Claude Code CLI 2.1.205 changelog: New feature: • Added an auto mode rule that blocks tampering with session transcript files 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 · 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 • 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 Other changes: • 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 • /doctor is now a full setup checkup that can diagnose and fix issues; /checkup is its alias • 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 Source: #21205" target="_blank" rel="nofollow noopener">github.com/anthropics/cla…

@ClaudeCodeLog prompt token 增加 11.5% 意味着每次对话成本在上升，但 tools 占比微降，说明工具调用优化了。18 小时一更的频率比多数 LLM 项目快，建议关注 bundle 持续膨胀对速度的影响。
