Claude Code gains Ultracode mode

Ultracode mode combines xhigh reasoning and automatic Dynamic Workflows. Claude automatically breaks down tasks, spawns parallel sub-agents, and uses result verification to ensure accuracy.
Requirements are Opus 4.8 or 4.7, Claude Code 2.1.154+, and Dynamic Workflows enabled via /config. The mode only applies to the current session and must be re-selected via /effort on new launches.
Ultracode suits large-scale tasks like full codebase security audits or refactoring hundreds of thousands of code lines. Token consumption is significantly higher due to parallel agent activity.
