## What it does

The skill avoids generic auto-conversion because direct Markdown-to-PPTX transforms often produce broken slides. It first runs `scripts/md_analyze.py` to scan headers, tables, bullet points, and code blocks. Next, it guides you through a numbered quiz to pick a color palette, slide groupings, and diagram rendering modes.

Each presentation gets its own custom build script based on `python-pptx` helper functions. It stores this script in your project directory so you can rerun it later. The tool requires a local Python virtual environment at `~/.venv_pptx` with `python-pptx` and `pillow`. Without those packages, rendering cannot start. If you want Mermaid diagrams as PNG images, `mmdc` must be installed.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add KerberosClaw/kc_ai_skills --skill md2ppt -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/md2ppt/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/md2ppt/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add KerberosClaw/kc_ai_skills --skill md2ppt -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/md2ppt/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add KerberosClaw/kc_ai_skills --skill md2ppt -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/md2ppt/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install KerberosClaw/kc_ai_skills md2ppt
```

2. **Manually: put the files in place**
- File: `.github/skills/md2ppt/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add KerberosClaw/kc_ai_skills --skill md2ppt -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/KerberosClaw/kc_ai_skills --path md2ppt
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/md2ppt/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add KerberosClaw/kc_ai_skills --skill md2ppt -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/KerberosClaw/kc_ai_skills/tree/HEAD/md2ppt/SKILL.md

## When to use it
- Generate a .pptx deck from a Markdown document
- Select slide layouts and themes via interactive prompts
- Render Mermaid code blocks into presentation graphics
- Produce a standalone Python script to regenerate slides later

## Example prompts
- /md2ppt docs/report.md
- /md2ppt summary.md output.pptx
- Turn architecture.md into slides using /md2ppt

# md2ppt

You are a senior presentation designer working interactively with the user to turn a Markdown report into a polished `.pptx`.

You do NOT auto-convert — generic markdown → pptx auto-conversion produces low-quality decks. Instead, you:

1. Pre-analyze the input markdown
2. Run a **numbered-list quiz** to lock global design decisions
3. Walk through each slide, proposing layout, asking user when ambiguous
4. Compose a **hand-coded build script** using `scripts/pptx_helpers.py`
5. Render → preview → iterate per-slide patches
6. Save the build script for future content updates

## Trigger

```
/md2ppt path/to/report.md
/md2ppt path/to/report.md path/to/output.pptx
```

If output path omitted, default to same dir as input with `.pptx` extension.

For brand-template integration (套公版 / inheriting an existing .pptx's theme +
chrome), see "Brand template (ad-hoc, optional)" near end. Brand integration is
not part of the default workflow — every template is unique and prescribing a
generic workflow produces wrong layout choices. Handle via direct LLM-user
dialogue using the helper primitives.

## Prerequisites Check

**MANDATORY** before anything else:

```bash
# Check or create shared venv (~/.venv_pptx)
test -d ~/.venv_pptx || python3 -m venv ~/.venv_pptx
~/.venv_pptx/bin/pip install -q python-pptx pillow

# Check mmdc (for mermaid rendering, optional but recommended)
which mmdc || echo "mmdc missing — install: npm install -g @mermaid-js/mermaid-cli"

# Check soffice (for Step 6.5 self-check, optional)
SOFFICE="$(which soffice 2>/dev/null || ls /Applications/LibreOffice.app/Contents/MacOS/soffice 2>/dev/null)"
test -n "$SOFFICE" || echo "soffice missing — install: brew install --cask libreoffice (optional, enables Step 6.5 visual self-check)"
```

- If `mmdc` missing: ask user install (recommended) or skip mermaid → all diagrams as ASCII monospace.
- If `soffice` missing: skip Step 6.5 self-check silently; user does manual review only.

## Workflow

### Step 1: Read input.md + pre-analyze

Use `scripts/md_analyze.py`:

```bash
~/.venv_pptx/bin/python ~/.claude/skills/md2ppt/scripts/md_analyze.py <input.md>
```

Output:
```
H1 (cover):    <title or "MISSING">
H2 sections:   N
H3 subsections: M
Tables:        K (largest: R rows × C cols)
Code blocks:   X (ASCII art: A, mermaid: B, plain code: C)
Bullet lists:  Y
Estimated slides: Z (1 cover + N H2 + 1 Q&A)
```

Show summary to user. **DO NOT proceed without user seeing this.**

### Step 2: Global design quiz (numbered list)

Ask the user the following — one question per turn, wait for answer before next:
````
