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.
The check for script-only artifact HTML now parses markup properly instead of string-matching.
What's wrong with this entry?
Anonymous. No account, no email.
What
The check for whether a piece of artifact HTML is nothing but <script> blocks now parses attributes and quoting properly instead of searching for a literal closing tag, and refuses input that mixes comments with script tags.
Details
The media-type parser was switched to the same dedicated whitespace trimmer.
Evidence
<script>
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
