“Anthropic deploys three agentic products—claude.ai, Claude Code, and Claude Cowork—using two containment strategies: human-in-the-loop approvals (users approved roughly 93% of permission prompts) and environmental containment (sandboxes, VMs, filesystem and egress controls); Claude Code’s auto mode automates safer approvals and catches roughly 83% of overeager behaviors before they execute.”

#2 📝 Anthropic Engineering How we contain Claude across products - Anthropic deploys three agentic products—claude.ai, Claude Code, and Claude Cowork—using two containment strategies: human-in-the-loop approvals (users approved roughly 93% of permission prompts) and environmental containment (sandboxes, VMs, filesystem and egress controls); Claude Code’s auto mode automates safer approvals and catches roughly 83% of overeager behaviors before they execute. Anthropic withheld Claude Mythos Preview in April 2026 for having too high a blast radius and reports that model-layer defenses are strong but imperfect—Claude Opus 4.7 holds prompt-injection attack success to about 0.1% on single attempts and roughly 5–6% after 100 adaptive attempts—so overlapping defenses across environment, model, and external content are required.
