Claude Code 2.1.224 Ships Self-Hosted Runners, Cross-Session Agent Messaging, and Kills the 200-Subagent Cap
Anthropic released Claude Code 2.1.224 on Aug 7, adding `claude self-hosted-runner` so Team/Enterprise customers can host web, mobile, and desktop sessions on their own machines or containers, plus cross-session `SendMessage`/`ListAgents` so sessions on any of your machines can message each other (macOS and Linux). It removes the 200-subagent-per-session spawn cap, adds sandbox credential-masking with JWT claim masking and AWS SigV4 re-signing, an `archive` plugin source with SHA-256 pinning, and fixes a sandbox deny bypass where `denyRead: "~/.aws/"` written with a trailing slash was silently ignored on Linux and macOS. For anyone running long multi-agent sessions, the spawn-cap removal and the trailing-slash deny fix are the two lines that change behavior today.
