## What it does

The skill handles the boring parts of a Netlify deploy: build command, publish directory, SSR and edge adapters, SPA redirects. It ships per-framework guides — `references/astro.md`, `references/nextjs.md`, `references/nuxt.md`, `references/sveltekit.md`, `references/tanstack.md`, `references/vite.md` — and the agent reads the one that matches your stack instead of guessing.

Env vars get their own section. Values are injected at build time, so editing a var in the UI or CLI does nothing until a new build runs. Secrets must never sit behind a client prefix (`VITE_`, `NEXT_PUBLIC_`, `PUBLIC_`, `NUXT_PUBLIC_`, `REACT_APP_`, `GATSBY_`, `VUE_APP_`) because those get inlined into the browser bundle. Runtime access needs both Functions and Builds scope, and functions cannot read `netlify.toml` at runtime.

There is a build settings table covering everything from Angular and Astro to SvelteKit and TanStack Start. Local emulation of Netlify primitives runs through Vite plugins such as `@netlify/vite-plugin` and `@netlify/nuxt`, but Gatsby, Angular SSR and frameworks without a Vite plugin still need `netlify dev`. One trap worth knowing: if `[dev]` sets both a custom `command` and a `targetPort`, you must add `framework = "#custom"` or the detector silently ignores your command. Another: when you adopt an SSR adapter, drop the SPA catch-all `/* /index.html 200` — it keeps serving static `index.html` for SSR pages and API routes.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add netlify/context-and-tools --skill netlify-frameworks -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add netlify/context-and-tools --skill netlify-frameworks -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add netlify/context-and-tools --skill netlify-frameworks -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install netlify/context-and-tools netlify-frameworks
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add netlify/context-and-tools --skill netlify-frameworks -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/netlify/context-and-tools --path skills/netlify-frameworks
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add netlify/context-and-tools --skill netlify-frameworks -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/netlify/context-and-tools/tree/HEAD/skills/netlify-frameworks/SKILL.md

## When to use it
- set the build command and publish directory for your framework
- wire up an SSR adapter without breaking existing routes
- find out why an env var change never reaches the live site
- fix SPA redirects after switching to server rendering
- run functions and edge functions locally without the Netlify CLI

## Example prompts
- Set up an Astro deploy on Netlify: build command, publish directory and the SSR adapter
- My NEXT_PUBLIC_ var won't update after I edited it in the UI — what's going on?
- I moved SvelteKit to SSR but pages still come back static. Check the redirects

name: netlify-frameworks
description: Deploy and configure web frameworks on Netlify — build settings and SSR/edge adapters plus local platform emulation and env vars. Use when setting up or fixing a framework deploy (Next.js / Astro / Nuxt / SvelteKit / Remix / React Router / TanStack Start / SolidStart / Gatsby / Angular / Vite / Express / Hydrogen / Hugo / Eleventy / Vue / React), adding SSR or edge functions or middleware wired to Netlify context, fixing SPA redirect and catch-all rules, setting a build command or publish directory, or debugging "why isn't my env var updating" and framework build failures.

Route framework-specific deep work to the guides in this skill: `references/astro.md`, `references/nextjs.md`, `references/nuxt.md`, `references/sveltekit.md`, `references/tanstack.md`, `references/vite.md`.

## Env vars: modern rules (read first)

Env values are injected **at build time**. Any change (client- or server-side) requires a **redeploy** — editing a var in the UI/CLI does NOT reach the live site or already-deployed functions until a new build runs.

**Never use a client prefix for secrets.** Client-prefixed vars are inlined into the browser bundle:
`VITE_`, `NEXT_PUBLIC_`, `PUBLIC_`, `NUXT_PUBLIC_`, `REACT_APP_`, `GATSBY_`, `VUE_APP_`.

Client-embed prefixes by framework: CRA `REACT_APP_`, Gatsby `GATSBY_`, Next `NEXT_PUBLIC_`, Nuxt `NUXT_ENV_`, Vue CLI `VUE_APP_`.

**Scopes:** build-time access needs **Builds** scope; SSR/DSG runtime access needs **both Functions and Builds**. `netlify.toml` is read only during build — functions cannot read it at runtime; set runtime vars in UI/CLI/API.

Netlify build variables can't be used as values in the UI or `netlify.toml` env sections. Set them inline before the build command:
```toml
[build]
  command = "REACT_APP_CONTEXT=$CONTEXT npm run build"
```

## SPA redirects and the SSR catch-all footgun

SPAs (React, Vue CLI, Vite, Nuxt in SPA mode) need a rewrite to serve `index.html` for `pushState`:
```
/* /index.html 200
```
