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 v2.1.242

Crash reports hold back messages from errors thrown outside Claude Code

You'll notice
Useful3 Signal2
Telemetry

Crash reports replace messages from errors thrown entirely outside Claude Code, so your data stays out.

What

When every frame of a crash comes from somewhere other than Claude Code's own code (native frames, dependencies, Node or Bun internals) and the error carries no code, the message is replaced with a fixed phrase naming the kind of error, so text that might contain your data is not sent.

Details
  • Applies always in the error report builder; stack frames, the fingerprint and the tags block (platform, OS release, entry point, model, session kind, renderer mode) are unchanged.
Evidence

thrown outside the Claude Code bundle

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