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.

Transcript reads refuse anything that is not a regular file

Resuming can no longer hang on a transcript path that is a directory or pipe.

What

Before reading the start and end of a transcript file, Claude Code now checks that the path is a regular file and returns empty content otherwise. This closes a case where a resume candidate that was a directory, device or named pipe could hang or return garbage.

Details
  • The check runs on both the path and the opened handle, and only on read-only opens.
  • Resolving resume paths now goes through a shared helper that falls back to the original path when the real path cannot be determined.
Evidence

{ head: "", tail: "" }

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