Claude Code v2.1.152 Release Notes
Claude Code v2.1.152 introduces enhanced code review automation with fix application, improved skills management, and better session handling for power users.
The latest Claude Code release brings significant enhancements to automated code review workflows, skills management, and overall user experience. This update focuses on streamlining development processes and providing more granular control over your coding environment.
What’s New
Enhanced Code Review Automation
The /code-review --fix command now goes beyond analysis to automatically apply review findings directly to your working tree. This powerful feature surfaces reuse opportunities, simplification suggestions, and efficiency improvements while making the changes for you. The /simplify command has been updated to invoke /code-review --fix, making code optimization even more accessible.
Advanced Skills Management
Skills and slash commands can now specify disallowed-tools in their frontmatter, giving you precise control over which tools are available during skill execution. The new /reload-skills command lets you refresh skill directories without restarting your session, and SessionStart hooks can now trigger skill reloading and set custom session titles.
