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.

An artifact plan template and a stricter HTML sanitizer

Not switched on
Useful2 Signal4
Artifacts

A template for rendering plans as artifact pages ships with a stricter sanitizer.

The plan artifact template is bundled with no visible render site.

What

A new embedded HTML template for rendering plans as artifacts ships alongside the existing workshop templates, with a hardened sanitizer. Nothing in this build shows where the plan template gets rendered, so it may not be reachable yet.

Details
  • The sanitizer strips iframe, embed, object, base, form, link, noscript, frameset, frame, plaintext and the SVG animation elements.
  • Collected results use a list type that stops accepting entries past a cap and records an overflow marker instead of growing without bound.
Evidence

templates/artifact-plan.html

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