What is stitch-shadcn-ui?

A workflow for applying Google Stitch design direction to a React project that uses shadcn/ui, a library of reusable interface components. It maps Stitch designs to existing components and project conventions.

Use it to inspect a shadcn/ui React project, add or reuse components such as buttons, forms, dialogs, tables, and tabs, and apply Stitch themes and layouts.

It helps keep generated interface pieces consistent with the project's component setup instead of creating disconnected UI code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00034	$0.01231
Opus 5	$0.00017	$0.00616
Sonnet 5	$0.00007	$0.00246
Haiku 4.5	$0.00003	$0.00123

Security

Grade A, and why

stitch-shadcn-ui scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/verify-setup.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Stitch shadcn/ui Integration

This skill is a catalog-normalized import from https://github.com/google-labs-code/stitch-skills at commit 7b53207b94e62911777d53d4238b5f8c88c2b519, source path plugins/stitch-build/skills/shadcn-ui. The upstream control file was corrected for this workspace: the verified Stitch MCP surface here is design-system oriented, so screen lookup, screen generation, and screen editing tools must be used only when the current host explicitly exposes them.

When to Use This Skill

Use when a Stitch design should be implemented with shadcn/ui components.
The task involves Google Stitch project IDs, .stitch/ artifacts, DESIGN.md files, Stitch exports, or Stitch-specific validation.
The broader stitch-design router points here as the narrowest workflow.

Workflow

Inspect for components.json, Tailwind config, path aliases, and existing components/ui patterns.
Use npx shadcn@latest init or npx shadcn@latest add <component> unless a verified shadcn MCP tool exists.
Map Stitch components to shadcn primitives such as Button, Card, Dialog, Sheet, Tabs, Table, Command, Form, and Select.
Keep components/ui close to generated source; build project-specific wrappers elsewhere.
Update CSS variables and Tailwind tokens to match DESIGN.md.
Verify light/dark themes, keyboard behavior, ARIA attributes, and responsive layouts.

Local Assets

examples/, resources/, references/, or reference/ are upstream support material when present. Treat SKILL.md as the source of truth if a support file mentions an unavailable MCP tool.
scripts/ are optional helpers. On Windows, prefer PowerShell or Node equivalents unless Git Bash or WSL is actually available.
Keep generated .stitch/ files out of commits unless the user explicitly wants them as durable examples.

Corrected Stitch MCP Surface

Verified in this workspace on 2026-06-15: create_project, upload_design_md, create_design_system_from_design_md, list_design_systems, and apply_design_system. This 2026-07-29 source refresh did not re-verify a broader live MCP surface. Do not claim list_projects, list_screens, get_project, get_screen, generate_screen_from_text, edit_screens, or generate_variants were used unless the current host exposes those exact tools in the active tool list.

What ships with it

10 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
