Effective HTML

简体中文

Focused agent skills for creating useful, self-contained HTML artifacts, from low-fidelity wireframes to working interactive prototypes.

Fat artifacts + fat context

Modern models can do a lot. Give them plenty of useful references and use artifacts to show what you mean. HTML can visualize almost anything, often more clearly than a wall of text. Your prompt can simply point to the artifacts, repositories, and folders that carry the context.

[!NOTE] You can use this repo without installing anything. Treat it as a reference first and an installable skill collection second. See the Effective HTML guide.

Skill references

The repo includes seven optional skills for pragmatic visual artifacts.

Skill	Use it for
html	Broad HTML requests, mixed artifacts, reports, explainers, presentations, landing pages, tools, and routing to a specialist
big-pics-little-words	Explain the current subject in HTML with large visuals and minimal text while preserving key details; copied from bro
design-artifact	Subject-specific creative direction for any HTML artifact without imposing a reusable house style
html-wireframe	Low-fidelity layout directions that test content, hierarchy, navigation, flows, and responsive structure
html-prototype	Working prototypes with realistic states, interaction, keyboard support, and responsive behavior
html-plan	Plans, roadmaps, rollouts, and implementation sequences that preserve source commitments
html-diagram	Architecture, sequence, process, state, hierarchy, timeline, and system diagrams

How the skills work

The skills separate creative freedom from reliability:

• Visual direction comes from the conversation, project, audience, and subject.
• design-artifact provides a reusable design process without prescribing a reusable look.
• Wireframes stay intentionally unfinished so reviewers focus on structure.
• Prototypes implement one credible flow and its relevant states.
• Plans preserve source commitments.
• Diagrams choose a visual model and rendering method that fit the relationship being explained.
• Every artifact is responsive, accessible, self-contained, and verified in a browser.

Detailed guidance lives only where it is needed. The broad html skill routes the work, design-artifact supplies optional creative direction, and specialist skills own fidelity and behavior. Each skill remains independently usable.
