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.

SDK subprocess errors carry an error class and sanitized message

Under the hood
Useful2 Signal0
SDK

SDK subprocess failures are now grouped by cause with paths and stderr scrubbed from reports.

What

Errors from the SDK's subprocess transport are wrapped with a redacted telemetryMessage and an errorClass so failures can be grouped.

Details
  • classes include spawn_failed, process_exited_nonzero, process_killed_by_signal, executable_not_found and control_request_failed
  • covers spawn failures, non-zero exits, signal kills, aborts, control-request failures and error results
  • stderr tails and filesystem paths are redacted before being attached
Evidence

process_killed_by_signal

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