Claude Code Ships Agent Fleet Management: New --add-dir, --settings, --mcp-config Flags for Background Agent Sessions

Releasebot·medium signal

Claude Code's latest May update adds new `claude agents` CLI flags for configuring dispatched background sessions: --add-dir, --settings, --mcp-config, --plugin-dir, --permission-mode, --model, --effort, and --dangerously-skip-permissions. Fast mode now uses Opus 4.7 by default. The update lands alongside Code with Claude London (May 19-20), where Anthropic showed managed agents with multiagent orchestration, outcomes-based success criteria, and 'dreaming' for cross-session memory recall.
