eva: Skill for Claude Code

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

stitch-design-taste is a skill for Claude Code, Codex from vvedantb/eva. It costs 50 tokens per session (2,743 once invoked), scanned A, a copy of stitch-design-taste, MIT.

A design-system guide generator for Google Stitch, a tool that creates user-interface screens from descriptions. It produces a DESIGN.md file containing visual and interaction rules.

In plain words
What is it for?
Use it to define a shared visual direction for new Stitch screens, including color values, font choices, component behavior, and rules against generic-looking designs.
Why use it?
It gives Stitch consistent guidance about typography, colors, layouts, motion, and performance instead of leaving those choices vague.

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

This is vvedantb/eva's own configuration. It tells Claude Code and Codex how to work on eva 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 eva 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

stitch-design-taste 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 11d 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.

Stitch Design Taste — Semantic Design System Skill

Overview

This skill generates DESIGN.md files optimized for Google Stitch screen generation. It translates the battle-tested anti-slop frontend engineering directives into Stitch's native semantic design language — descriptive, natural-language rules paired with precise values that Stitch's AI agent can interpret to produce premium, non-generic interfaces.

The generated DESIGN.md serves as the single source of truth for prompting Stitch to generate new screens that align with a curated, high-agency design language. Stitch interprets design through "Visual Descriptions" supported by specific color values, typography specs, and component behaviors.

Prerequisites

  • Access to Google Stitch via labs.google/stitch
  • Optionally: Stitch MCP Server for programmatic integration with Cursor, Antigravity, or Gemini CLI

The Goal

Generate a DESIGN.md file that encodes:

  1. Visual atmosphere — the mood, density, and design philosophy
  2. Color calibration — neutrals, accents, and banned patterns with hex codes
  3. Typographic architecture — font stacks, scale hierarchy, and anti-patterns
  4. Component behaviors — buttons, cards, inputs with interaction states
  5. Layout principles — grid systems, spacing philosophy, responsive strategy
  6. Motion philosophy — animation engine specs, spring physics, perpetual micro-interactions
  7. Anti-patterns — explicit list of banned AI design clichés

Analysis & Synthesis Instructions

1. Define the Atmosphere

Evaluate the target project's intent. Use evocative adjectives from the taste spectrum:

  • Density: "Art Gallery Airy" (1–3) → "Daily App Balanced" (4–7) → "Cockpit Dense" (8–10)
  • Variance: "Predictable Symmetric" (1–3) → "Offset Asymmetric" (4–7) → "Artsy Chaotic" (8–10)
  • Motion: "Static Restrained" (1–3) → "Fluid CSS" (4–7) → "Cinematic Choreography" (8–10)

Default baseline: Variance 8, Motion 6, Density 4. Adapt dynamically based on user's vibe description.

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.
