🛠️ teardown Turns Claude Into a 3D Simulator

⭐ 2,640 · elvarofficial/teardownRepo

A repo dropped this weekend with a Claude Code skill I didn't expect: ask how a hydraulic excavator arm works, and it builds you a working 3D simulator you can spin around and take apart. Asking AI to show you how something works used to get you a paragraph. This gets you a machine you can open.

A Claude Code skill that turns any machine into a 3D simulator you can take apart.

You ask an AI "how does a V8 engine work" and get a wall of text you forget in ten minutes. This builds the thing instead: one offline HTML page where the machine runs, every panel shows the real numbers, and you click any part to see it doing the work.

Quick start: npx skills add elvarofficial/teardown -g -a claude-code, then npm install && npx playwright install chromium once in the installed folder.

Catch: you need Node.js 20+, and video export needs ffmpeg plus Python 3 for sound.

rea-videoRepo ⭐ 4,316

Point it at any video and it tells you, shot by shot, what's real footage and what's AI. Catch: you need ffmpeg and Python 3.10+, and it's built to be driven by an agent (Claude Code or Codex), not run cold.

cactusRepo ⭐ 14,590

Sub-50mb runtime that runs text, speech, and vision models locally on a consumer device. Catch: pip install -U cactus-compute needs Python 3.9+, and the engine downloads and caches model weights on first run.

floorplanTool ⭐ 3,234

Ask Claude to map your own app and get a diagram nobody ever drew for you. Catch: it maps code, so it's for anyone building software, and it runs inside Claude Code or Codex.

Turn a hard no into a reply that doesn't leave the door half open

Start Here is one prompt from our pack, every issue, tested on ChatGPT and Claude. If you've ever stared at a customer message you have to say no to and typed four different apologies before deleting all of them, this one's for you. Tap Copy prompt, paste it into the AI app you already use, and fill in what they asked for, your real reason, and what you can still offer them.

Copy prompt

The line that makes it work: "Give the answer in the first two sentences. Do not warm them up for four lines and then say no." Most people bury the no under three sentences of cushioning, and the customer reads all three waiting for the "but." Leading with the decision reads as respectful, not cold.

TRY THIS: open your email or your messages right now, find the one unanswered request you've been avoiding because the answer is no, and run it through this before you close the tab.

This is one of 250 in the AIgent prompt pack. The rest, plus guided builds with Mike on video, are inside the AIgent membership: Join the AIgent membership.

Frontier Signals

Anthropic signed a $3.4 billion deal to generate gas-fired power for its data centers. When a model company starts making its own electricity, that's a tell about how much compute the next generation needs, and that cost eventually shows up in API pricing. (Financial Times)

A Claude Code user says the tool sent their email address to third-party sites in its User-Agent header during web searches. They report dozens of scam emails a day since, and the issue is filed as a security bug. If you run Claude Code against sites you don't control, check what that header carries. (GitHub)

Chainalysis says hackers using AI agent-assisted techniques stole names, password hashes and live tokens for every user on its platform. Its customers include the FBI, the US Air Force, Microsoft and Barclays. Agent-assisted attacks are already showing up in real breaches. (Ars Technica)

Apple wants Siri to work like an agent. Bloomberg's Mark Gurman reports Apple is pushing Siri toward ongoing, multi-step tasks, possibly as early as next year. If that ships at OS scale, "agent" stops being a builder's word and becomes a button on a billion phones. (The Verge)
