Claude Code v2.1.224 adds self-hosted runners and cross-session agent messaging
Anthropic
Claude Code 2.1.224 adds `claude self-hosted-runner` for running web/mobile/desktop sessions on your own machines, cross-session SendMessage/ListAgents so sessions can message each other across machines, new sandbox credential-masking options (JWT-aware masking, AWS SigV4 re-signing), and an archive-based plugin install source. It also fixes session-directory collisions on long project paths and silently-failed SendMessage deliveries, following yesterday's v2.1.223 permission-bypass fix.
Why it matters
Self-hosted runners and cross-session messaging extend Claude Code from a single-session CLI toward a distributed multi-agent orchestration tool for teams.
Importance: 2/5
Notable feature update (self-hosted runners, cross-session messaging) plus security hardening, continuing yesterday's patch series.
