Claude Code v2.1.281 ·

Pending-slot handoff is now keyed

A single-value handoff slot now uses a key, and only a taker with the matching key gets the value

What

Claude Code has a small holder that keeps one pending value until something takes it. A value is now stored under a key, and taking it requires the same key. If the key does not match, the taker gets nothing and the value stays in place.

Why

A value meant for one part of the program can no longer be picked up by another part by mistake.
