A request crosses a town of autonomous agents. A specialist gets to work, a courier delivers the result, and a hidden link raises a different question: who authorized this coordination, and who benefits?
We have published three English introductions to AgentCollusion on YouTube: a 15-second trailer, a 45-second overview and a two-minute explainer. Each has its own edit, with original 3D block-world animation, English narration and captions in a full-width 16:9 frame.

The full explanation
Twelve chapters explain A2A, the distinction between cooperation and collusion, authority and beneficiaries, and what Scanner checks today.
Watch on YouTubeFrom collaboration to evidence
The story starts with ordinary collaboration. A2A supports discovery, communication and task collaboration; payment settlement and permission to perform a particular action are separate concerns. Similar outputs alone do not establish collusion. The investigation follows messages, memory, tools and actions, asking about authority, objectives and beneficiaries.
Agent Card Scanner is our public-beta tool for inspecting Agent Card declarations and supported signatures. Its findings include evidence and a JSON export. It does not detect collusion at runtime. The town and its future economy are illustrative scenes, not a forecast or a promise of product capabilities.
Built for the wider frame
The films move between a sunset town and a blue-lit investigation lab, with animated characters, moving cameras, task handoffs, hidden message paths and a card-inspection sequence. An original 144 BPM score and sound effects sit beneath synthetic English narration. Captions are embedded in each film.
Claude Opus 5.5 authored the initial story and Blender scene code. Codex reviewed the factual claims and camera framing, corrected animation details, and handled rendering, sound, captions and final edits. The block-world assets are original; no Minecraft assets are used.
