# Demo Producer

Universal demo video creation for any content type.

> **Tool versions (2026-Q2):** VHS >= 0.11, Remotion >= 4.0.448. VHS 0.11 added:
>
> - **`Wait` keyword** — supersedes `Sleep N` with a condition-based wait (`Wait "prompt>"` blocks until the given string appears). Use `Wait` over `Sleep` for any prompt that can appear at variable times.
> - **`ScrollUp N` / `ScrollDown N`** — explicit scroll steps inside a recorded session; useful for demonstrating TUI apps and long `less`-style output.
>
> Keep existing `Sleep N` only for fixed visual pacing where no event is available.

## Quick Start

```bash
/ork:demo-producer                    # Interactive mode - asks what to create
/ork:demo-producer skill explore      # Create demo for a skill
/ork:demo-producer plugin ork     # Create demo for a plugin
/ork:demo-producer tutorial "Building a REST API"  # Custom tutorial
/ork:demo-producer --live 4           # Live preview via /ork:dev --live (4-hour public funnel)
```

## --live mode (M127 #1565)

`--live N` is a thin wrapper around `/ork:dev --live N`: it boots the dev stack
behind `portless --funnel` (publicly exposed via Tailscale Funnel), records an
expiry of `N` hours into `.claude/state/live-demos.jsonl`, and prints a public
URL plus `<iframe>` snippet for embedding in customer emails or docs pages.

```bash
/ork:demo-producer --live 4

# Internally runs:
/ork:dev --live 4
# → public URL: https://app.your-tailnet.ts.net
#   iframe: <iframe src="..." />
#   expires: 2026-05-03T20:00Z
```

`/ork:doctor` warns about live demos older than 24 hours so they don't sprawl.
Tear down with `/ork:dev stop`. Tailscale CLI must be installed (only required
behind `--live` — not for static demo recording modes).

## CRITICAL: Task Management is MANDATORY (CC 2.1.16)

**BEFORE doing ANYTHING else, create tasks to track progress:**

```python
# 1. Create main task IMMEDIATELY
TaskCreate(
  subject="Demo Producer: {topic}",
  description="Creating polished demo video for content showcase",
  activeForm="Producing demo for {topic}"
)

# 2. Create subtasks for each production phase
TaskCreate(subject="Content analysis", activeForm="Analyzing content for demo")
TaskCreate(subject="Script & storyboard", activeForm="Generating script and storyboard")
TaskCreate(subject="Record & compose", activeForm="Recording terminal and composing video")
TaskCreate(subject="Final output", activeForm="Rendering final video outputs")

# 3. Set dependencies for sequential phases
TaskUpdate(taskId="3", addBlockedBy=["2"])
TaskUpdate(taskId="4", addBlockedBy=["3"])
TaskUpdate(taskId="5", addBlockedBy=["4"])

# 4. Before starting each task, verify it's unblocked
task = TaskGet(taskId="2")  # Verify blockedBy is empty

# 5. Update status as you progress
TaskUpdate(taskId="2", status="in_progress")  # When starting
TaskUpdate(taskId="2", status="completed")    # When done
```

## Supported Content Types

| Type | Source | Example |

## Interactive Flow

When invoked without arguments, asks 4 questions:

### Question 1: Content Type
```
What type of demo do you want to create?

○ Skill - OrchestKit skill showcase
○ Agent - AI agent demonstration
○ Plugin - Plugin installation/features
○ Tutorial - Custom coding tutorial
○ CLI Tool - Command-line tool demo
○ Code Walkthrough - Explain existing code
```

### Question 2: Format
```
What format(s) do you need?

☑ Horizontal (16:9) - YouTube, Twitter
☑ Vertical (9:16) - TikTok, Reels, Shorts
☐ Square (1:1) - Instagram, LinkedIn
```

### Question 3: Style
```
What style fits your content?

○ Quick Demo (6-10s) - Fast showcase, single feature
○ Standard Demo (15-25s) - Full workflow, multiple steps
○ Tutorial (30-60s) - Detailed explanation, code examples
○ Cinematic (60s+) - Story-driven, high polish
○ Scrapbook (15-35s) - Warm paper, fast cuts, social proof collage (Anthropic style)
```

### Question 4: Audio
```
Audio preferences?

○ Music Only - Subtle ambient background
○ Music + SFX - Background + success sounds
○ Silent - No audio
```

## Pipeline Architecture

> Load details: `Read("${CLAUDE_SKILL_DIR}/references/demo-pipeline.md")` for the full pipeline diagram, generation commands, and output structure.

Content Detector -> Content Analyzer -> Script Generator -> Terminal Script -> VHS Recorder -> Remotion Composer -> Final Outputs (horizontal/vertical/square).

## Template System

Four template architectures for different demo styles. Load `Read("${CLAUDE_SKILL_DIR}/references/template-system.md")` for detailed configuration and the SkillDemoConfig interface.

| Template | Use Case | Duration | Key Feature |
|----------|----------|----------|-------------|
| **TriTerminalRace** | Complexity comparisons | 15-20s | 3-panel split, color-coded difficulty |
| **ProgressiveZoom** | Tutorials, walkthroughs | 20-30s | Zoom transitions, layered reveals |
| **SplitThenMerge** | Before/after, transformations | 15-25s | Split screen -> unified merge |
| **ScrapbookDemo** | Product launches, social proof | 15-35s | Warm paper aesthetic, fast cuts |

Content type templates (skill, agent, plugin, tutorial, cli, code) are mapped in `Read("${CLAUDE_SKILL_DIR}/references/skill-category-mapping.md")`.

## Remotion Composition
