phoenix-design

phoenix-design is a skill for Claude Code, Codex from All-The-Vibes/ATV-Phoenix. It costs 111 tokens per session (1,368 once invoked), scanned A, original, MIT.

A set of design-engineering guidelines for making software interfaces clear and polished, including deciding when animation helps and reviewing changes before and after. It also calls for checks such as linting, building, and visual or interaction testing where possible.

In plain words
What is it for?
Use it when designing or refining user interfaces, especially their animation, interaction details, visual finish, and regression checks.
Why use it?
It helps prevent decorative motion, overlooked interface details, and visual improvements that accidentally break behavior or the build.

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

phoenix-design 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 1mo 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.

phoenix-design — taste is the differentiator, polished with evidence

Encodes Emil Kowalski's design-engineering philosophy: in a world where everyone's software is good enough, taste is the differentiator, and unseen details compound into interfaces people love without knowing why. Phoenix adds the verify-heal discipline so polish ships without regressing build/lint/behavior.

Core philosophy

  • Taste is trained, not innate. Reverse-engineer great interfaces; understand why they feel right.
  • Unseen details compound. Users rarely notice them consciously — that's the point. The aggregate of invisible correctness is what makes software feel stunning.
  • Beauty is leverage. People pick tools on the whole experience. Good defaults + good motion stand out.

The Animation Decision Framework (answer in order, before writing any animation)

1. Should this animate at all?

Frequency Decision
100+×/day (keyboard shortcuts, command palette) No animation. Ever.
Tens of ×/day (hover, list nav) Remove or drastically reduce
Occasional (modals, drawers, toasts) Standard animation
Rare/first-time (onboarding, celebration) Can add delight

Never animate keyboard-initiated actions — they repeat hundreds of times a day; animation makes them feel slow. (Raycast has no open/close animation. That's optimal for something used constantly.)

2. What is the purpose?

Every animation needs a clear answer to "why does this animate?" Valid: spatial consistency, state indication, explanation, feedback. No purpose → no animation.

3. What curve & properties?

  • Animate specific properties (transform, opacity) — never all (janky, animates the unexpected).
  • ease-out for things entering / responding to user action (instant feedback). ease-in feels sluggish for UI. Custom curves for personality.
  • Nothing appears from nothing: enter with scale(0.95) + opacity, not scale(0).
  • Respond to press: interactive elements get an :active state (transform: scale(0.97)).
  • Scale from origin: popovers/dropdowns scale from their trigger (transform-origin), modals stay centered.
  • Honor prefers-reduced-motion.

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.

phoenix-design is a skill published in the GitHub repository All-The-Vibes/ATV-Phoenix (6 stars, last pushed 6d ago), licensed MIT. It adds 111 tokens to every session and 1,368 once invoked, about $0.0004 per session on Opus 5.5. 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.
