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.

New workshop-page reminder, still dark

Not switched on
Useful1 Signal4
Artifacts

Claude would be warned not to claim artifact edits on workshop pages, but the flag is off.

A workshop-page instruction is present behind tengu_gable_onyx_sluice, which compiles to false unless a server value enables it.

Feature flag
tengu_gable_onyx_sluice Not enough to say

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

Read once, for one account on one subscription tier, against v2.1.248. It isn't a statement about your account. What a flag value here can and cannot tell you

What

A new check asks whether the page being edited is a "workshop page", and if so adds an instruction telling the model not to claim it edited an artifact when the change actually belongs in that page's workshop file. It sits behind tengu_gable_onyx_sluice, which compiles with a false fallback, so nothing here runs unless a server value turns the flag on.

Details
  • The same flag already guarded an existing workshop edit refusal, so this is a new call site inside a feature that was already dark rather than a new one.
Evidence

changes to this page are made in its workshop file

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