Anthropic · Claude Managed Agents Platform + 2026 Product/Security Updates (Official Blog Condensed)
Themed condensation of 13 official 2026 blog posts. The core is Claude Managed Agents — a set of APIs for "renting Anthropic's cloud infrastructure to run long-horizon agents": memory (cross-session memory) + dreaming (sleep-time self-improvement) + outcomes (scored self-correction) + multiagent (lead-worker collaboration) + self-hosted sandboxes (bring-your-own sandbox) + MCP tunnels (private network tunnels), underpinned by a decoupled meta-harness design of three components: "brain (Claude + harness) / hands (sandbox) / session logs". Additional content covers the Claude Code desktop app rebuild (parallel agents) + harness design philosophy (use tools Claude already knows / keep asking "what can I turn off") + enterprise deployment data + containment security architecture for three products + a security checklist for AI-accelerated offense and defense + chart visualization / frontend Skills / lifestyle connectors.
