ui-craft

ui-craft is a skill for Claude Code, Codex from MemTensor/memmy-agent. It costs 86 tokens per session (2,203 once invoked), scanned A, original, MIT.

A workflow for designing and checking browser-based interfaces such as websites, dashboards, and forms. It covers the page layout, visual style, interaction states, responsive behaviour, and accessibility.

In plain words
What is it for?
Use it to build or redesign HTML, CSS, JavaScript, React, Vue, or Svelte interfaces and inspect how they look and behave in a browser.
Why use it?
It makes the interface reflect its users and main task instead of treating the page as code alone. It also checks less obvious states such as loading, errors, empty results, disabled controls, and different screen sizes.

About the project

Memmy is a local memory hub that gives multiple AI agents one shared, persistent context about their user. It helps people continue work across agents such as Claude Code, Codex, OpenClaw, and Hermes Agent. The catalogue entries are skills for using Memmy with supported agents.

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-craft 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.

UI Craft

Create an intentional interface, not merely valid frontend code. Make the page fit its product, help the user act, and hold up under real browser inspection.

Establish the design brief

Before editing, identify:

  • the user and the situation in which they reach this interface;
  • the primary job, decision, or action the interface must support;
  • the information that must be noticed first, second, and later;
  • the dominant behavior: scan, operate, enter, compare, learn, or explore;
  • the important default, loading, empty, error, success, disabled, and permission states;
  • the target viewports, input methods, accessibility needs, and engineering constraints.

Ask a small number of focused questions only when a missing answer would materially change the result. Otherwise proceed with conservative assumptions and preserve the user's scope.

Read the existing visual language

Inspect the rendered page and the source that actually defines it. Read relevant:

  • routes and page composition;
  • layout shells and navigation;
  • theme, token, and global style files;
  • nearby components and their variants;
  • typography, icons, imagery, and other assets;
  • copy conventions and product terminology;
  • responsive rules and existing breakpoints.

Treat the repository as the source of truth. Reuse its components and tokens before adding new ones. Do not introduce a parallel palette, spacing scale, radius family, shadow language, or component pattern for one screen.

Preserve the established product language unless the request explicitly calls for a redesign. If the current interface is inconsistent, improve the requested surface without casually rewriting unrelated global styles.

Choose the composition before decoration

Let the dominant user behavior determine the page structure:

  • For scanning or monitoring, favor density, stable alignment, glanceable status, and clear exceptions.
  • For operating or managing, favor selection state, nearby actions, feedback, and efficient repeated work.
  • For entering or configuring, favor grouping, progressive disclosure, validation, and a clear completion path.
  • For comparing, align equivalent information and make differences easy to inspect.
  • For learning or deciding, build a paced narrative with one clear idea or action at a time.
  • For exploring, make search, filters, results, preview, and wayfinding the primary composition.

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.
