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.

Safety-refusal messages rewritten

You'll notice
Useful2 Signal0
Elsewhere

Refusal messages are shorter, tell you to start a new session, and link somewhere to learn more.

What

The generic Usage Policy refusal now says the model can't help and tells you to start a new session to continue, instead of the older longer text. A learn-more/feedback line is appended, and it differs depending on whether you are running through the SDK or interactively.

Details
  • the generic refusal names the model and directs you to start a new session
  • the cyber-topic variant is reworded around "safeguards flagged this message"
  • applies to everyone, no gate
Evidence

can't help with this. Start a new session to continue.

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