What it does

Start is an agent skill from educlopez/ui-craft. Front door. Reads the current project (framework, tokens, brief, spec, harness) and reports what ui-craft can do right now, then routes you to the right next step. Run this first if you're new or unsure where to begin. No code changes. Invoke when the user asks for start on their UI, or mentions 'start' alongside design / UI / frontend work.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design. The repository describes itself as: Design engineering system for AI coding agents — ship UI with craft-level quality. Install as an agent skill. The licence is MIT.

When your agent uses it

  • Asks for start on their UI
  • Mentions start alongside design / UI / frontend work

Example prompts

  • “/start”

Requirements

  • Node.js

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Detect (read-only)
  2. Report the three layers
  3. Recommend ONE next step
  4. Hand off

What it can do on your machine

Read from SKILL.md and the folder at commit ceecc8e. 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

    Shell commands in SKILL.md call:

    • npx

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

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    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

Start loads about 1.5k tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 653 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~87
When it runs · the whole SKILL.md, loaded when a task matches
~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.

description
Front door. Reads the current project (framework, tokens, brief, spec, harness) and reports what ui-craft can do right now, then routes you to the right next step. Run this first if you're new or unsure where to begin. No code changes. Invoke when the user asks for start on their UI, or mentions 'start' alongside design / UI / frontend work.
<!-- HARNESS MIRROR — do not edit here. Canonical source: skills/ or commands/. After editing source, copy into cli/assets/<harness>/ and repo-root harness mirrors. -->

Context: this sub-skill is one lens of the broader ui-craft skill. If the ui-craft skill is also installed, read its SKILL.md first for Discovery + Anti-Slop + Craft Test, then apply the specific lens below.

Orient the user. Load the ui-craft skill, read the current project, and report what ui-craft can do right now for it. This is the front door — most people run it first.

ORCHESTRATE-ONLY RULE

This command detects state and routes. It MUST NOT build, edit, audit, or re-implement any phase logic. It contributes only:

  1. Project detection (read-only).
  2. A "what's available now" map across the three usage layers.
  3. One recommended next step + the command to run for it.

When the user wants to act, hand off to the real command (/brief, /tokens, /sddesign, /craft, /finalize, the review agents, etc.). Do not inline their steps.

Step 1 — Detect (read-only)

Scan the project. Do not write anything. Gather:

SignalHow to detectUsed for
Framework / stylingpackage.json deps, config files, file extensions — Tailwind, CSS Modules, styled-components/Emotion, vanilla CSS, Vue/Svelte/Astro SFCConfirm ui-craft adapts to this stack
Token spineCSS vars (--color-*, --accent-*, --font-*), Tailwind theme.extend, a token fileGate: is /tokens needed?
Brief.ui-craft/brief.md exists?Gate: is /brief needed?
External design contractDESIGN.md or design-tokens.json at repo root (ecosystem convention some teams use)Treat as brief + token input — read it, honor it, don't duplicate it
Spec.ui-craft/spec.md exists? which surfaces?Is there work in flight?
HarnessClaude Code (plugin/skill) vs .codex/.cursor/.gemini/.opencode/.agents mirrorWhich layers are reachable (agents/MCP are Claude Code / MCP-client only)
Existing UIare there components/pages already, or is this greenfield?Build-new vs review/polish framing

Keep detection fast and quiet — a few reads, no deep traversal. Report findings as a short table.

Step 2 — Report the three layers

Print what's available now, mapped to how people actually use ui-craft. Mark each layer ● active / ○ available / – not reachable in this harness.

ui-craft is a design engineering SYSTEM. You're set up for:

● Layer 1 — Just ask
    Describe any UI and the agent designs with taste (anti-slop, system tokens,
    real hierarchy). No command needed. This is the default and the point.

○ Layer 2 — Drive it
    Slash commands for focused passes. Given THIS project:
      <tailored list — see Step 3>

○ Layer 3 — Verify it
    design-reviewer + a11y-auditor agents · ui-craft-mcp gates · UICraftScore · ui-craft-detect CLI.
    <mark – if the harness can't reach agents/MCP, and say so>

Tailor the bullets to the detected state — don't print the generic catalog.

Show full SKILL.md (329 more words)Show less

Step 3 — Recommend ONE next step

Pick the single highest-value next action from detected state. Use this decision order:

  1. No brief, non-trivial project → recommend /brief ("anchor every later decision to your product's principles — 5 min, writes .ui-craft/brief.md").
  2. Brief exists, no token spine → recommend /tokens ("establish the 3-layer token spine so builds match a system, not inline guesses").
  3. Brief + tokens exist, building something net-new → recommend /sddesign <surface> (full pipeline) or /craft <surface> (one-shot) — ask which.
  4. Existing UI to improve → route by intent: review → ui-craft:design-reviewer + ui-craft:a11y-auditor (Claude Code) or /critique + /audit; polish → /polish; simplify → /distill; flat/generic → /bolder; loud/busy → /quieter; dated site to modernize → /redesign.
  5. About to ship / merge → recommend /finalize (10-pass gate) and, for CI, npx ui-craft-detect or the score_ui MCP tool.

Print it as one clear line:

Recommended next: … — <one-sentence why>.

Then offer the full menu only if asked: "Want the full command list, or shall I run that now?"

Step 4 — Hand off

If the user confirms, run the recommended command. Otherwise stop — /start never acts on its own. Its job is done once the user knows where they are and where to go.

Notes

  • Read-only. /start writes nothing and changes no code. The artifacts (brief.md, spec.md, tokens) are written by their own commands.
  • Harness honesty. If the project is in a non-Claude-Code harness (.codex, .cursor, etc.), Layer 3 agents and the MCP server may not be reachable from that agent — say so plainly and point to the CLI (ui-craft-detect) as the portable verify path.
  • Craft-intent routing. Full-surface builds (/craft, /sddesign) declare a Craft Read before code. If the user describes a built UI as "generic", "template-y", or "too safe", route to /bolder; if "too loud" or "too busy", route to /quieter.
  • Don't re-run Discovery. If a brief or spec already exists, don't interrogate the user for preferences — read the artifacts and report.

Next step: Follow the rung this run named. /start is read-only — the value is in doing the one command it picked.
