## 🔄 Updating

Skills under [Based On](#-based-on) drift as their upstreams change. To refresh one: fetch the
upstream folder, `diff` it against the local copy, and copy over the changed content files — but
keep the local `SKILL.md` frontmatter, since `name`/`description` and cross-skill references are
often customized. Skip a blind `npx skills update`: there is no lock file and some folders are
renamed from upstream.

## 📥 Installation

Copy or symlink skills to:

- **Claude Code**: `~/.claude/skills/` (global) or `.claude/skills/` (project)
- **Other agents** (Codex, Windsurf, Cursor): `~/.agents/skills/` or `.agents/skills/`

## 🔧 MCP Servers

Recommended MCP servers that pair with these skills:

```json
{
  "mcpServers": {
    "next-devtools": {
      "command": "npx",
      "args": ["-y", "next-devtools-mcp@latest"]
    },
    "chrome-devtools": {
      "command": "npx",
      "args": ["chrome-devtools-mcp@latest"]
    },
    "ai-elements": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://registry.ai-sdk.dev/api/mcp"]
    }
  }
}
```

This repo's own [`.mcp.json`](.mcp.json) already wires up `next-devtools` and `ai-elements`; `chrome-devtools` is optional and shown here for reference.

- [Next.js DevTools MCP](https://nextjs.org/docs/app/guides/mcp) — pairs with `next-best-practices`, `e2e-tester`
- [Chrome DevTools MCP](https://github.com/ChromeDevTools/chrome-devtools-mcp) — pairs with `chrome-devtools`, `go`, `e2e-tester`. Install via CLI: `claude mcp add chrome-devtools --scope user npx chrome-devtools-mcp@latest`
- AI Elements registry MCP — pairs with `ai-elements`, `ai-app`, `nextjs-chatbot`
