What
The screenshot and zoom actions in the Claude in Chrome browser tool now accept a scale parameter. Setting it to 0.5 returns a quarter-size image, which reduces the number of tokens the image consumes.

Added since
A small documentation edit on whats-new-fable-5-1 touched a line naming scale after this was published.
* **Billing:** a refusal that arrives before any output is billed when it's in a category with low volumes of false positives, to disrupt attempts to circumvent Anthropic's safeguards at scale ([How refusals are billed](https://platform.cl…models/fable-5-1/whats-new-fable-5-1 see the edit
Confirmed since
Anthropic's documentation has since written up scale, on Keep Claude working toward a goal.
To change the first interval, set [`CLAUDE_CODE_GOAL_CHECKIN_MINUTES`](/docs/en/env-vars). Claude Code uses your value in place of the 30-minute interval and scales the later intervals with it. Set it to `0` to turn off check-ins and [auto…goal see the edit
