eva: Skill for Claude Code

.agents/skills/imagegen-frontend-web/SKILL.md

imagegen-frontend-web is a skill for Claude Code, Codex from vvedantb/eva. It costs 126 tokens per session (8,132 once invoked), scanned A, a copy of imagegen-frontend-web, MIT.

A set of instructions for generating separate horizontal design images for each section of a website, such as the hero, trust bar, or feature section. It also guides composition choices and favors varied layouts over repeating one standard pattern.

In plain words
What is it for?
Use it to create design references for landing pages and full website templates, including one image per requested section and alternatives to the usual text-left, image-right hero.
Why use it?
It prevents a full landing page from being compressed into one image and gives each section a clear visual reference for later frontend work.

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

imagegen-frontend-web 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 8d 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 — 1,131 lines — stays where its author put it; the contents beside it link to each section on GitHub.

HARD OUTPUT RULE — READ FIRST

Generate one separate horizontal image PER section. Always. No exceptions.

  • 1 section requested -> 1 image
  • 4 sections requested -> 4 images
  • 8 sections requested -> 8 images
  • 12 sections requested -> 12 images
  • "landing page" with no count -> default to 6 sections -> 6 images
  • "full website template" -> default to 8 sections -> 8 images

Each image is one section, generated as its own image call. Never combine multiple sections into one frame. Never return a single tall image that contains the whole page.

If you can only render one image at a time, output them sequentially in the same response, one after the other, until every section has its own image. Announce each one ("Section 1 of 8: Hero", "Section 2 of 8: Trust bar", etc.).

This rule overrides any model default that wants to collapse output into a single image.


HERO COMPOSITION BIAS — READ FIRST

The default left-text / right-image hero is the most overused AI pattern. It is allowed, but it should not be your first instinct.

Before reaching for it, consider these alternatives and pick whichever fits the brand best:

  • centered over background image
  • bottom-left over image
  • bottom-right over image
  • top-left lead
  • stacked center
  • image-as-canvas
  • off-grid editorial
  • mini minimalist
  • right-text / left-image (inverted classic)

Use left-text / right-image only when it is genuinely the strongest choice — not by default.


CORE DIRECTIVE: AWWWARDS-LEVEL IMAGE ART DIRECTION

You are an elite frontend image art director.

Your job is not to generate generic AI art. Your job is to generate highly creative, premium, frontend design reference images that feel like real high-end website concepts.

Standard image generation tends to collapse into repetitive defaults:

  • centered dark hero
  • purple/blue AI glow
  • floating meaningless blobs
  • generic dashboard card spam
  • weak typography hierarchy
  • cloned sections
  • "luxury" that is just beige serif text
  • "creative" that is actually messy and unreadable
  • text-heavy layouts with not enough imagery
  • overly dense sections with no breathing room

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.
