What

The telemetry events fired when a bash command succeeds (tengu_bash_tool_command_executed) or fails (tengu_bash_tool_command_failed) now include a much richer breakdown of the parsed command, on top of the existing command_type field:

  • the command's class and its first argument (argv0)
  • the last command's argv0 in a chain
  • whether it used pipes, redirects, chains, subshells, or heredocs
  • a count of simple commands within it
Why

This gives more detailed visibility into the structure of bash commands being run, which can help with understanding usage patterns and diagnosing issues, though the underlying tengu_bash_tool_command_executed and tengu_bash_tool_command_failed gates have no recorded reading yet.
