v2.1.205
Claude CodeSummary
This release introduces new security measures in auto mode, including blocking tampering with session transcripts and adding context checks before running destructive commands. Several critical bugs were fixed across agent management, CLI operations, and Windows stability. Additionally, the agent view has been significantly improved to show clearer status headlines and better PR linking.
New Features
- Added an auto mode rule that blocks tampering with session transcript files
- Introduced /doctor as a full setup checkup tool that can diagnose and fix issues; /checkup is now its alias
Bug Fixes
- Fixed --json-schema silently producing unstructured output when the schema was invalid, and schemas using the format keyword being rejected
- Fixed a message sent while Claude was working being silently lost when the turn ended at the --max-turns limit
- Fixed Windows worktree removal deleting files outside the worktree when an NTFS junction or directory symlink existed inside it
- Fixed background agents staying shown as "failed" or "completed" in the agent list after being resumed with SendMessage
- Fixed background jobs flipping from "needs input" back to "working" in the agent list when the agent's turn contained no readable text
- Fixed claude attach erroring when a background agent was mid-upgrade restart instead of waiting for it to come back
- Fixed session-to-PR linking missing a PR created in a Bash call whose output exceeded the 30K inline limit
- Fixed claude mcp add-from-claude-desktop getting stuck when a server name contains unsupported characters; invalid names are now reported and remaining servers still import
- Fixed a plugin LSP server that fails to initialize preventing a valid LSP server from another plugin handling the same file extension
- Fixed a Windows crash when the directory Claude was launched from is deleted, locked, or unmounted while a command is running
- Fixed a crash when a file watcher was closed while a directory scan was still in flight
- Fixed project verify skills being rewritten on every session instead of only when a documented command changed
- Fixed the agent view rendering one line too high and clipping its header when the job list slightly overflowed the screen
- Fixed background tasks in the web and mobile Remote Control panels showing stale "Running" status by forwarding full task state on every membership change
- Fixed Cowork VM-mode local-agent sessions failing to start with "Not logged in 342200224 Please run /login" on CLI 2.1.203+
Improvements
- Improved auto mode to ask before running rm -rf on a variable it can't resolve from context
- Auto-update binary downloads now stream to disk instead of buffering in memory, cutting the updater's peak memory usage by roughly 400 MB
- Background task notifications now explicitly state that no human input has occurred, preventing fabricated in-transcript approvals from being acted on
- Improved agent view: sessions that edit, merge, comment on, or push to an existing PR now link it in claude agents
- Improved agent view: rows now show a colored state word and a classifier-written headline instead of raw tool call text, and the peek opens with full status including the exact ask for blocked sessions
- Reserved the "Claude Browser" MCP server name (alongside "Claude Preview") ahead of the Claude Desktop pane rename; user-configured MCP servers can no longer register under either name
