Together AI
A Claude Code, Cursor, and Codex design skill that generates UI that refuses to look AI-generated via 57 slop-test gates.
Key features
- Twenty Curated Themes: A catalog of macrostructures and design fingerprints so different briefs produce visibly different sites.
- Fifty-Seven Slop-Test Gates: A rules engine that rejects on-distribution AI defaults and forces the output through a pre-emit self-critique.
- Four Verbs: default (build), audit (score existing code), redesign (rebuild with a different fingerprint), and study (extract DNA from an admired design without cloning).
- Custom Mode: When a brief carries creative intent no catalog theme fits, Hallmark designs from scratch with a bespoke palette, type, and layout while still running the 57 gates.
- Self-Contained HTML + CSS Output: Every generated page is standalone HTML/CSS stamped with its macrostructure in a CSS comment for easy hand-off.
- Portable Design.md Handoff: The study verb can emit a design.md so other AI tools can reuse the extracted macrostructure, type pairing, and colors.
- Multi-Agent Install: Drops into Claude Code (~/.claude/skills/hallmark/), Cursor (.cursor/rules/hallmark.md), or Codex with a single copy of SKILL.md + references/.
Best for
- Marketing Sites That Don't Look AI-Made: Founders and designers use Hallmark to generate landing pages with distinct visual identities per brief.
- Auditing Existing UI: Score an existing codebase against the anti-pattern list to get a punch list of AI-looking design choices to fix.
- Redesign With Same Copy: Preserve copy, information architecture, and brand while rebuilding the page with a different macrostructure and fingerprint.
- Studying a Reference Design: Extract macrostructure, type pairing, and color anchor from a design you admire without pixel-cloning or reusing paid templates.
- Portable Design Handoff: Export a design.md that other AI coding agents can consume so design intent survives across tools.
- In-Agent Design Workflow: Developers who live inside Claude Code or Cursor generate production-ready HTML+CSS without leaving the terminal.

stitch-skills
Google Labs Code
Open-source collection of agent skills and plugins for Google Stitch that plug into Codex, Claude Code, Cursor, and Gemini CLI.
Key features
- Cross-Agent Plugin Bundles: Ships stitch-design, stitch-build, and stitch-utilities as marketplace plugins that install into Codex, Claude Code, Cursor, Antigravity, or Gemini CLI.
- Code to Design: Convert frontend code (React, Vue, etc.) into a Stitch design by extracting HTML, applying the design system, and uploading it to a Stitch project.
- Generate Design: Create new screens from text or images, edit existing screens, and produce dark-mode or high-density design variants.
- Design System Management: Upload a DESIGN.md and apply the theme across all screens in a Stitch project.
- Extract Design MD: Scan a codebase and generate a comprehensive DESIGN.md describing the design system directly from source.
- Static HTML Extraction: Capture self-contained static HTML from running web apps with CSS and images inlined for handoff.
- React / React Native / shadcn Codegen: Convert Stitch designs to production-ready React components, React Native code, or shadcn/ui-integrated apps.
- Remotion Walkthrough Videos: Generate video walkthroughs of a Stitch project with smooth transitions and zooming.
Best for
- Migrating a Codebase to a Design System: Upload an existing frontend into Stitch to run a design migration project with consistent tokens and theming.
- Rapid Screen Generation: Product teams generate mobile or web screens from short prompts and iterate on variants without leaving the coding agent.
- Code Handoff from Design: Convert Stitch screens into React or React Native components so engineers can consume the design in the target framework.
- Design System Extraction: Reverse-engineer a DESIGN.md from an existing repo to formalize implicit design tokens and share them across teams.
- Design Reviews and Walkthroughs: Automatically produce video walkthroughs of a project to share with stakeholders and reviewers.
- Agent-Native Workflows: Developers who live inside Claude Code, Cursor, or Codex install Stitch skills locally to drive design work from the same agent they use for coding.
