What probably matters to youSection of the release
A plan-mode prototype-artifact offer prompt exists but its guard is hardcoded to false.
What
Plan mode can offer to build a prototype artifact before the plan is executed, but the section is never appended in this build.
Details
the plan-mode system reminder gains a prototypeOffer: !0 field and a "## Prototype Artifact Option" prompt section
the section tells Claude that if the user accepts, the prototype is built after plan mode ends, plan mode stays read-only except for the plan file, the plan file should name the prototype-first approach, and the prototype skill is invoked once plan mode has ended
the reminder emits a plan_prototype_offer marker alongside the existing plan_workshop_offer
guarded by isPlanPrototypeOfferEnabled, which is Lgo() && !B5(); Lgo returns !1, so the guard is constant false
Evidence
## Prototype Artifact Option
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
