security: Remove vercel-deploy (data exfiltration), annotate LD_PRELOAD shims

Browse Source 
Security audit findings:
- CRITICAL: vercel-deploy uploaded entire project to external endpoint — REMOVED
- ANNOTATED: docx/pptx/xlsx soffice.py LD_PRELOAD shims — security warnings added
- README updated to 93 skills with full security audit section and Vue/Vite ecosystem

name: vercel-deploy
description: Deploy applications and websites to Vercel. Use this skill when the user requests deployment actions such as "Deploy my app", "Deploy this to production", "Create a preview deployment", "Deploy and give me the link", or "Push this live". No authentication required - returns preview URL and claimable deployment link.
metadata:
author: vercel
version: "1.0.0"
---
# Vercel Deploy
Deploy any project to Vercel instantly. No authentication required.
## How It Works
1. Packages your project into a tarball (excludes `node_modules` and `.git`)
2. Auto-detects framework from `package.json`
3. Uploads to deployment service
4. Returns **Preview URL** (live site) and **Claim URL** (transfer to your Vercel account)
## Usage
```bash
bash /mnt/skills/user/vercel-deploy/scripts/deploy.sh [path]
```
**Arguments:**
- `path` - Directory to deploy, or a `.tgz` file (defaults to current directory)
**Examples:**
```bash
# Deploy current directory
bash /mnt/skills/user/vercel-deploy/scripts/deploy.sh
# Deploy specific project
bash /mnt/skills/user/vercel-deploy/scripts/deploy.sh /path/to/project
# Deploy existing tarball
bash /mnt/skills/user/vercel-deploy/scripts/deploy.sh /path/to/project.tgz
```
## Output
```
Preparing deployment...
Detected framework: nextjs
Creating deployment package...
Deploying...
✓ Deployment successful!
Preview URL: https://skill-deploy-abc123.vercel.app
Claim URL: https://vercel.com/claim-deployment?code=...
```
The script also outputs JSON to stdout for programmatic use:
```json
{
"previewUrl": "https://skill-deploy-abc123.vercel.app",
"claimUrl": "https://vercel.com/claim-deployment?code=...",
"deploymentId": "dpl_...",
"projectId": "prj_..."
}
```
## Framework Detection
The script auto-detects frameworks from `package.json`. Supported frameworks include:
- **React**: Next.js, Gatsby, Create React App, Remix, React Router
- **Vue**: Nuxt, Vitepress, Vuepress, Gridsome
- **Svelte**: SvelteKit, Svelte, Sapper
- **Other Frontend**: Astro, Solid Start, Angular, Ember, Preact, Docusaurus
- **Backend**: Express, Hono, Fastify, NestJS, Elysia, h3, Nitro
- **Build Tools**: Vite, Parcel
- **And more**: Blitz, Hydrogen, RedwoodJS, Storybook, Sanity, etc.
For static HTML projects (no `package.json`), framework is set to `null`.
## Static HTML Projects
For projects without a `package.json`:
- If there's a single `.html` file not named `index.html`, it gets renamed automatically
- This ensures the page is served at the root URL (`/`)
## Present Results to User
Always show both URLs:
```
✓ Deployment successful!
Preview URL: https://skill-deploy-abc123.vercel.app
Claim URL: https://vercel.com/claim-deployment?code=...
View your site at the Preview URL.
To transfer this deployment to your Vercel account, visit the Claim URL.
```
## Troubleshooting
### Network Egress Error
If deployment fails due to network restrictions (common on claude.ai), tell the user:
```
Deployment failed due to network restrictions. To fix this:
1. Go to https://claude.ai/settings/capabilities
2. Add *.vercel.com to the allowed domains
3. Try deploying again
```
