta->messages->countTokens()`; cli: `ant beta:messages count-tokens`; curl: `POST /v1/messages/count_tokens`) with `model` set to the advisor model and the same messages. |
15781578| [Context editing](https://platform.claude.com/docs/en/build-with-claude/context-editing) | `clear_tool_uses` is not fully compatible with advisor tool blocks. With `clear_thinking`, see the earlier caching warning. |
15791579| `pause_turn` | A dangling advisor call ends the response with `stop_reason: "pause_turn"` and a `server_tool_use` block with no result when no client `tool_use` block is awaiting your result in the same turn. The advisor runs on resumption. If the executor also called one of your tools in that turn, the response ends with `stop_reason: "tool_use"` instead, and the pending advisor call runs at the start of your next request, after you send the `tool_result` blocks. See [Resuming a paused turn](https://platform.claude.com/docs/en/agents-and-tools/tool-use/advisor-tool#resuming-a-paused-turn), [Mixing server tools and client tools in one turn](https://platform.claude.com/docs/en/agents-and-tools/tool-use/server-tools#mixing-server-tools-and-client-tools-in-one-turn), and [Server tools](https://platform.claude.com/docs/en/agents-and-tools/tool-use/server-tools#the-server-side-loop-and-pause-turn). |
