Source Intelligence

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.

WebFetch validates redirect targets before showing them

You'll notice
Useful2 Signal1
WebFetch

Redirected fetches now tell you the page moved and was not fetched for you automatically.

What

When a fetch redirects, WebFetch now parses and checks the destination before relaying it, and says the page was at a location that was not fetched automatically rather than that it redirects to a different host.

Details
  • Non-http(s) destinations are withheld entirely.
  • Over-long URLs are truncated with a note; hostnames longer than a valid DNS name are flagged as unfetchable.
  • Only a clean, complete destination gets the follow-up instruction to call WebFetch again with those parameters.
Evidence

REDIRECT DETECTED: The URL redirects to a location that was not fetched automatically.

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