coach: Skill for Gemini CLI

.gemini/skills/reka-ui/SKILL.md

reka-ui is a skill for Gemini CLI from watt-mind/coach. It costs 47 tokens per session (1,165 once invoked), scanned A, original, Apache-2.0.

A guide for Reka UI, a collection of unstyled Vue components designed to provide accessible behavior such as dialogs, menus, forms, and popovers. It explains how to control their state, compose them, virtualize large lists, and add styles.

In plain words
What is it for?
Use it when building headless Vue components, where behavior and accessibility come ready but the visual design is supplied separately. It also applies to projects using Nuxt UI or shadcn-vue built on Reka UI.
Why use it?
It helps developers build accessible interface components without having to implement keyboard behavior and related interaction patterns from scratch.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

reka-ui scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/generate-components.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Reka UI

Unstyled, accessible Vue 3 component primitives. WAI-ARIA compliant. Previously Radix Vue.

Current version: v2.7.0 (December 2025)

When to Use

  • Building headless/unstyled components from scratch
  • Need WAI-ARIA compliant components
  • Using Nuxt UI, shadcn-vue, or other Reka-based libraries
  • Implementing accessible forms, dialogs, menus, popovers

For Vue patterns: use vue skill

Available Guidance

File Topics
references/components.md Component index by category (Form, Date, Overlay, Menu, Data, etc.)
components/*.md Per-component details (dialog.md, select.md, etc.)

New guides (see reka-ui.com): Controlled State, Inject Context, Virtualization, Migration

Usage Pattern

Load based on context:

Key Concepts

Concept Description
asChild Render as child element instead of wrapper, merging props/behavior
Controlled/Uncontrolled Use v-model for controlled, default* props for uncontrolled
Parts Components split into Root, Trigger, Content, Portal, etc.
forceMount Keep element in DOM for animation libraries
Virtualization Optimize large lists (Combobox, Listbox, Tree) with virtual scrolling
Context Injection Access component context from child components

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
