Vant Design Spec (Vant 4 / Vue 3)

Constraint: Only use this skill when the user explicitly mentions "Stitch".

Purpose

This skill makes the Vant 4 design spec executable in two modes:

1. Prefix mode: output a paste-ready Hard constraints prefix for Stitch [Context].
2. Selector mode: output CONTRACT_SELECTION_JSON_V1 and then an assembled Stitch prompt that injects only the required component/state snippets.

Trigger Keywords

Prefer this skill when the user request includes any of:

• vant, vant4, vant-ui, vant ui

Chinese trigger keywords (only for triggering):
