DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs.

Claude Code v2.1.219

The workshop skill moved from hard-disabled to flag-gated

Not switched on
Useful2 Signal4
Skills Notable

The workshop skill went from permanently off to flag-gated, so remote config could switch it on.

isEnabled now checks tengu_gable_onyx_sluice plus Artifact tool capabilities instead of returning false outright; the gate still falls back to false.

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.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.219: on

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Read once, for one account on one subscription tier, against v2.1.219. It isn't a statement about your account. What a flag value here can and cannot tell you

What

The workshop skill's isEnabled was a function that returned false unconditionally; it is now a composite check, so it can appear for users whose remote config and Artifact tool schema both line up.

Details
  • Gated on the artifacts flag tengu_gable_onyx_sluice, whose fallback is false, so it stays off absent a remote value
  • Additionally requires the Artifact tool schema to expose a capabilities input and a read_page_data action
  • All three conditions must hold before the skill is offered
Evidence

tengu_gable_onyx_sluice

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