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.
Redirects into refused hosts fail without retrying
Under the hood
Useful1Signal1
Internals
In the test network guard, a redirect to a blocked host fails immediately instead of retrying.
What's wrong with this entry?
Anonymous. No account, no email.
What
In the test-only network guard, a response that was redirected to a disallowed final URL now raises an egress error, and the retry logic treats that error as permanent so it is not attempted again.
Details
The error carries the code TestEgressBlocked.
Inert outside the test harness.
Evidence
TestEgressBlocked
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
