Agent Skills

A curated collection of agent skills for designers and builders using Codex, Claude, Cursor, and other AI coding agents to build rich user interfaces, playable games, frontend systems, agent loops, automations, and reusable workflows.

Use these skills with Codex, Claude Design, Aura Build, Lovable, and the rest of your agent stack to turn references into prompts, generate detailed landing pages, build playable Three.js systems, and create reusable implementation workflows.

Start with the flagship web-design workflow:

1. Video to Super Prompt Turns a screen recording of a design, landing page, or animation into a super detailed prompt that Fable 5 can use to one-shot HTML. 2. HTML to Interaction Prompts Turns an existing HTML page, like an Aura Build page, into reusable prompts for one section, one animation, one button, one hover state, or one WebGL effect. 3. Stitched Full Page Capture Captures the entire landing page instead of only the hero, giving your agent a full-page reference for structure, pacing, and visual hierarchy. 4. Daily UI Inspiration Combines browsing, capture, reference study, and prompt generation into a useful agent loop that turns strong landing pages into detailed prompt packs.

These are portable agent skill folders: concise SKILL.md playbooks with optional references, articles, scripts, and assets. The goal is simple: turn good prompts, workflows, style systems, capture recipes, and debugging habits into versioned files an agent can load and follow.

Portable by default. Each skill should work for any user, repo, or workspace unless the user supplies project-specific context through local agent instructions.

Browse all runnable demos and recreation prompts.

Explore the 3D rendering skills for ultra-realistic water, virtual tours, sky rays, sky backgrounds, falling leaves, four seasons, detailed textures and models, and Retina rendering at 200%.

Use these skills when you want:

• repeatable design direction
• reusable game architecture and gameplay QA
• procedural implementation steps
• copy/paste snippets
• common pitfalls and guardrails
• reusable workflows instead of one-off chat answers

Agent support

The format is intentionally plain Markdown and folder-based.

• Codex: load the relevant SKILL.md before acting. Repo behavior belongs in AGENTS.md; browser work in this repo should use the Codex browser.
• Claude Code: reference the relevant skill from CLAUDE.md, copy it into a Claude skills setup, or open the SKILL.md directly as working context.
• Cursor: point Cursor rules or chat context at the specific skill folder. Keep reusable snippets, constraints, and defaults easy to paste.
• Other agents: use the same contract: read the narrowest matching skill first, then follow its steps and linked references.

Philosophy

1) Prompts are assets

If it’s good once, it should be reusable.

• store prompts as files
• version them
• build libraries + stylecards

2) Specs beat vibes

The fastest way to consistent output is:

• clear constraints
• clear hierarchy
• “change 1–2 things only” iteration

3) References beat paragraphs

Screenshots and examples carry:

• fonts, spacing, colors
• layout rhythm
• icon style

4) Skills are operating procedures

Good skills tell the agent exactly when to use them, what to do first, what defaults to apply, and what mistakes to avoid.

Folder contract:

agent-skills///
  SKILL.md            # required: frontmatter + workflow
  REFERENCES.md       # optional: links only
  ARTICLE.md          # optional: long-form explanation
  assets/             # optional: images, templates, examples
  scripts/            # optional: helper scripts
  demo/               # optional: visual or interaction proof
    index.html         # standalone HTML, CSS, and JavaScript
    PROMPT.md          # exact recreation and remix prompts
    assets/            # local demo assets when required

Conventions:

• SKILL.md is the skill an agent loads and follows.
• REFERENCES.md is links only. Keep SKILL.md lean.
• Visual and interaction skills may include a portable demo/index.html and demo/PROMPT.md.
• Workflow skills may include fictional demo/input.md and demo/expected-output.md handoffs when they materially improve proof.
• Keep skills procedural (steps, patterns, guardrails), not encyclopedic.
• Prefer explicit triggers: "Use when..." beats vague descriptions.
• Prefer defaults: durations, spacing, hierarchy, commands, and acceptance checks.

• workflow-score-to-target - score work out of 10 on an anchored rubric, judge it independently, and improve round by round until every item hits the target.
• workflow-ship-change - ship every change: screenshots, changelog, tests, own files only, fast-forward push, draft-then-live publish, measured sizes and a 50 MB stop.
• workflow-threads-manager - oversee many agent threads on one repo: what merged, what's live, what's missing from the changelog, what to archive, what got cut off.

How to add a new skill (workflow)

1) Create a folder:

• agent-skills///

2) Add SKILL.md:

• frontmatter: name, description
• content: when to use, workflow, pitfalls, recipes, what to ask

3) Add a portable demo when visual or interaction proof is useful:

• demo/index.html with inline CSS and JavaScript
• demo/PROMPT.md with minimal, recreation, and remix prompts
• local files under demo/assets/

4) (Optional) add REFERENCES.md:

• doc links only

5) Test the skill contract:

• clear trigger
• concrete workflow
• reusable snippets or commands
• pitfalls and acceptance checks
• no secrets or private client info

6) Commit:

• small commits per skill
• clear message, usually Add skill or Update skill

---

Writing style

• Write like Meng To: skimmable, practical, confident.
• Prefer constraints and defaults.
• Avoid fluff.
• Keep long explanations in ARTICLE.md, not SKILL.md.
• Keep references in REFERENCES.md, not the workflow.

---

Maintenance ideas

• Keep category README files current as the library grows.
• Add install notes for Codex, Claude Code, and Cursor once the preferred setup is stable.
• Add lightweight validation for required frontmatter.
• Keep imported skills portable: no secrets, no private paths, no hidden account assumptions.
