A rewritten HTML-first workshop skill sits behind gate tengu_gable_onyx_sluice plus Artifact tool capabilities, all off here.
The bundled workshop skill text was rewritten around two authoring lanes, with HTML promoted over markdown, though the skill is not offered on this build.
- v2.1.218 said flatly that the workshop document is markdown and stays markdown for its whole life.
- A new "Choosing the lane" section tells the model to copy a template to a path ending in
.workshop.html, fill it, and publish that file. - The markdown
.workshop.mdlane becomes secondary, reserved for when the user asks for markdown or the document will be dominated by quoted external content. - Publishing runs a structural verifier on the final payload of every publish and refuses out-of-contract pages: fixed scripts, no inline
on*handlers, no iframes/forms/base/link, escaped quoted content, island and markup agreement. - Registration uses
isEnabledbacked by gatetengu_gable_onyx_sluicewith in-source fallback false, so absent a remote value the skill is not offered; it additionally needs the Artifact tool'scapabilitiesand theread_page_dataaction.
Default to the TEMPLATE-HTML lane
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
