A design-analysis skill that turns screenshots or mockups into a practical guide for building the same interface. It records layout, fonts, colors, spacing, component states, and responsive behavior using the image and the code repository.

Use it to document a design system, plan reusable interface components, identify needed assets, and compare the design with an existing project's styles.

It removes the guesswork involved in copying a design from an image and helps separate what is visible from what must be inferred.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00026	$0.00460
Opus 5	$0.00013	$0.00230
Sonnet 5	$0.00005	$0.00092
Haiku 4.5	$0.00003	$0.00046

Security

Grade A, and why

ui-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 11d 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

Rylai Codex-Hermes-Claude Edition | Original portable workflow by Rylai

Runtime Compatibility

Codex: install under ~/.agents/skills/ui-designer.
Hermes: install under ~/.hermes/skills/ui-designer or expose the bundle through skills.external_dirs.
Claude Code: install under ~/.claude/skills/ui-designer or <project>/.claude/skills/ui-designer.
Claude.ai and Cowork: upload and enable the matching per-skill ZIP.
Resolve bundled files relative to this skill directory; do not depend on paths from another machine.
Check tools, packages, credentials, network access, and runtime capabilities before execution.

Portable UI Designer

Extract an implementation-ready design system from supplied screenshots or mockups.

Workflow

Inspect the original image at sufficient resolution.
Identify layout grid, spacing rhythm, typography, color roles, radii, borders, shadows, icon style, and component states.
Separate observed properties from inferred behavior.
Compare the extracted system with the target repository's existing framework and design tokens.
Produce a concise implementation specification covering components, responsive behavior, assets, and interaction states.
Implement only when requested, then verify the result against the reference at desktop and mobile sizes.

Bundled Templates

assets/design-system.md: evidence-based visual-system extraction.
assets/app-overview-generator.md: concise product and workflow brief.
assets/vibe-design-template.md: implementation handoff prompt.

Boundaries

Do not invent hidden screens, states, fonts, or assets without labeling them as assumptions.
Prefer the repository's installed component and icon libraries.
Keep text and controls within stable responsive bounds.

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
