Claude Code v2.1.146: /code-review Command, Pagination Fix, Windows PowerShell Fix

Claude Code v2.1.146 is out with a handful of practical fixes and one notable rename: /simplify is now /code-review with an optional effort level parameter (e.g., /code-review high). The release also addresses several Windows-specific bugs and improves pagination handling for MCP servers.

Key Changes

• Renamed command: /simplify → /code-review. Now accepts an optional effort level like high to control depth of analysis.
• Auto mode fix: No longer suppresses AskUserQuestion when the user or a skill explicitly relies on it.
• Windows PowerShell fix: Resolved a regression from v2.1.124 where the tool failed with "command line is invalid" when pwsh is installed via winget or the Microsoft Store.
• MCP pagination fix: Calls to resources/list, resources/templates/list, and prompts/list now correctly return items past page 1 on paginating servers.
• Windows Terminal strobing fix: Full-screen strobing in attached background sessions while Claude is streaming is fixed.
• Auto-updater reliability: Native version checks and downloads now retry transient network failures instead of failing immediately.
• Diff rendering performance: Improved for large file edits.
• Various session and tool fixes: /background no longer refuses sessions with only typed input of a skill or custom slash command; backgrounded sessions no longer re-prompt for tool permissions already granted with "don't ask again"; /theme color editor and "New custom theme" dialogs now respond to Esc.
• Agent SDK fix: Fixed an uncaught exception at the end of streaming sessions when running via the Agent SDK.
• Managed settings enforcement: forceLoginOrgUUID and forceLoginMethod policies now enforced against third-party-provider and API-key sessions.
• GNOME Terminal paste fix: Right-click and middle-click paste now inserts text.
• Subagent model forwarding: CLAUDE_CODE_SUBAGENT_MODEL is now forwarded to child processes in multi-agent sessions.

For developers relying on MCP servers with paginated responses, the pagination fix alone is worth the upgrade. The /code-review rename aligns with the broader trend in AI coding tools toward explicit review commands with configurable depth.
