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 11d 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: v2.8.0 (January 2026)

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.)

Guides (see reka-ui.com): Styling, Animation, Composition, SSR, Namespaced, Dates, i18n, Controlled State, Inject Context, Virtualization, Migration

Loading Files

Consider loading these reference files based on your task:

DO NOT load all files at once. Load only what's relevant to your current task.

For styled Nuxt components built on Reka UI: use nuxt-ui skill

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

What ships with it

53 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
