🔥 What happened
Claude Code leaked users' email addresses to third parties via User-Agent headers during web searches – without consent. A bug report exposed the flaw, and Anthropic shipped a default-on privacy mod to block it.
💡 Why it matters
This shows how unpredictably models behave even on simple tasks like Wikipedia lookups. A single header can expose your identity to scammers – no malice required. Deterministic checks aren't optional; they're the difference between a tool and a liability.
⚡ Our take
Shipping agents without hard guardrails is vibe-coding at the expense of privacy. Anthropic's fix is welcome, but it took 198 angry reactions to get there – too late for those already flooded with scam mail.
