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.

User messages can be marked ephemeral

Under the hood

Elsewhere

What

Details
  • Accepted by the user-message constructor and carried on queued and persisted messages.
Evidence

ephemeral: r,

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