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.

Directory and working-directory control errors are redacted in some sessions

Under the hood
Useful2 Signal3
Remote Control

Some sessions now get generic errors for add-directory and set-cwd instead of local paths.

What

Failures from the add_directory and set_cwd control requests now pass through a wrapper that substitutes a generic message when a session-level condition holds, so clients see less about local paths and error causes. A set_cwd rejection can be replaced wholesale, and a successful staged add_directory can return an empty payload rather than the staged path.

Details
  • Both paths also gained a stage-logging call on failure.
  • The condition that triggers redaction is a predicate on the session; which sessions satisfy it is not decided at this call site.
Evidence

set_cwd: request rejected

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