Source Intelligence

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.

Window-activation clicks reset the double-click counter

Terminal Input

A click that only refocuses the window no longer counts toward a double-click.

What

A press classified as merely re-focusing the terminal window now sets the click count back to zero rather than accumulating toward a double-click, and stale partial mouse sequences are discarded on a 2000 ms timer. Unconditional input-layer behaviour.

Evidence

MOUSE_PREFIX_TIMEOUT = 2000

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