Shadcn Component Authoring Skill

Goal

Define a repo-owned skill for building new shadcn-style components in Plate: preserve shadcn open code, extract only the right package seams, and encode the real local patterns instead of generic UI advice.

Scope

• audit current registry UI/components and package seams
• design the new skill in the repo’s source-of-truth format
• add any rule/reference files the skill needs
• sync generated skill output

Non-Goals

• fixing every over-extracted component now
• broad component refactors outside what is needed to define the skill
• updating external plugin skills in place

Current Findings

• repo-owned skill source of truth is .agents/rules/*.mdc; never edit generated SKILL.md directly
• .agents/skills/shadcn/ already contains the local synced copy of the plugin shadcn skill plus its bundled rule/reference files
• the new skill should match that writing style but encode Plate-specific component and extraction rules

Working Plan

• audit existing registry UI/component patterns and seams
• define the skill structure and supporting reference files
• write the source-of-truth rule file
• add bundled references/rules/assets if needed
• run bun install to sync generated skill output
• run targeted verification on the new skill artifacts
