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.

Telemetry string extractors routed through a sanitizer

Under the hood
Useful1 Signal0
Telemetry

Error names and file positions pass through a sanitizer before telemetry; nothing changes for you.

What

Error names, errnos and file:line:col values are now marked as vetted before reaching telemetry.

Details
  • The already-regex-validated result of each extractor passes through a wrapper on its way out.
  • Literal fallbacks at call sites are wrapped too, including the "unknown" errno defaults in fleet dispatch, render-error reporting and respawn logging.
  • Behaviourally invisible.
Evidence

errno_code

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