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.

Claude Code v2.1.251

Workflow scripts outside readable paths are now denied

You'll notice
Useful3 Signal2
Workflows

A workflow whose script sits outside your readable paths is now denied outright.

What

If a workflow's script file sits outside the set of paths the session is allowed to read, the tool now denies the call outright instead of quietly carrying on.

Details
  • The denial happens in the workflow tool's permission check, so it is reported as a permission failure rather than a missing file.
Evidence

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