grok-designer is a skill for Claude Code from skillmds/skillmd. It costs 180 tokens per session (5,756 once invoked), scanned A, original, MIT.

A guide that requires Grok 4.5, an external AI model, to advise on visual and user-experience design decisions.

In plain words

Why use it?
It provides a separate review of interface quality, user flows, layout, colour, typography, and interaction choices.

Skill for Claude Code

Written for Claude Code: shipped in a Claude Code plugin.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is -f ./src/styles/tokens.css \.

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

grok-designer 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 4d 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.

Grok Designer — UI, UX, and Visual Design Advisor

Use Grok 4.5 as an external advisor for visual design, UI finish, UX task flow, interaction friction, art direction, and lightweight design artifacts.

Critical rules

  • ONLY interact with Grok through the global grok-designer CLI. Do not call the API or provider-specific scripts directly.
  • When this skill is used, call grok-designer before giving UI advice, UX advice, design imagery, art direction, critique, visual advice, HTML, or SVG output. Do not write those deliverables from the agent's own judgment.
  • Call grok-designer directly in the normal path. If the command is missing, install it silently with the bundled scripts/install_cli script, then retry.
  • For visual/UI review of existing files, use grok-designer ui.
  • For UX, task-model, component-choice, interaction-flow, friction, or state-behavior review, use grok-designer ux.
  • For requests that need both UI and UX review, run ui and ux independently. You may use the CLI's comma-separated form, such as grok-designer ui,ux ..., or run separate commands in parallel.
  • For broad art direction, use grok-designer direction. It may include files as background context.
  • For design imagery markdown, use grok-designer direction and read the generated markdown before responding.
  • For new standalone HTML/SVG design drafts, use grok-designer html or grok-designer svg.
  • For a single handwritten SVG brand wordmark, lettering mark, signature mark, or logo-like text asset, use grok-designer svg.
  • For a comparison sheet with multiple wordmark candidates, use grok-designer html.
  • If the user provides screenshots, mockups, moodboards, or visual references, include relevant images with -i / --image when they help Grok judge visual style, layout, hierarchy, mood, fidelity, interaction sequence, or state transitions.
  • Grok is stateless. It does not know the current project, prior conversation, screenshots, local files, design rules, or previous Grok outputs unless they are included in the current command.
  • Do not ask Grok to review code quality, technical debt, CSS lint, engineering consistency, performance, or architecture unless the user explicitly asks. Keep Grok focused on what users can perceive and operate.
  • Do not ask Grok to output code patches or diffs for existing files. Use its design advice, then make the actual edits yourself.
  • After Grok returns UI advice, UX advice, design imagery markdown, visual direction, or an HTML mockup, show the output or a concise summary to the user and wait for confirmation before implementing it in project code, unless the user explicitly asked to implement immediately.
  • Because UX changes often affect state logic, routing, form behavior, data loading, or validation, present a summary of structural/logic changes and wait for confirmation before refactoring component logic unless the user explicitly asked to implement immediately.
  • After html or svg returns, do not start an extra AI review, visual critique, browser screenshot check, grep/tail completeness check, or refinement loop unless the user explicitly asked for checking or iteration. The CLI performs structural integrity checks before writing generated HTML/SVG. Read enough to know what Grok returned, then present it to the user.
  • For ordinary HTML, SVG, or icon requests, run the script ONCE per task. Read the output file and proceed.
  • Pass the user's stated requirements and concrete project context. Do not add the agent's own style labels, layout choices, color choices, metaphor choices, interaction concepts, or evaluation criteria unless the user explicitly said them.
  • Do not pre-design for Grok. For creative generation, state the user goal, source material, output format, and hard constraints only. Do not name visual directions, metaphors, layouts, palettes, typography, materials, animations, or interaction models unless the user explicitly provided them.
  • For multiple alternatives, ask Grok for independent, clearly different options. Do not assign the options names like "dashboard direction", "editorial direction", or "radar direction" unless the user gave those directions.
  • The CLI manages its own configuration and authorization. Do not pre-check authorization. If a call fails with error=not_authorized, report that Grok Designer is not authorized.

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.
