design-ux

design-ux is a skill for Claude Code, Codex from leifericf/agentic-sdk. It costs 12 tokens per session (489 once invoked), scanned A, original, MIT.

A guide for setting user-experience rules and interaction patterns across interfaces such as web, mobile, desktop, terminal, and command line.

In plain words
What is it for?
Use it to define interface surfaces, tone, density, users, accessibility expectations, input methods, and visual references for a product.
Why use it?
It creates shared decisions about how an interface should behave, reducing inconsistent choices across screens and input methods.

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

design-ux 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 5d 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.

What it actually says

design-ux

Establish UX guardrails, visual direction, and interaction patterns across web, mobile, desktop, TUI, and CLI surfaces. Reduce interface entropy with reusable rules. UI only.

Procedure

  1. Read project-meta.md, problem-description.md, product-requirements.md, risk-assumption-review.md, decision-log.md, and open-questions.md. If a prerequisite is missing, return blocked: <which artifact>.
  2. Run the applicability gate. If the project has no user-facing surface (pure library, backend-only service, batch job, data pipeline), do not produce the artifact. Append a decision-log.md row: decision "Skip UX design guide", why "no user-facing surfaces in scope", tradeoff "revisit if a UI is added". Return skipped: no user-facing surface.
  3. Surface and resolve [Blocking] items affecting ux-design-guide.md.
  4. Collect three to five visual references (URLs, screenshots, CLI or TUI tools, or a textual direction). If none, pick a direction: Minimal, Editorial, Playful, Enterprise, Retro, or Luxury.
  5. Clarify, at most three per turn: primary interface surfaces, brand tone, density, target users and context, accessibility expectations, input modalities, offline and latency constraints. Do not assume UI toolkits unless already decided.
  6. Record new decisions in decision-log.md.
  7. Write ~/.agentic-sdk/<project>/artifacts/planning/ux-design-guide.md with: Metadata, Visual References, Design Principles, Interface Surfaces, Accessibility, Typography, Color System, Layout Rules, Components, CLI/TUI Conventions (if applicable), Interaction Patterns, Content Style, UI Definition of Done.

Boundaries

Owns interaction and visual guardrails. design-technical owns system architecture and the stack. Runs only when a user-facing surface exists. Reached by plan-system.

Return

One line: the artifact written (or skipped: no user-facing surface) and a terse status, or blocked: <reason>.

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.
