platform: Skill for Claude Code

.agents/skills/design-taste-frontend/SKILL.md

design-taste-frontend is a skill for Claude Code, Codex from tutur3u/platform. It costs 19 tokens per session (333 once invoked), scanned A, a copy of design-taste-frontend-v1, Apache-2.0.

A set of instructions for designing and building web interfaces with deliberate visual style and structured frontend code. It sets default preferences for visual variation, animation, and screen density.

In plain words
What is it for?
Creating React or similar frontend interfaces, choosing layout and motion styles, organizing components, and verifying dependencies before adding libraries.
Why use it?
It gives an AI coding agent consistent design constraints and requires it to check whether third-party libraries are already installed before using them. This helps avoid unexplained dependencies and generic-looking interfaces.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is tutur3u/platform's own configuration. It tells Claude Code and Codex how to work on platform itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything platform configures →

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

design-taste-frontend 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 4d 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

Expressive Frontend Design

Start from the product's audience, primary task, existing visual system, and the requested degree of change. Choose density, composition, and motion to serve that context. A routine component fix does not call for a new design system.

  • Establish clear hierarchy with type, spacing, and grouping. Use cards where they communicate a unit of content or action; use open layouts elsewhere.
  • Preserve the existing framework, theme tokens, icon package, and fonts unless changing them is part of the brief. Confirm dependencies before importing them.
  • Keep interactive state in the appropriate client boundary. Server components can fetch and compose data; they need not be reduced to static markup.
  • Design loading, empty, error, disabled, focus, and success states for the actual interactions. Never fabricate customer claims, testimonials, or production metrics.
  • Use responsive grids and content-driven breakpoints. Preserve reading and tab order, allow text scaling, and verify localized copy at phone and laptop widths.
  • Motion should clarify state or support the visual concept. CSS is sufficient for many interactions; use an existing animation library for complex choreography. Clean up effects, respect reduced motion, and keep content usable without animation.

Prefer one coherent visual direction over combining conflicting taste presets. Use source assets, generated artwork when useful, or clearly marked placeholders. Stop iterating when the requested surface is implemented and its material usability and visual issues are resolved; report any unavailable runtime checks honestly.

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.
