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.

Artifacts

An artifact republish switch is exported but nothing in the build reads it.

tengu_cobalt_plinth_thrift is defined and exported with no other occurrence in the bundle.

Feature flag
tengu_cobalt_plinth_thrift 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.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.242: on

Read once, for one account on one subscription tier, against v2.1.242. It isn't a statement about your account. What a flag value here can and cannot tell you

What

A new flag, controlled by tengu_cobalt_plinth_thrift and requiring the value to be exactly true, is defined and exported alongside the other artifact feature checks. The only occurrence of the name in the whole bundle is the export itself, so turning it on server-side today would change nothing.

Details
  • The fallback when the setting is absent is false.
  • The setting name does not exist in v2.1.241.
  • This is a flag plumbed ahead of the code meant to consume it.
Evidence

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