What it does
Making Demo Videos is an agent skill from nukeop/nuclear. Use when making a demo, tutorial, or feature video of Nuclear. Covers driving the app with WebDriver and real cursor input, recording with OpenScreen, generating voiceover, music, background images, and Nuki mascot images, and composing the video in Remotion (packages/videos).
Its SKILL.md is about 890 tokens, which your agent loads only when the skill is triggered. The skill folder holds 15 other files, including scripts and reference files (for example `references/images.md`, `references/music.md` and `references/openscreen.md`).
It sits in Media & Creative, covering Video production and Text to speech and voice. It works with Remotion and Model Context Protocol. The repository describes itself as: Streaming music player that finds free music for you. The licence is AGPL-3.0.
When your agent uses it
- Feature video of Nuclear
- Tasks that involve Video production
- Tasks that involve Text to speech and voice
Example prompts
- “/making-demo-videos”
Requirements
- Node.js
- A credential in REPLICATE_API_TOKEN
- A credential in OPENROUTER_API_KEY
Workflow steps
8 steps, taken from the first numbered list in SKILL.md.
- Plan the video. Write the steps of the feature, one voice line for each step, and a label for each step. See voice.md.
- Generate the voice lines, the music, and the background image. See voice.md, music.md, and images.md.
- Set up the window and add the WebDriver plugin. See recording.md.
- Write the scenario script. Run it without recording until it runs correctly. See recording.md.
- Record the take with OpenScreen while the scenario runs. See openscreen.md.
- Add zooms, the background, and the frame to the OpenScreen project. Export it. See openscreen.md.
- Compose the video in Remotion and render it. Give the render to the user for review. See remotion.md.
- Remove the WebDriver plugin.
What it can do on your machine
Read from SKILL.md and the folder at commit 27904e9. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 7 files in scripts/ (TypeScript), which the agent can run.
Shell commands in SKILL.md call:
bunpnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
REPLICATE_API_TOKENOPENROUTER_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Making Demo Videos loads about 892 tokens when it runs, and up to ~5.8k if it reads all its reference files. Until then it costs about 74 tokens; SKILL.md has 439 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

- making-demo-videos
- description
- Use when making a demo, tutorial, or feature video of Nuclear. Covers driving the app with WebDriver and real cursor input, recording with OpenScreen, generating voiceover, music, background images, and Nuki mascot images, and composing the video in Remotion (packages/videos).
Making demo videos
A demo video shows one or more features of Nuclear. You drive the app in a demo profile and record it with OpenScreen. Then you add a title card, captions, step labels, a voiceover, and music in Remotion.
Requirements
- macOS with a Retina display.
- Accessibility and Screen Recording permissions for the app that runs you.
- OpenScreen in
/Applications/Openscreen.app. - Bun and ffmpeg.
- A Replicate API token in
REPLICATE_API_TOKENand an OpenRouter API key inOPENROUTER_API_KEY. - BlackHole 2ch as the macOS output device and input device during each take. See openscreen.md.
- Nuclear running with the demo profile. The user starts it with
pnpm dev -- -- -- --profile demoin the repository root.
Procedure
- Plan the video. Write the steps of the feature, one voice line for each step, and a label for each step. See voice.md.
- Generate the voice lines, the music, and the background image. See voice.md, music.md, and images.md.
- Set up the window and add the WebDriver plugin. See recording.md.
- Write the scenario script. Run it without recording until it runs correctly. See recording.md.
- Record the take with OpenScreen while the scenario runs. See openscreen.md.
- Add zooms, the background, and the frame to the OpenScreen project. Export it. See openscreen.md.
- Compose the video in Remotion and render it. Give the render to the user for review. See remotion.md.
- Remove the WebDriver plugin.

Screen control
Before you use the screen, mouse, or keyboard:
- Ask the user for permission. Wait for the answer.
- Run
bun scripts/screen-control.ts start. It shows a notification, plays a sound, and waits 5 seconds.
When you no longer need the screen, run bun scripts/screen-control.ts stop. It shows a notification and plays a different sound.
Keep each period of screen control short. Do generation, export, and render work after stop.
Media review
The user decides about all media quality: voices, music, images, the loudness and clarity of the voiceover, the balance of voice and music, and the final video. Generate samples, variants, and renders into packages/videos/out/, then ask the user to review them. Make the loudness of audio samples the same before the user compares them.
Scripts
| Script | Use |
|---|---|
scripts/screen-control.ts start|stop | Signals the user before and after screen control. |
scripts/webdriver-plugin.ts add|remove | Adds or removes the local WebDriver plugin. |
scripts/webdriver.ts | Finds elements by CSS selector or by text, with screen coordinates. |
scripts/input.ts | Moves the cursor with easing, clicks, scrolls, and types with real macOS events. |
scripts/openscreen.ts | Records a take with OpenScreen and gives the start time. |
scripts/replicate.ts | Runs Replicate models and downloads the output. |
scripts/gemini-tts.ts | Generates voice lines with Gemini TTS on OpenRouter. |
Run the scripts with bun.
