DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Chrome sessions get nudged to batch browser actions

Chrome & Browser

In Chrome, single tool calls prompt a nudge to batch browser actions instead.

browser_batch
What

In Claude in Chrome, a turn that made a single tool call now draws a reminder to combine clicks, typing, navigation and screenshots into one browser_batch call because it is significantly faster.

Details
  • The nudge is keyed to the claude-in-chrome surface and fires only after a one-tool-call turn.
Evidence

Prefer browser_batch to execute multiple actions in one call

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
