What
When Claude uses a tool, it sends instructions to it called tool input, and that input arrives in pieces. Claude Code has a step that repairs input that came through garbled.
Repair now skips input that is already valid. Before, it always ran.
A new check looks for escaped characters, written as \u followed by four characters, in certain tool input.
Why
This affects how Claude Code handles tool input that arrives mangled, and leaves input that is already fine as it is.
