Claude Code shipped versions 2.1.149 through 2.1.152 over the past few days — with a handful of features that noticeably improve the daily workflow, and a security fix that Windows users should install immediately.
/code-review —fix: Reviews that actually repair
The headline feature: /code-review --fix applies code review findings directly to your working tree. Instead of just showing a list of issues, Claude Code now fixes repetitions, unnecessary complexity, and efficiency problems on the spot. /simplify now calls /code-review --fix internally — the old command still works.
Hot-reload skills without restarting
New features for skill developers: /reload-skills re-scans skill directories without restarting the session. Even better — SessionStart hooks can now return reloadSkills: true, making skills installed by the hook immediately available in the same session.
Also, skills and slash commands can now set disallowed-tools in frontmatter to remove specific tools from the model while the skill is active. Useful when a skill shouldn’t have shell access, for example.
PowerShell security fix (Windows users, take note)
The most important fix in v2.1.149: a permission bypass in PowerShell has been closed. Built-in PowerShell functions like cd.., cd\, cd~, and X: could change the working directory without triggering Claude Code’s permission system. This could theoretically allow access to files outside the workspace.
Windows users should update immediately: claude update or winget upgrade Anthropic.ClaudeCode.
More changes
A new MessageDisplay hook lets hooks transform or hide assistant message text as it’s displayed. Admins get pluginSuggestionMarketplaces to allowlist org-specific marketplaces for plugin suggestions. And in Vim mode, / now opens a reverse history search — matching bash/zsh vi-mode behavior.
My take
Not a spectacular release, but a useful one. The /code-review --fix command alone probably saves me half an hour a day. And skill hot-reloading makes developing custom skills much more pleasant. Good, solid work.
