What

The usage data Claude Code sends when it runs a shell command through its Bash tool (the tool that runs terminal commands) now includes a builtin_capture field. The data sent when a Bash command fails gains the same field.

Why

The field suggests Claude Code is measuring a built-in way of capturing a shell command's output.
