What

Claude Code records usage data each time its Bash tool (the tool Claude uses to run terminal commands) finishes or fails a command. Those two records, tengu_bash_tool_command_executed and tengu_bash_tool_command_failed, no longer include the builtin_capture field. Separately, the Bash tool's check on file history now receives extra information about the current session.

Why

This only changes what is recorded about commands; running commands works the same way.
