creo-ux-internal

creo-ux-internal is a skill for Claude Code from oyusypenko/creo. It costs 69 tokens per session (1,205 once invoked), scanned A, original, MIT.

A user-experience reviewer for analyzing an application's own screens and user flows. It combines screenshots, code reading, and live browser testing to examine how people complete tasks.

In plain words
What is it for?
Use it to review a specific flow or the whole application, map user journeys, identify pain points, and propose concrete interface simplifications.
Why use it?
It helps reveal confusing steps, usability problems, and violations of common interface guidelines. It also organizes findings around user goals and established usability principles.

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

creo-ux-internal 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.

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.

Internal UX Analysis

Analyze your own application by combining existing screenshots, code reading, and live UI testing. Documents findings using JTBD framework, Nielsen's heuristics, and journey maps, then proposes concrete simplifications.

Core Instructions

Configuration

  1. Check for project-specific config at .claude/project-config.md
  2. Read dev_server_url (default: http://localhost:3000), screenshots_path, reports_path c3. Load project extension if it exists at .claude/skills/creo-ux-internal/creo-ux-internal-{project_id}.md. This file contains project-specific user flows, JTBD, domain terminology, and feature mapping. {project_id} comes from project-config.md. Always load it before doing work.
  3. If no config exists, use defaults or ask user

Phase 0: Screenshot Analysis (Do First)

Check for existing screenshots in screenshots/ or .claude/screenshots/.

  1. Read all screenshots using the Read tool (multimodal)
  2. Create initial observations table: Screenshot, First Impression, Obvious Issues, Questions
  3. Identify patterns across screens (consistency issues, repeated problems)
  4. Note specific elements that need live testing verification
  5. Document hypotheses to verify in Phase 2

What to look for in screenshots:

  • Visual hierarchy: Is the most important info prominent?
  • Information density: Too much or too little on screen?
  • Button placement: Are CTAs obvious and accessible?
  • Form design: Are fields grouped logically?
  • Navigation clarity: Can user understand where they are?
  • Error states, empty states, loading states
  • Mobile readiness

Phase 1: Code Analysis

Read project overview and architecture rules first. Then analyze:

  • Data models and relationships
  • State management patterns
  • API endpoints and data flow
  • Decision points and branches

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.
