Replicate Claude Design Capabilities Without Limits
Huashu Design is an open-source GitHub repo that ports Claude Design's system prompts and design philosophies into a single loadable skill for Claude Code, CodeCS, or any coding agent. It accesses 20 deep-dive Markdown files covering slide decks, design styles, animation best practices—effectively bundling 20 mini-skills. The skill pulls from components, media assets, and an executable toolchain: converts HTML to MP4, uses Playwright to validate designs in browsers, generates variations, and supports full tweaking. Run it on Pro, 5x, or 20x plans without Claude Design's weekly limits, which hit in under an hour even on $200/month 20x subscriptions.
To use: Load the skill in Claude Code and prompt like "Use the design skill to create a landing page for product. Ask questions first." It queries for product details, target buyer, vibe, sections, variations, and copy—mirroring Claude Design but text-based.
Head-to-Head Tests Show Near-Parity Outputs
Test 1: Landing page from scratch (Lighthouse SaaS analytics bench for solo devs). Huashu generated three variants (Ledger/editorial, Terminal, Paper) in one view or separate pages, using ~170k tokens (<<1% weekly usage on 20x). Claude Design matched variants (Terminal, Editorial, Spatial) but consumed 15% usage. Tweaks comparable: Huashu offers presets, display family, dark mode, accents, layout density, trust strip toggles—one prompt adds more. Claude Design edges with clickable edits, color pickers, typography tweaks via graphic interface.
Test 2: Landing page from design system (Agentic OS dashboard). Provided directory with fonts, colors, spacing, components. Huashu recreated matching aesthetic (sprite logo, ticker, dashboard embed) in 11 minutes/70k tokens. Claude Design did it in 3 minutes/10% usage, slightly better dashboard integration. Both maintained family consistency.
Test 3: Slide deck on Lighthouse using same system. Huashu produced cohesive deck (cover, features, scrolling text) with minor overlaps fixable in one prompt. Claude Design matched in 2 minutes/6% usage, minor sprite stretch. All tests: Huashu competes closely, handles web/mobile prototypes, motion design, infographics.
Usage Wins Outweigh Speed and Interface Gaps
Huashu trades Claude Design's 3-11x speed and graphical tools (draw/edit/comment, team sharing) for infinite runs—e.g., full landing page + tweaks used 170k tokens vs. 15-30% Claude Design quota. Ideal for heavy iteration without limits; pre-superior for macro variants/tweaking via prompts. Not a full replacement—lacks pixel-perfect edits—but leaps beyond basic frontend skills.
