`Claude Code` `v2.1.154`: `Opus 4.8`, dynamic workflows, cheaper fast mode

Background workflows can now fan work across tens to hundreds of agents. This is a serious step toward larger autonomous coding runs, with cost and safety controls worth testing now.

[ KEY POINTS ]
  1. Opus 4.8 is now available with high effort by default, plus /effort xhigh for harder tasks. Expect better results on deep refactors and debugging.
  2. Dynamic workflows let Claude create and run multi-agent workflows in the background. Use /workflows to inspect runs instead of manually coordinating subtasks.
  3. Fast mode on Opus 4.8 costs 2x standard rate for 2.5x speed. Good for batch edits where latency beats token efficiency.
  4. /simplify now performs cleanup-only review and applies fixes. It is better suited to reuse, simplification, efficiency, and code altitude, not bug hunting.
  5. Safety and ops got sharper: rm -rf $HOME trailing-slash blocking, pending MCP approval display, and stronger data-exfiltration detection.
