Fix2.1.203

Claude Code 2.1.203

This release adds login expiration warnings, improves background session stability and performance, fixes multiple crashes and stalling issues on macOS and Windows, and enhances the agent interface with better visibility and error messages.

  • Added a warning when your login is about to expire, so you can re-authenticate before background sessions are interrupted
  • Added a grey ⏸ badge to the footer when in manual permission mode, making the active mode always visible
  • Added the session's additional working directories to MCP roots/list, with notifications/roots/list_changed sent when the set changes
  • Fixed opening or switching background agent sessions on macOS stalling for 15–20 seconds due to a false low-memory detection (regression in 2.1.196)
  • Fixed background sessions becoming permanently unresponsive to attach, replies, and stop when the daemon's session token went stale — the session now recovers automatically
  • Fixed returning to claude agents silently stopping running subagents and re-running the prompt from scratch — their work now carries over
  • Fixed a memory and per-turn CPU regression in interactive sessions: the context-usage indicator no longer re-analyzes the entire transcript after every turn
  • Fixed background agents inheriting a stale PATH from the daemon instead of the dispatching shell, causing missing tools on Windows
  • Fixed background and agent-view sessions dropping a shell-exported ANTHROPIC_BASE_URL, which sent API keys to the default endpoint and failed with 401
  • Fixed Bash failing with "argument list too long" in repos with many git worktrees
  • Fixed worktree-isolated subagents sometimes running shell commands in the parent checkout instead of their own worktree
  • Fixed worktree creation rejecting nested repositories in multi-repo workspaces, leaving background sessions unable to isolate and edit
  • Fixed background agents crash-looping when their working directory was deleted, replaced by a file, or became an invalid path — they now fail once with a clear error
  • Fixed a background daemon auto-upgrade failure silently killing all running background sessions
  • Fixed TaskStop and TaskOutput failing to find background agents spawned by another agent — errors now list running agents by id and description
  • Fixed the claude agents composer discarding your typed message when a slash command isn't available there
  • Fixed the agent list crashing when opening a stopped session whose conversation was already open in another session
  • Fixed background sessions showing "Needs input" in the agent list after the question was already answered
  • Fixed background agent startup failures showing only "exit_with_message" instead of the actual error
  • Fixed background sessions ignoring effortLevel changes in settings.json when forked through the daemon
  • Fixed attached background sessions ignoring CLAUDE_CODE_DISABLE_MOUSE and CLAUDE_CODE_DISABLE_MOUSE_CLICKS opt-outs
  • Fixed /exit incorrectly warning about running background agents after all named agents had completed
  • Fixed background sessions started from a non-git directory unable to edit files when a WorktreeCreate hook was configured
  • Fixed the @ directory picker in claude agents not showing registered git worktrees
  • Fixed background task output on Windows being permanently replaced by an empty file after /clear
  • Fixed content jumping when scrolling up through long transcript history
  • Fixed the terminal flickering and jumping while typing in bash mode when a shell-history suggestion was shown
  • Fixed literal ^[[I / ^[[O escape codes being printed when reattaching to a background session
  • Fixed LSP-only plugins being incorrectly flagged for disuse when their language servers deliver diagnostics or answer navigation requests
  • Improved responsiveness while long responses stream: live-preview updates no longer re-render the whole screen
  • Improved subagent behavior: agents are now less likely to re-delegate their entire task to another subagent
  • Reduced binary size by ~7 MB and startup memory by ~7 MB by loading a large bundled dependency lazily instead of inlining it
  • Changed left arrow to no longer close the background tasks, diff, and workflow detail views — press Esc instead
  • Changed the empty claude agents view to always show the organized sections (Needs input / Working / Completed) with descriptions
  • Removed the startup "claude command missing or broken" warnings — they now appear in /doctor and /status instead
  • Removed a redundant navigation hint from the claude agents footer
  • [VSCode] Added a Settings toggle for "Enable Remote Control for all sessions"
