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.

Error Handling

Tokens and passwords caught in error text are now redacted before you or your logs see them.

What

Short error and detail summaries are run through a redactor before display, so tokens pasted into error strings do not leak into output or logs.

Details
  • Rewrites bearer and basic values, and token/key/secret/password/authorization/credential assignments of 8 or more characters, to "[redacted]".
  • Runs after a byte-safe truncation of the summary.
  • Unconditional; no gate.
Evidence

/\b(bearer|basic)[\s:=\uFF1A\uFF1D]+([A-Za-z0-9._~+/=%-]{8,})/gi

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