At a glance

WebGL-style fluid displacement background with a quote overlay, suited to video intros, landing heroes, or posters.

  • Works in 3 steps: CSS 多层 radial-gradient 错位呼吸 (最稳, 默认推荐) → Canvas + simple perlin noise (中阶) → WebGL fragment shader (高阶, 慎用)
  • Tasks that involve 3D graphics and WebGL
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Frame Liquid Bg Hero is an agent skill from nexu-io/open-design. WebGL-style fluid displacement background with a quote overlay, suited to video intros, landing heroes, or posters.

Its SKILL.md is about 790 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `example.md`).

It sits in Game Development, covering 3D graphics and WebGL. The repository describes itself as: 🎨 Best DeepSeek Harness Design Plugin. The open-source Claude Design alternative. 🖥️ Local-first desktop app. 🖼️ Your coding agent becomes the design engine: prototypes… The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve 3D graphics and WebGL

Example prompts

  • “/frame-liquid-bg-hero”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. CSS 多层 radial-gradient 错位呼吸 (最稳, 默认推荐)
  2. Canvas + simple perlin noise (中阶)
  3. WebGL fragment shader (高阶, 慎用)

What it can do on your machine

Read from SKILL.md and the folder at commit 17e2559. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Frame Liquid Bg Hero loads about 791 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 201 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~791

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

【模板: 流体背景 Hero】 【意图】可作为视频片头帧、SaaS landing 顶部 hero、海报底图。WebGL 流体感, 但用 CSS / canvas 退化绘制, 确保单文件可双击打开。Inspired by hyperframes vfx-liquid-background。

【画布】1920×1080 (横) 或 1080×1920 (竖), 二选一。背景占满。

【流体背景 — 3 种实现, 按用户偏好选】

  1. CSS 多层 radial-gradient 错位呼吸 (最稳, 默认推荐):
    • 3-5 个大椭圆 radial-gradient(...), 颜色取自调色板。
    • 每个椭圆套 @keyframes 平移 + scale + hue-rotate, 周期 8-14s, 错峰; 整个画面叠 mix-blend-mode: screen 或 overlay。
    • 顶层加 1 层 backdrop-filter: blur(80px) 让边缘更糊。
  2. Canvas + simple perlin noise (中阶):
    • 80 行 inline JS, 用 requestAnimationFrame 画 metaballs 或 simplex noise field。
    • 性能允许时启用, prefers-reduced-motion 时降回静态截图。
  3. WebGL fragment shader (高阶, 慎用):
    • 用 jsdelivr CDN 引 regl 或 inline plain WebGL。
    • shader 写 domain-warp noise; 单个 quad, 一个 uniform u_time。

【顶层文字层】

  • 居中或左下: 一句巨型金句 (5-7vw, 衬线或粗 sans), 字体: Source Serif Pro / Inter Tight / Manrope Black。
  • 文字色用 paper white #fafaf8 或 ink, 取决于背景明暗; 加 mix-blend-mode: difference 让它在任何流体颜色上都可读。
  • 副标 (小 sans, opacity 0.7) 一行。
  • 底部可选 CTA chip 或 hairline + 元数据 row。

【调色 — 4 选 1, 不要彩虹】

  • 🌅 Solar Peach — #ffb18a + #f78b4c + #d97757, 暖橙桃。
  • 🌊 Ocean Aqua — #5ac8fa + #0a84ff + #1e3a8a, 海蓝。
  • 🌌 Aurora Violet — #a78bfa + #7c5cff + #1e1b4b, 极光紫。
  • 🌿 Forest Mint — #86efac + #34d399 + #065f46, 苔森林。

【设计细节】

  • 严禁: 多色彩虹 (>4 个色相)、PowerPoint 渐变、霓虹荧光叠加。
  • 字体: 中文用 Noto Serif SC (display) / Noto Sans SC (副标)。
  • 严禁外链图片; 全部 CSS + SVG + 可选 canvas。
  • 必须用用户提供的金句 / 标题; 如果用户输入是数据 → 提炼一句 ≤ 18 字的金句。
  • 单文件 HTML, 可被 prefers-reduced-motion 关动效。
