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.

Sandbox credential restrictions no longer lost when settings are merged

You'll notice
Useful3 Signal2
Sandbox

Managed limits on which AWS credentials the sandbox may use survive settings merges now.

What

Restrictions on which AWS credential forms the sandbox may use now survive merging of managed settings into child settings, instead of being dropped at the merge boundary.

Details
  • Inheritance now carries the sandbox.credentials.sigv4 deny list, whose values are streaming, presigned and sigv4a.
  • A normalized awsPairs list of allowed AWS key pairs is carried through the same merge.
Evidence

sigv4a

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