Claude Code v2.1.239 ·

Commands that produce too much output now say so

A command that floods its output is now reported as truncated instead of looking like a crash.

What

When a spawned command exceeds the output buffer limit, the helper that runs it now returns an explicit overflow marker alongside the exit code instead of a generic failure, so the code that called it can tell truncated output apart from a crashed command.

Evidence

execFileNoThrow maxBuffer exceeded

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
