Source Intelligence

DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.239

Commands that produce too much output now say so

You'll notice
Useful3 Signal1
Bash Tool

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.
