Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00058 | $0.00524 |
| Opus 5 | $0.00029 | $0.00262 |
| Sonnet 5 | $0.00012 | $0.00105 |
| Haiku 4.5 | $0.00006 | $0.00052 |
Grade A, and why
cuelabs-design-standard 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CueLABS Design Standard
Maintain design artifacts as implementation contracts. Preserve each product's visual identity while keeping shared foundations, naming, accessibility, and QA methods consistent.
Read the relevant references
- Read references/figma-and-design.md for design documentation, variables, components, states, prototype wiring, content integrity, and Figma-specific constraints.
- Read references/qa-loop.md when planning or closing design and implementation audit/fix/re-verify rounds.
Workflow
- Inspect product decisions, design documentation, current code, and the actual design file before changing either side.
- Determine whether the task affects foundations, components, screens, content, flows, accessibility, motion, or parity.
- Keep product tokens in true light/dark modes and pair accent fills with explicit on-accent text tokens.
- Build screens from live component instances and include required default, empty, loading, error, and destructive states where the product contract calls for them.
- Keep implementation notes in component descriptions or documentation, not visible product canvases.
- Wire and verify named prototype flows. Prove core-flow reachability and eliminate unintended dead ends.
- Run independent completeness, content, accessibility, and polish passes. Record findings with stable node or file identifiers and severity.
- Verify each fix against the artifact and update the implementation contract when a design decision changes.
Guardrails
- Do not fabricate customer claims, usage numbers, pricing, research results, or third-party endorsements.
- Do not ship a screen that lacks its required states.
- Do not represent dark mode as component variants when token modes are the governing mechanism.
- Do not treat screenshots as a substitute for inspectable tokens and components.
- Do not mark a QA finding resolved based only on the builder's statement.
- Do not force a shared visual style where the standard requires only shared structure or behavior.
What ships with it
3 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.
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.

cuelabs-design-standard is a skill published in the GitHub repository cuesoftinc/oss-engineering-standards (2 stars, last pushed 1mo ago), licensed MIT. It adds 58 tokens to every session and 524 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
design-taste-frontend
Anti-slop frontend skill for landing pages, portfolios, and redesigns. The agent reads the brief, infers the right design direction, and ships interfaces that do not look templated. Real design systems when applicable, audit-first on redesigns, strict pre-flight check.
image-to-code
Elite website image-to-code skill for Codex. For visually important web tasks, it must first generate the design image(s) itself, deeply analyze them, then implement the website to match them as closely as possible. In Codex, it must prefer large, readable, section-specific images instead of tiny compressed boards…
design-taste-frontend-v1
The original v1 taste-skill, preserved for projects depending on its exact behavior. The current default is design-taste-frontend (v2 experimental), which is a substantial rewrite. Use this v1 install name only if you need exact backward compatibility.
redesign-existing-projects
Upgrades existing websites and apps to premium quality. Audits current design, identifies generic AI patterns, and applies high-end design standards without breaking functionality. Works with any CSS framework or vanilla CSS.
high-end-visual-design
Teaches the AI to design like a high-end agency. Defines the exact fonts, spacing, shadows, card structures, and animations that make a website feel expensive. Blocks all the common defaults that make AI designs look cheap or generic.
industrial-brutalist-ui
Raw mechanical interfaces fusing Swiss typographic print with military terminal aesthetics. Rigid grids, extreme type scale contrast, utilitarian color, analog degradation effects. For data-heavy dashboards, portfolios, or editorial sites that need to feel like declassified blueprints.
