Claude-Code v2.1.105 Release: Worktree Improvements, Plugin Monitors, and UI Fixes

New Features and Improvements

Claude-Code v2.1.105 introduces several functional enhancements and quality-of-life improvements for developers using the AI coding assistant.

The EnterWorktree tool now accepts a path parameter to switch into an existing worktree of the current repository, providing more flexibility in repository management workflows.

Plugin developers gain new capabilities with PreCompact hook support: hooks can now block compaction by exiting with code 2 or returning {"decision":"block"}. Background monitor support is added via a top-level monitors manifest key that auto-arms at session start or on skill invoke.

The command /proactive is now an alias for /loop, offering alternative command options for users.

Performance and Reliability Updates

API stream handling is improved: streams now abort after 5 minutes of no data and retry non-streaming instead of hanging indefinitely. Network error messages are enhanced to show a retry message immediately instead of displaying a silent spinner.

The WebFetch tool is improved to strip <style> and <script> contents from fetched pages, preventing CSS-heavy pages from exhausting the content budget before reaching actual text.

Stale agent worktree cleanup now removes worktrees whose PR was squash-merged instead of keeping them indefinitely. MCP large-output truncation prompts are enhanced to give format-specific recipes (e.g., jq for JSON, computed Read chunk sizes for text).

UI and Display Improvements

File write display is optimized: long single-line writes (e.g., minified JSON) are now truncated in the UI instead of paginating across many screens. The /doctor layout is improved with status icons, and users can press f to have Claude fix reported issues.

/config labels and descriptions are updated for clarity. Skill description handling is enhanced with the listing cap raised from 250 to 1,536 characters, and a startup warning is added when descriptions are truncated.

Bug Fixes

This release addresses over 30 issues, including:

• Images attached to queued messages (sent while Claude is working) being dropped
• Screen going blank when the prompt input wraps to a second line in long conversations
• Leading whitespace getting copied when selecting multi-line assistant responses in fullscreen mode
• Leading whitespace being trimmed from assistant messages, breaking ASCII art and indented diagrams
• Garbled bash output when commands print clickable file links (e.g., Python rich/loguru logging)
• Alt+enter not inserting a newline in terminals using ESC-prefix alt encoding, and Ctrl+J not inserting a newline (regression in 2.1.100)
• Duplicate "Creating worktree" text in EnterWorktree/ExitWorktree tool display
• Queued user prompts disappearing from focus mode
• One-shot scheduled tasks re-firing repeatedly when the file watcher missed the post-fire cleanup
• Inbound channel notifications being silently dropped after the first message for Team/Enterprise users
• Marketplace plugins with package.json and lockfile not having dependencies installed automatically after install/update
• Marketplace auto-update leaving the official marketplace in a broken state when a plugin process holds files open during the update
• Stdio MCP server emitting malformed (non-JSON) output hanging the session instead of failing fast with "Connection closed"
• MCP tools missing on the first turn of headless/remote-trigger sessions when MCP servers connect asynchronously
• /model picker on AWS Bedrock in non-US regions persisting invalid us.* model IDs to settings.json when inference profile discovery is still in-flight
• 429 rate-limit errors showing a raw JSON dump instead of a clean message for API-key, Bedrock, and Vertex users
• Crash on resume when session contains malformed text blocks
• /help dropping the tab bar, Shortcuts heading, and footer at short terminal heights
• Malformed keybinding entry values in keybindings.json being silently loaded instead of rejected with a clear error
• CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC in one project's settings permanently disabling usage metrics for all projects on the machine
• Washed-out 16-color palette when using Ghostty, Kitty, Alacritty, WezTerm, foot, rio, or Contour over SSH/mosh
• Bash tool suggesting acceptEdits permission mode when exiting plan mode would downgrade from a higher permission level

This release is for developers using Claude-Code who want improved worktree management, better plugin monitoring capabilities, and numerous bug fixes affecting UI display, terminal compatibility, and MCP server handling.
