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.

IPC diagnostics redact tokens and long hex strings

Under the hood
Useful2 Signal2
Internals

Local messaging logs now hide tokens and long hex strings instead of printing them.

What

Log output from the local messaging transport now replaces runs of 32 or more hex characters with a <hex:...> placeholder, and refuses to print any fragment whose text matches /token/i, substituting a withheld marker instead. Applied to peer addresses and error fragments.

Evidence

(redacted: fragment may carry an auth token)

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