  • AGENTS FOUND 266 CVEs TOGETHER, 21 ALONE. Anthropic put 45 agents in a sandbox with a shared forum. They self-organized into a tournament, found 12x more vulnerabilities than isolated agents, and showed what mob mentality looks like when the mob is AI.
  • ANTHROPIC IS EDITING YOUR WORDS. Every Claude output now carries a probabilistic fingerprint to satisfy EU AI law. The original support doc said it doesn't change meaning or quality. John Gruber tested it. That was false.
  • Tool of the Week: DeepSeek Harness. MIT-licensed agent runtime where model adapter, tool registry, session log, and agent loop are all swappable plugins. 33K stars in hours. Amazon Bedrock is in the provider catalog โ€” configure it with your existing AWS credentials. Not production-ready, and still worth understanding now.

Anthropic Let 45 Agents Loose. They Started a Tournament.

The experiment sounds simple. Give 45 agents a shared sandbox, a forum to communicate, and 15 open-source codebases to audit. See what happens.

What happened: 266 CVEs. The isolated parallel agents running the same task found 21.
