Claude Code 2.1.146

This release introduces a powerful new /code-review command with optional effort levels, replacing the previous /simplify command for more tailored feedback. Auto mode now offers greater control by no longer suppressing user questions when explicitly requested. Significant reliability improvements include enhanced updater retry logic for transient network failures and faster diff rendering performance for large file edits. Key fixes address Windows PowerShell tool failures, background session re-prompting for permissions, pagination errors in resource lists, and various UI and terminal-specific issues, enhancing overall stability and user experience across platforms.

Improved

  • Improved auto-updater reliability: native version checks and downloads now retry transient network failures instead of failing immediately
  • Improved diff rendering performance for large file edits

Changed

  • Renamed `/simplify` to `/code-review` with an optional effort level (e.g. `/code-review high`)
  • Auto mode no longer suppresses `AskUserQuestion` when the user or a skill explicitly relies on it

Fixed

  • Fixed Windows PowerShell tool failing with "command line is invalid" when `pwsh` is installed via winget or the Microsoft Store (regression in v2.1.124)
  • Fixed MCP `resources/list`, `resources/templates/list`, and `prompts/list` dropping items past page 1 on paginating servers
  • Fixed full-screen strobing in attached background sessions on Windows Terminal while Claude is streaming
  • Fixed the auto-updater status line not showing your current version when an update fails
  • Fixed on Windows, removing a background-job worktree no longer follows NTFS junctions into the main repo
  • Fixed `/background` refusing sessions whose only typed input was a skill or custom slash command
  • Fixed backgrounded sessions re-prompting for tool permissions you already granted with "don't ask again"
  • Fixed `/theme` color editor and "New custom theme" dialogs not responding to Esc
  • Fixed an uncaught exception at the end of streaming sessions when running via the Agent SDK
  • Fixed `forceLoginOrgUUID` and `forceLoginMethod` managed-settings policies not being enforced against third-party-provider and API-key sessions
  • Fixed GNOME Terminal right-click and middle-click paste not inserting text
  • Fixed `CLAUDE_CODE_SUBAGENT_MODEL` not being forwarded to child processes in multi-agent sessions
