## What it does

The skill splits presentation building into two phases. First, the agent reads a brief, maps content to 18 slide types (such as `timeline`, `two_col`, or `stat`), and produces a JSON deck specification respecting strict character limits. Then, a local Node.js script renders `.pptx` slides via `pptxgenjs` or exports `.pdf` without spending extra tokens.

Visual decisions belong to the theme rather than model whims. Colors accept theme tokens or 6-character hex strings without `#`. Modifying existing PowerPoint decks is not supported: the tool only generates clean files from scratch.

Running this workflow requires Node.js to execute `generate-deck.js` and `export-pdf.mjs`. Complex data charts and interactive web presentations fall outside its scope.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add product-on-purpose/pm-skills --skill utility-slideshow-creator -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add product-on-purpose/pm-skills --skill utility-slideshow-creator -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add product-on-purpose/pm-skills --skill utility-slideshow-creator -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install product-on-purpose/pm-skills utility-slideshow-creator
```

2. **Manually: put the files in place**
- File: `.github/skills/utility-slideshow-creator/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add product-on-purpose/pm-skills --skill utility-slideshow-creator -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/product-on-purpose/pm-skills --path skills/utility-slideshow-creator
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add product-on-purpose/pm-skills --skill utility-slideshow-creator -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/product-on-purpose/pm-skills/tree/HEAD/skills/utility-slideshow-creator/SKILL.md

## When to use it
- generate .pptx presentations from content briefs
- export slides to PDF without manual formatting
- structure decks using 18 standardized layout types
- prepare stakeholder updates and product review decks

## Example prompts
- Create a Q3 update deck from brief.md and export it to pptx
- Generate a JSON deck spec for a product review with alternating dark and light slides
- Build a 5-slide deck covering key milestones and run generate-deck.js

# Slideshow Creator

Generate professional presentations (.pptx and .pdf) from a JSON deck specification. Zero design decisions at generation time - Claude selects slide types and fills content slots; all visual properties are pre-decided by the theme.

## When to Use

- Creating slide decks for stakeholder updates, product reviews, team presentations
- Generating professional .pptx files from content briefs
- Producing consistent presentations without manual formatting
- Exporting presentations to PDF for sharing or archiving

## When NOT to Use

- Creating complex data visualizations (use dedicated charting tools)
- Building interactive web presentations (this produces .pptx, not HTML)
- Editing existing PowerPoint files (this creates new decks from scratch)

## How It Works

**Two-phase architecture:**

1. **Spec phase (Claude)** - Read the content brief, select slide types using decision logic, write a JSON deck specification. Content slots have character limits calibrated to prevent overflow. This is the only phase that costs tokens.
2. **Generation phase (Local script)** - Run `node scripts/generate-deck.js deck-spec.json` to produce .pptx. Optionally run `node scripts/export-pdf.mjs deck-spec.json` for PDF. Deterministic rendering, zero token cost.

Both outputs come from the same JSON spec, so .pptx and .pdf always match.

## 18 Slide Types

| # | Type Key | Purpose | Default Variant |
|---|----------|---------|-----------------|
| 1 | `title_dark` | Opening slide (bold) | dark only |
| 2 | `title_light` | Opening slide (internal/lighter) | light only |
| 3 | `section` | Section divider | dark |
| 4 | `content` | Paragraph explanation | light |
| 5 | `bullets` | 3-6 key points | light |
| 6 | `two_col` | Side-by-side comparison | light |
| 7 | `stat` | Single key metric | light |
| 8 | `dual_stat` | Two metrics compared | dark |
| 9 | `quote` | Testimonial or pull quote | dark |
| 10 | `three_card` | Three parallel concepts | dark |
| 11 | `four_grid` | Four concepts in 2x2 grid | dark |
| 12 | `timeline` | Dates or milestones (max 6) | light |
| 13 | `process_flow` | Sequential workflow (max 5) | light |
| 14 | `agenda` | Meeting agenda (max 7) | light |
```
