BrainrotShorts is a separate paid service. Motion Graphics starts at their Creator plan. You see the cost before anything is built.

Step 1 Connect it to Claude

In Claude, go to Settings, then Connectors, then Add custom connector. Name it BrainrotShorts and paste this server URL. Click Connect and sign in.

Test it. Ask Claude:
Step 2 Write your script

Copy this prompt into any AI chat and fill in your topic. About 170 words makes a one minute video. Read it out loud once and cut anything you trip on.

View the script prompt
Script prompt Write a one minute explainer script (about 170 words) about [TOPIC] for [WHO IT IS FOR]. Use this shape, in this order: 1. The problem (one or two sentences). Name a pain the viewer already feels. 2. The turn (one sentence). "The fix is not [WHAT THEY TRY]. The fix is [THE REAL FIX]." 3. What it is (one or two sentences). Plain words. No jargon. 4. How it works (three to five short parts). One sentence each. Say how many parts there are first. 5. The one rule (one or two sentences). The single thing that matters most. 6. The next step (one or two sentences). Where to get it and what to do first. Rules: - Short sentences. Write how people talk, not how people write. - Spell out numbers the way you would say them out loud. - Every sentence must be something the screen can show: a file, a number, a step, a result. - No hype words, no questions to the viewer, no "in today's video". - End on the action, not on a slogan. Give me the script as plain text with a blank line between the six parts.
Step 3 Fill in your brand

Copy the brief. Replace every [BRACKET] with your own brand: name, site, colors with hex codes, fonts and mood. Write one line for what each part of your script must show. Put your script at the bottom. Then paste it into Claude.

View the brief
Brand brief Make me an explainer video with BrainrotShorts Motion Graphics. Ground rules: - Show me the cost estimate first. Do not start the build until I say yes. - Read my script below word for word for the voice. Do not rewrite it. - Keep the direction note under 2,000 characters. Settings: - Quality: max - Shape: 9:16 (vertical) - Captions: on - Voice: [VOICE NAME, or show me the voice list and let me pick] My brand: - Name: [BRAND NAME] - Website: [WEBSITE] - Colors: background [COLOR + HEX]; text [COLOR + HEX]; accent [COLOR + HEX], used for numbers and one highlight per frame only - Mood: [THREE WORDS, for example: calm, exact, premium] Direction note (send this as the video's direction): Brand: [BRAND NAME]. Mood: [MOOD]. Headlines in [HEADLINE FONT]. Captions and labels in a clean sans serif, never a serif. Ground: [BACKGROUND COLOR] with a soft texture, never a flat fill. [ACCENT COLOR] only for numbers and one highlight per frame. Frame: do not draw any border, rails or edge ornament. Keep all content and captions at least 90 px inside every edge. Shapes: rounded cards. No divider lines. Show the real subject: the real names, files, numbers and screens the script talks about. Label any mock content as illustrative. Pass and fail colors: [PASS COLOR] for pass, [FAIL COLOR] for fail. Never: explosions, gameplay, cartoon characters, stickers, emoji, confetti, neon, stock people or faces. End card: [BRAND NAME] and [WEBSITE] on [BACKGROUND COLOR]. What each part of the script must show (one line per part): - Part 1 shows: [WHAT] - Part 2 shows: [WHAT] - Part 3 shows: [WHAT] - Part 4 shows: [WHAT] - Part 5 shows: [WHAT] - Part 6 shows: [WHAT] My script: [PASTE YOUR SCRIPT HERE]
Step 4 Approve the cost, then wait

Claude sets up the project, makes the voice and shows you the cost. Nothing is built until you say yes. Max quality takes about 50 to 80 minutes; High takes about 30 to 50. When it's done, ask Claude for the download link.
Step 5 Add your frame (optional)

Lay your own frame over the finished video, like the one in the example. You need ffmpeg and a PNG frame with a see-through center, the same shape as the video. The script is in the kit.

The script behind the example

184 words, 64 seconds. Problem, turn, what it is, how it works, the one rule, the next step.

Read the example script

Example script

Every coding agent has the same problem. Each session starts from amnesia. It forgets what it was doing, drifts off scope, and calls the work done when it simply got tired.

The fix is not a better prompt. The fix is a harness.

A harness is a small set of files inside your project that tells the agent how to start, what done actually means, and where the last session left off.

It has five parts. Instructions, so the agent starts the same way every time. State, so it remembers the work. Verification, a gate that fails when the code is broken. Scope, so nothing stays half finished. And lifecycle, a handoff note so the next session picks up cleanly.

Harness Creator is a skill that builds these for you. Then it audits your project with a one hundred point score and shows you the weakest part.

One rule matters most. The verification gate is the product. If it never fails, the harness is decoration.

Install it with one command on Keys Hub. Point it at a real project. And make your agents accountable.

What we learned

It follows layout, color and frame direction well
It may not use the exact fonts you name; add your own text layer if type matters
Name your pass and fail colors or it picks its own
