What it does

UI Design is an agent skill from hashgraph-online/awesome-codex-plugins. Design, build, or improve web and mobile interfaces using real product examples from UIZZE’s 800,000+ web and iOS screens. Use for UI design, UX design, frontend or web design, mobile app UI, responsive layouts, design systems, redesigns, visual polish, interface critique, and requests like “make this UI better.”

Its SKILL.md is about 900 tokens, which your agent loads only when the skill is triggered. The skill folder holds 18 other files, including reference files (for example `MANIFEST.json`, `MODIFICATIONS.md` and `agents/openai.yaml`).

It sits in Frontend & Design, covering UI design, Design systems and UX design. It works with iOS. The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is Apache-2.0.

When your agent uses it

  • Responsive layouts
  • Interface critique
  • Requests like make this UI better

Example prompts

  • “make this UI better.”
  • “/ui-design”

What it can do on your machine

Read from SKILL.md and the folder at commit 78497e5. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

UI Design loads about 904 tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 81 tokens; SKILL.md has 428 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~81
When it runs · the whole SKILL.md, loaded when a task matches
~904
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Uizze UI Design

Work from the product

Read the brief, existing UI, components, tokens, assets, and any PRODUCT.md or DESIGN.md before designing. The user's request and project constraints outrank this skill. Preserve an established visual system for extensions and polish; replace it only for an approved redesign. A new project does not require those files.

Identify the audience, primary task, important states, and intended result. Ask only about missing choices that would materially change the work. A precise request is enough to proceed; do not turn a small fix into a discovery workshop.

Select the workflow

Load the playbook for the requested action, plus the platform and craft guidance needed to execute it:

  • New interface or major redesign: new-work
  • Product or dashboard work: operate
  • Refinement and polish: polish
  • Simplification: distill
  • Explicit audit: audit, read-only unless fixes were requested
  • Native iOS: iOS, alongside the action's playbook
  • Explicit /overdrive, “Uizze Overdrive”, or a request for exceptional interaction work: Overdrive

For implementation, use craft after the direction is settled. Load only relevant files; multiple complementary playbooks are allowed. Overdrive is opt-in, not the default for ordinary UI work. It requires a chosen direction before implementation.

“Use Uizze Overdrive on this screen” works through this router; a native slash command depends on the host. These are self-contained Markdown playbooks, not an installer, background service, or executable engine.

Optional Uizze evidence

Read the reference policy before using find_ui_references or find_ui_materials. Inspect relevant visual evidence when it can inform the layout, state, interaction, or assets. Use the host's available tools, not invented calls or connections. Paid retrieval is optional; missing access does not block local design work.

Distinguish an exact reference, a related example, no match, and a service error. Briefly disclose a limitation that affected the result. Never claim an image was inspected or a state was found without evidence.

Finish

Build the requested scope and exercise its important states. Render and inspect the real result at representative desktop/mobile sizes or native device classes, including the user's reported failing size. Compare it with the chosen direction or supplied reference, not just with the absence of runtime errors.

Fix material problems in a batch, then render and inspect again. Stop once the requested result is verified; do not keep inventing work. If a bounded pass cannot resolve an issue, report it instead of claiming a pass. When rendering is unavailable, distinguish code checks from visual verification.

Keep the handoff concise: what changed, what was actually tested, and any remaining limitation. A skill does not authorize publishing, purchases, new dependencies, account changes, or destructive actions.
