designer

designer is a skill for Claude Code from donald-ada/workinggenius. It costs 69 tokens per session (2,197 once invoked), scanned A, original, MIT.

A design-planning skill for user interfaces that settles the visual direction before implementation and records the chosen style in DESIGN.md.

In plain words
What is it for?
Use it when work includes an interface that people will see. It helps compare an existing style or reference with the desired change, settle the design language, and document it.
Why use it?
It prevents an interface from defaulting to an arbitrary look and makes the visual decisions explicit before developers build the pixels.

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

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 today.

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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Designer

UI built without a style conversation wears the model's default aesthetic — the look it would produce for any product, which means it was chosen for none. That default is momentum, not design. And taste is the fork that belongs most completely to the user's world, yet it's the one the momentum of building never stops to ask about.

The concept: know who is looking and where; name the base and the delta; settle the delta by looking; commit one language as tokens. A design language is a contract between every screen this product will ever have — which is why it is written once, as named values with roles, and not re-decided per screen.

The discipline

  • Audience and context come before taste. Who uses this, on what, for how long, and in what state of mind — a nurse glancing at a phone between patients, an analyst at a desk for eight hours, a buyer deciding in thirty seconds — decides density, type size, motion budget and contrast before anyone has an opinion about colors. Ask it first, in one exchange, because a delta chosen against the wrong audience is a beautiful mistake: the dense dashboard the analyst wanted is unreadable at a glance, and the airy landing page is useless at a desk all day. DESIGN.md records the answer as the first thing a later screen reads.

  • The first question after that is the base — and how much of it survives. An existing surface, a brand guide, a shipped base (13 curated templates live in this skill's bases/ folder — minimal, editorial, neobrutalism, glassmorphism, neumorphism, bento, mono, retro, neon, paper, premium, corporate, claymorphism — vendored MIT from awesome-design-skills, whose full 67-template catalog stays one pull upstream), a famous style, or nothing. Delta zero is adopting: a successful outcome, one exchange, no research. A named delta is a remix: the base survives except where the user has their own understanding. No base is crafting from the problem itself. Cost follows the delta — research only ever covers the part no base answers. A shipped base is a starting token set; its generic rule lists are not this product's rules, and the language is the delta written down.

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.
