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.

Fast-path eligibility now records why it declined

Under the hood
Useful2 Signal2
Diagnostics

The fast-path check now records why it declined; the decisions are unchanged.

What

The check that decides whether a request can use the fast gateway path now returns a reason along with its yes/no answer, so refusals can be reported in diagnostics. The answers themselves are unchanged.

Details
  • Reasons: unpinned_gateway, third_party_provider, custom_base_url, sandboxed_entrypoint, unsupported_subscription, no_auth.
Evidence

sandboxed_entrypoint

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