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.
Tagged-input attributions now serialize from and from-name attributes (with quote-stripping on the display name) into the system-reminder block, so multi-user sessions can show who supplied each piece of context.
Evidence
Attribution serialization (search for "from-name=\"").
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
