# cloudinary-next

Guides your agent through Next.js code that uses Cloudinary: images, video, uploads, OG cards. Handy when the server/client boundary or signed uploads get messy.

## What it does

The skill kicks in when a Next.js project uses `next-cloudinary` or the Node SDK v2. The agent classifies the task first: render a transformed image in JSX, build a URL string, embed a video player, upload from the browser or the server, delete an asset, build an overlay, or generate a social card. Then it loads only the reference file that task needs instead of the whole set.

Hard rules come before any detailed reference. Components and URL helpers come from `next-cloudinary`: `CldImage`, `CldVideoPlayer`, `CldUploadWidget`, `CldUploadButton`, `CldOgImage`, `getCldImageUrl`, `getCldOgImageUrl`, `getCldVideoUrl`. The Node SDK v2 (`import { v2 as cloudinary } from 'cloudinary'`) stays server-side. `CLOUDINARY_API_SECRET` never reaches the browser, and `NEXT_PUBLIC_CLOUDINARY_API_SECRET` is off the table. Upload widgets and the player sit behind `'use client'`, while Server Actions and route handlers that import `cloudinary` must run on the Node.js runtime.

Separate references cover signed uploads, deletes, overlays, responsive images, TypeScript narrowing, and common errors. Deletes take a public ID, not a delivery URL, and videos or raw assets need `resource_type`. When a detail is version-sensitive, the skill tells the agent to check the official docs rather than trust memory. That is the part worth having: fewer invented prop names in your diff.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add cloudinary-devs/skills --skill cloudinary-next -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add cloudinary-devs/skills --skill cloudinary-next -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add cloudinary-devs/skills --skill cloudinary-next -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install cloudinary-devs/skills cloudinary-next
```

2. **Manually: put the files in place**
- File: `.github/skills/cloudinary-next/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add cloudinary-devs/skills --skill cloudinary-next -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/cloudinary-devs/skills --path skills/frameworks/cloudinary-next
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add cloudinary-devs/skills --skill cloudinary-next -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/cloudinary-devs/skills/tree/HEAD/skills/frameworks/cloudinary-next/SKILL.md

## When to use it
- render a transformed Cloudinary image in JSX
- build an image or video URL as a string
- set up a signed upload in the App Router
- delete an asset by public ID with cache invalidation
- fix import and server/client boundary errors

## Example prompts
- Add CldImage to the product page with responsive sizes and a 4:3 crop
- Write a route handler for signed uploads in the App Router
- Review this component: is CLOUDINARY_API_SECRET leaking to the client?

# Cloudinary Next

## Purpose

Use this skill to help developers build, debug, or review Next.js projects that integrate Cloudinary through `next-cloudinary` and, for server-only operations, the Cloudinary Node SDK v2.

This skill is organized for progressive loading. Do not load every reference file by default. Start with the workflow below, then load only the reference files needed for the user's task.

## Core workflow

1. Classify the user's goal before writing code:
   - render a transformed Cloudinary image in JSX
   - generate a Cloudinary URL string
   - embed a video player
   - upload from the browser
   - perform a signed upload
   - upload from the server
   - delete an asset
   - build an overlay or text overlay
   - generate an OG/social image
   - fix TypeScript, environment, import, runtime, or upload errors
   - review an existing implementation
2. Load the relevant reference file from the map below.
3. Apply the non-negotiable rules in this `SKILL.md` before using any detailed reference.
4. For code review or debugging, load `references/troubleshooting.md` plus the task-specific reference.
5. When a detail is version-sensitive or not covered here, consult the official documentation linked in `references/official-docs.md` and prefer official prop names and event names over memory.

## Non-negotiable rules

- Use `next-cloudinary` for Next.js components and URL helpers: `CldImage`, `CldVideoPlayer`, `CldUploadWidget`, `CldUploadButton`, `CldOgImage`, `getCldImageUrl`, `getCldOgImageUrl`, and `getCldVideoUrl`.
- Use the Cloudinary Node SDK v2 only for server-side operations: `import { v2 as cloudinary } from 'cloudinary'`.
- Never expose `CLOUDINARY_API_SECRET` to the browser. Never create `NEXT_PUBLIC_CLOUDINARY_API_SECRET`.
```
