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.

Pasted image IDs come from a counter

Under the hood
Useful2 Signal1
Input

Pasted image numbering comes from a counter instead of rescanning your whole conversation.

What

The code that worked out the next pasted-image ID by scanning every user message for the highest one is gone; the UI is handed the last issued ID directly, so IDs no longer depend on re-reading conversation history.

Evidence

lastMintedPasteId

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