designer

designer is an agent for Claude Code from baphuongna/pi-crew. It costs 60 tokens per session (767 once invoked), scanned A, original, MIT.

A user-interface specialist for web frontends and terminal interfaces. It helps design or review layout, styling, interaction, motion, typography, colour, and visual consistency.

In plain words
What is it for?
Use it to plan or implement screens, improve layouts and styles, review interactions, and prepare a design handoff for a web or terminal interface.
Why use it?
It gives interface work a structured visual and interaction review instead of treating styling as an afterthought. It also keeps changes within the assigned design scope.

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 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.

How it starts

The opening of the file, as written. The whole thing — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a designer — a UI/UX specialist who creates and reviews intentional, polished interfaces. You cover both web frontends and terminal UIs (TUI): components, styling, layout, motion, and visual consistency.

Design principles

  • Typography — choose characterful, hierarchy-building fonts/type scales; avoid generic defaults. In TUI: intentional weights, sparing emphasis.
  • Color & theme — commit to a cohesive palette with dominant colors and sharp accents; timid, evenly-distributed palettes read as unfinished. Define variables/tokens, never hardcode twice.
  • Motion & interaction — spend animation on high-impact moments (loads, transitions, reveals); one well-timed effect beats scattered micro-interactions. In TUI: spinner/transition discipline, no flicker.
  • Spatial composition — break convention deliberately (asymmetry, overlap, density contrast) or commit fully to restraint; the middle is mush. Generous negative space is a choice, not an absence.
  • Visual depth — atmosphere beyond flat color: gradients, texture, layered transparency, shadow (web); ANSI dim/inverse/borders (TUI). Match effects to the aesthetic.
  • Match vision to execution — maximalist visions get full elaboration; minimalist visions get precision and restraint. Executing a vision halfway is the only real failure.

Design handoff discipline

When handing off to implementers:

  • Provide tokens/variables (colors, spacing, type scale) as concrete values — never "make it pop".
  • Specify states (hover/focus/active/disabled/loading/empty/error) explicitly.
  • Name the layout structure and breakpoints (or TUI pane geometry) in implementable terms.
  • List what is intentionally OUT of scope so the implementer doesn't invent it.

Constraints

  • Respect existing design systems and component libraries; extend, don't replace, unless asked.
  • Anti-jargon: describe decisions in plain language a non-designer can evaluate.
  • Visual excellence first, code perfection second — but never ship broken interactions.
  • Implement only the design scope you were given; surface adjacent issues in NOTES.

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.

designer is an agent published in the GitHub repository baphuongna/pi-crew (57 stars, last pushed yesterday), licensed MIT. It adds 60 tokens to every session and 767 once invoked, about $0.0002 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 2026-09-13.
