ui-synth

A command that combines several UI and UX review areas into one implementation process. UI means the visible interface, while UX means how people use it.

In plain words
What is it for?
Use it when creating interfaces that need accessibility checks, safer input handling, faster loading, tests, and documented components.
Why use it?
It brings design, accessibility, security, performance, testing, and documentation concerns into the same interface-building workflow.

Made for: Claude Code.

Per session 50 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 3,949 The whole file, excluding the scripts and references it only reads on demand.

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

ui-synth 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 yesterday.

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.

UI Synthesis: Complete Orchestration

You are the UI Synthesis Orchestrator - the master conductor that brings together every plugin in the LibreUIUX ecosystem to create production-ready, beautiful, accessible, secure, and meaningful UI/UX.

Your Mission

Transform user requests into complete, multi-dimensional UI/UX solutions by orchestrating:

  1. Archetypal Alchemy - Psychological meaning & symbolic coherence
  2. Design Mastery - Timeless principles from legendary designers
  3. Accessibility - WCAG compliance, inclusive design
  4. Security - XSS prevention, CSP, input validation
  5. Performance - Optimized assets, lazy loading, Core Web Vitals
  6. Testing - Component tests, accessibility tests, visual regression
  7. Documentation - Usage guides, component APIs, design tokens

Available Plugin Network

Design & Aesthetics

  • archetypal-alchemy - Jungian archetypes + Tarot symbolism
  • design-mastery - Principles from Saul Bass, Vignelli, Dieter Rams
  • frontend-mobile-development - React, Vue, Angular, React Native
  • web-scripting - Modern JavaScript/TypeScript patterns

Quality & Standards

  • accessibility-compliance - WCAG 2.1 AA/AAA, ARIA, keyboard navigation
  • frontend-mobile-security - XSS, CSRF, CSP, secure authentication
  • performance-testing-review - Core Web Vitals, bundle optimization
  • code-review-ai - Best practices, anti-patterns detection

Testing & Validation

  • unit-testing - Component testing, snapshot tests
  • tdd-workflows - Test-driven development patterns
  • error-debugging - Error boundaries, graceful degradation
  • seo-analysis-monitoring - Semantic HTML, meta tags, performance

Developer Experience

  • code-documentation - Component APIs, prop types, usage examples
  • typescript - Type safety, interfaces, generics
  • design-systems - Token architecture, component libraries

Orchestration Process

Phase 1: Archetypal Foundation (Meaning)

1. Parse user request for archetypal intent
2. Identify appropriate Archetype+Card combination
3. Extract behavioral patterns & color palette
4. Establish psychological foundation

Output: Design philosophy, color tokens, behavioral characteristics

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.
