What
When Claude Code checks output against a JSON schema (a description of the shape the output must have), it now does so through a shared helper. That helper sets a precision of six decimal places for the multipleOf rule, which requires a number to be a multiple of a given value. Other checks behave as before.
Why
Output using multipleOf with decimal numbers may now pass or fail slightly differently than before.
