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 v2.1.227

Blocked hosts in the sandbox can now explain why

You'll notice
Useful3 Signal2
Sandbox

Sandbox-blocked hosts can now tell you the specific reason they were denied.

What

The generated sandbox network policy now includes a per-domain reason for each blocked host. The enforcement side already looked for these and fell back to a generic message, so blocked requests can now say something more specific than "host is on the deny list".

Evidence

host is on the deny list

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