## What it does

Under the hood it talks to the Preline MCP server, which exposes six tools returning integration-ready HTML, CSS and JS. The agent reaches for them when you mention preline or ask for a Tailwind CSS component from the library.

Slugs are never guessed. The skill discovers exact kebab-case identifiers through `components_list` or `blocks_categories` first, fetches a single component or block, reads the target file, and only then inserts. One item per round: integrate it fully, then move on. Composite requests such as a dashboard or a settings page get decomposed into a tree of containers and leaf components, assembled outermost-first.

When a request is vague, the skill shows the catalog categories with their descriptions and asks you to pick instead of guessing. Clarifying questions come in English until you write in another language. It earns its place if your project already runs on Tailwind and you would rather not copy markup out of the docs by hand.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add htmlstreamofficial/preline --skill preline-mcp -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add htmlstreamofficial/preline --skill preline-mcp -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add htmlstreamofficial/preline --skill preline-mcp -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install htmlstreamofficial/preline preline-mcp
```

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

```bash
npx skills add htmlstreamofficial/preline --skill preline-mcp -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/htmlstreamofficial/preline --path skills/preline-mcp
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add htmlstreamofficial/preline --skill preline-mcp -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/htmlstreamofficial/preline/tree/HEAD/skills/preline-mcp/SKILL.md

## When to use it
- drop a ready Preline component into an existing HTML file
- build a page out of blocks instead of loose markup
- find the right block by browsing catalog categories
- break a dashboard request into containers and leaf components
- get HTML, CSS and JS in one response without opening the docs

## Example prompts
- add a preline accordion component to index.html
- build a settings page from Preline blocks
- I need the Preline hero block with tabs

name: preline-mcp
description: Add, integrate, or build Preline UI components and blocks into HTML files via the Preline MCP server. Use when the user mentions "preline", says "/preline", asks to add a UI component, or requests a Preline block (a ready-made page section) using Preline UI.

# Preline MCP

## Intent

Use this skill to integrate Preline UI components and blocks into HTML files via the Preline MCP server. The server exposes 6 tools that return integration-ready HTML, CSS, and JS.

Activate when:
- User says "preline", "add preline", "/preline", "use preline"
- User asks for a Tailwind CSS component from the Preline library
- User asks for a block (ready-made page section) or a starter page

## Defaults

- **Never guess slugs.** All section, component, and category identifiers are exact kebab-case strings. Always discover them via `components_list` or `blocks_categories` first.
- **One at a time.** Retrieve one component or block, integrate it fully, then move to the next.
- **Always read the target file** before inserting anything.
- Call `components_list({ section: "<inferred-slug>" })` when the component type is known - this keeps the response small. Omit section only when unsure.

## Decision: Component vs Block

| User says | Use |
|---|---|
| "component" / "components" | Component workflow |
| "block" / "blocks" (or "example" / "examples") | Block workflow |
| Ambiguous | Use judgment; blocks give more complete results |

## Clarifying Vague Requests

Ask the user to pick instead of guessing in either of these cases:

- **Abstract request.** Too abstract to confidently map onto one category/section, let alone one block/component - e.g. "give me something for a pricing page", "I need a nice form", "show me a dashboard example". Start at step 1 below.
- **Tied candidates.** The request is concrete enough to reach a single category/section, but `blocks_in_category` / `components_list({ section })` still leaves 2+ candidates whose titles + descriptions satisfy every criterion the request named about equally well (same layout/feature/style class), with nothing in the request to break the tie. Skip straight to step 3 below with just the tied candidates.

If exactly one candidate matches everything the request names ("a basic accordion", "the SaaS hero with tabs"), skip straight to the normal workflow - don't interrogate the user for things you can already resolve, and don't ask just to be safe when one option is clearly the best fit.

All clarifying questions and lists are in **English by default** - switch to the user's language only once they write to you in it.

**Blocks:**
