# Claude Code Skills

A collection of reusable [Claude Code](https://docs.anthropic.com/en/docs/claude-code) skills (slash commands) that extend what Claude can do from your terminal.

## Skills

### `/create-marp-deck` — Build Marp Slide Decks

A thinking partner for presentations, powered by [Marp](https://marp.app/) (Markdown Presentation Ecosystem).

```
/create-marp-deck API rate limiting
```

The skill starts by **talking through the presentation with you** - asking about the goal, audience, key points, data to include, and constraints. This helps you figure out the story and structure before a single slide exists. Then it generates a first draft you can iterate on.

What you get:
- A structured first draft with a narrative arc you can react to and reshape
- Styled Marp Markdown with gradient section dividers, breadcrumb navigation, and consistent formatting
- Automatic export to HTML and PPTX
- A **mobile-friendly web build** for decks you share as a link (see below)
- Opinionated conventions: one idea per slide, 3-5 bullet max, color-coded sections

See the [full skill file](https://github.com/omerr/claude-skills/blob/HEAD/commands/create-marp-deck.md) for all conventions and the CSS template.

#### Mobile-friendly sharing

Marp's HTML export renders every slide as a fixed 1280×720 stage, so on a phone the whole slide scales to ~30% and body text lands at ~7px — technically responsive, practically unreadable.

For decks shared as a link, the skill builds two files: `index.html` stays the real slideshow (arrow keys, fullscreen) for desktop, while phones are redirected to a `mobile.html` that reflows the deck's **content** into a normal responsive document — real text at phone size, one card per slide, keeping the deck's own section-divider gradients. Generated by [`scripts/marp-mobile.py`](https://github.com/omerr/claude-skills/blob/HEAD/skills/create-marp-deck/scripts/marp-mobile.py).

**Read the article**: [Stop Staring at a Blank Deck](https://medium.com/@Omer_Rosenbaum/stop-staring-at-a-blank-deck-how-i-use-claude-code-marp-to-think-through-presentations-74bb95ec67d3) | [View the deck](https://omerr.github.io/claude-skills/presentations/claude-code-marp/)

**Requires**: `npm install -g @marp-team/marp-cli` (or uses `npx` as fallback). The mobile build additionally needs `pip install markdown-it-py`.

### `/cr` — Code Review

Multi-pass code review for the current branch's open PR.

```
/cr
```

Performs 4 iterative passes:
1. **Bug hunting** — logic errors, null handling, race conditions, security issues
2. **Validation** — confirms findings, removes false positives
3. **Code smells** — duplication, complexity, naming, dead code
4. **Final sweep** — edge cases, integration issues, missing tests

Outputs findings categorized by severity (critical / warning / nit) with file paths and line numbers.

## Installation

### Option 1: Install via skills.sh (recommended)

Works with Claude Code, Cursor, GitHub Copilot, and [other AI agents](https://skills.sh):

```bash
npx skills add Omerr/claude-skills
```

### Option 2: Clone and symlink

```bash
git clone https://github.com/Omerr/claude-skills.git ~/claude-skills

ln -s ~/claude-skills/commands/create-marp-deck.md ~/.claude/commands/
ln -s ~/claude-skills/commands/cr.md ~/.claude/commands/
```

### Option 3: Copy individual files

```bash
cp commands/create-marp-deck.md ~/.claude/commands/
cp commands/cr.md ~/.claude/commands/
```

### Option 4: Project-level

Copy into a specific project's `.claude/` directory to scope them to that repo:

```bash
cp commands/*.md your-project/.claude/commands/
```

## Customization

These skills are meant to be forked and adapted. Some things you might want to change:

- **`create-marp-deck.md`** — Swap the color palette, adjust font sizes, add your own slide structure conventions, modify the interview questions
- **`cr.md`** — Add project-specific review criteria or coding standards

## How Claude Code Skills Work

Skills live in `~/.claude/commands/` (global) or `.claude/commands/` (per-project). When you type `/` in Claude Code, your skills appear as available slash commands.
