## What it does

The skill walks the project in five phases. First the structure: does `webflow.json` exist with `library.name` and `library.components`, does the glob pattern match your component files, are `globals` and `bundleConfig` present. Then it checks that `@webflow/webflow-cli`, `@webflow/data-types` and `@webflow/react` are installed, and that every `.webflow.tsx` imports `declareComponent` from `@webflow/react`.

Component analysis comes next. It verifies `declareComponent` is called with the component and a config object, that each prop has a `name` and a `defaultValue`, and that the type is one of the 11 supported: Text, RichText, TextNode, Link, Image, Number, Boolean, Variant, Visibility, Slot, ID. It also scans for `window`, `document` and `localStorage` outside `useEffect`, and suggests `ssr: false` for purely interactive components.

Styling has a catch: site classes do not work in Shadow DOM, while CSS variables and inherited properties do. Tag selectors need `applyTagSelectors: true`. If a component uses slots together with `useContext`, the skill warns that parent and children in slots cannot share React Context, since each child renders in its own Shadow DOM. Styled-components, Emotion, MUI, Tailwind, Sass and Less each get their own setup check. Node.js 18+, React 18+ and TypeScript are required.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add webflow/webflow-skills --skill webflow-code-component:pre-deploy-check -a claude-code
```
```bash
npx skills add webflow/webflow-skills --skill pre-deploy-check -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/pre-deploy-check/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/pre-deploy-check/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add webflow/webflow-skills --skill pre-deploy-check -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/pre-deploy-check/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add webflow/webflow-skills --skill pre-deploy-check -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/pre-deploy-check/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install webflow/webflow-skills pre-deploy-check
```

2. **Manually: put the files in place**
- File: `.github/skills/pre-deploy-check/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add webflow/webflow-skills --skill pre-deploy-check -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/webflow/webflow-skills --path plugins/webflow-skills/skills/pre-deploy-check
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/pre-deploy-check/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add webflow/webflow-skills --skill pre-deploy-check -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/webflow/webflow-skills/tree/HEAD/plugins/webflow-skills/skills/pre-deploy-check/SKILL.md

## When to use it
- catch a broken glob pattern before publishing the library
- find props missing `name` or `defaultValue`
- spot `window` access outside `useEffect`
- check that the bundle stays under 50MB
- confirm the Shadow DOM decorator is wired for styled-components

## Example prompts
- check my components before deploy
- run pre-deploy-check on this project
- validate the components, I'm about to run `webflow library share`

# Build Validate

Validate code components before deployment to catch issues early.

## When to Use This Skill

**Use when:**
- User is about to deploy and wants to check for issues first
- Proactively before running `webflow library share`
- User asks to validate, check, or verify their components
- After making significant changes to components

**Do NOT use when:**
- Deployment already failed (use troubleshoot-deploy instead)
- Just building for local development
- Auditing code quality (use component-audit instead)

## Instructions

### Phase 1: Project Structure Check

1. **Verify webflow.json exists**:
   - Check for required fields (`library.name`, `library.components`)
   - Validate glob pattern matches component files — the recommended pattern is `"./src/**/*.webflow.@(js|jsx|mjs|ts|tsx)"` covering all supported extensions
   - Check `globals` path if specified — file must exist and be importable
   - Check `bundleConfig` path if specified — file must exist

2. **Check dependencies**:
   - Verify `@webflow/webflow-cli` installed
   - Verify `@webflow/data-types` installed
   - Verify `@webflow/react` installed
   - Check for version compatibility (check installed versions, don't assume specific versions)

3. **Verify component files**:
   - Find all `.webflow.tsx` / `.webflow.ts` files matching the glob pattern
   - Ensure matching React components exist
   - Check for orphaned definition files

4. **Validate imports in `.webflow.tsx` files**:
   - Must import `declareComponent` from `@webflow/react`
   - Must import `props` from `@webflow/data-types` (if props are defined)
   - Must import the actual React component being declared

### Phase 2: Component Analysis

5. **For each component, check**:
   - `declareComponent` is called with the component and a config object
   - `name` is provided in the config
```
