15571558| A `browser_state` block that breaks a rule in [Track tabs with `browser_state`](https://platform.claude.com/docs/en/agents-and-tools/tool-use/browser-use-tool#track-tabs-and-page-state), for example, one on an `is_error: true` result or on a result that doesn’t answer a browser member call, more than one in a result, a non-empty `tabs` without exactly one `active: true` entry, a duplicate `tab_id`, an empty `state_changes` array, a `tab_opened` whose `tab_id` isn’t in `tabs`, two state changes for one `download_id` or a state-change field its `type` doesn’t declare ([Report downloads](https://platform.claude.com/docs/en/agents-and-tools/tool-use/browser-use-tool#report-downloads)), or a field over its limits | Fix the block. “Nothing to report” is expressed by omitting the block or the `state_changes` field, never by an empty value. |
15581559| A successful `new_tab`, `switch_tab`, `close_tab`, or `list_tabs` result whose `content` isn’t exactly one `browser_state` block, or a `new_tab` result without exactly one `tab_opened` matching the active tab | The API renders these results from the block and needs it in that exact shape; see [Tab management results](https://platform.claude.com/docs/en/agents-and-tools/tool-use/browser-use-tool#tab-management-results). |
15591560| An `image` in a result over your model’s [image size limits](https://platform.claude.com/docs/en/build-with-claude/vision#evaluate-image-size), or over the stricter per-image limit that applies once the request holds [more than 20 images](https://platform.claude.com/docs/en/build-with-claude/vision#request-limits), counting screenshots and `zoom` images in earlier results | The API doesn’t downscale toolset images. Resize screenshots before returning them ([Size screenshots to fit image limits](https://platform.claude.com/docs/en/agents-and-tools/tool-use/computer-use-tool#handle-coordinate-scaling-for-higher-resolutions)). |
1560| A `model` that doesn’t support `browser_toolset_20260801` | See [Compatibility](https://platform.claude.com/docs/en/agents-and-tools/tool-use/browser-use-tool#compatibility) for the supported models. |
