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.

Expired pastes are dropped from the prompt with an explanation

You'll notice
Useful3 Signal1
Input

Expired pastes are dropped from your prompt with a notice instead of sending a placeholder.

What

If a pasted block is no longer available when you submit, it is now removed from the prompt and you get a notice saying so, instead of a literal placeholder being sent to the model.

Details
  • The old placeholder text "[Pasted text #N — content no longer available]" has been removed.
  • Pastes flagged as unavailable are excised from both the shortened and fully expanded prompt.
  • The notice is built from "is no longer available and was removed from the prompt", with a plural form "are no longer available and were removed from the prompt", and labels the item either "Pasted text" or "Truncated text".
Evidence

is no longer available and was removed from the prompt

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