Claude Code v2.1.161 の更新内容

What's changed

• OTEL_RESOURCE_ATTRIBUTES values are now included as labels on metric datapoints, so you can slice usage metrics by custom dimensions like team or repo

• claude agents rows now show done/total before the detail when work is fanned out; peek shows the longest-running item

• /mcp now collapses claude.ai connectors you've never signed in to behind a "Show unused connectors" row

• Parallel tool calls: a failed Bash command no longer cancels other calls in the same batch — each tool returns its own result independently

• Fullscreen mode: clipboard now uses wl-copy/xclip/xsel on Linux when available, copies to both the clipboard and PRIMARY selection for middle-click paste, and the "hold {key} for native selection" hint now shows the correct key per terminal

• Fixed the /effort dialog, workflow animations, and prompt keyword shimmer not honoring the "Reduce motion" setting

• Fixed forceLoginOrgUUID/forceLoginMethod managed-settings policies blocking third-party provider sessions (Bedrock, Vertex, Foundry, Mantle) alongside the org pin (regression in 2.1.146)

• Fixed background subagent output corrupting claude -p stdout when using --output-format text or json

• Fixed /usage-credits starting a re-login for Team and Enterprise admins instead of pointing to the organization's usage settings page

• Fixed /autofix-pr reporting "cannot run on the default branch" when the session is inside a git worktree or another repository

• Fixed --resume picker not showing sessions from the current directory when it isn't a git worktree (e.g., jj workspaces)

• Fixed Windows hooks that invoke bash explicitly (e.g., /usr/bin/bash script.sh) failing with "command not found" or "cannot execute binary file"

• Fixed OpenTelemetry log events (user_prompt, api_request, tool_result, tool_decision) being silently dropped when emitted before telemetry initialization completed

• Fixed claude mcp list/get/add printing secrets to the terminal: ${VAR} references are no longer expanded, and credential headers and URL secrets are redacted

• Fixed Workflow agents spawned with isolation: "worktree" in background sessions being blocked from editing files inside their own worktree

• Fixed background sessions dispatched from claude agents booting on a stale model from the daemon's environment instead of the model in settings.json

• Fixed a potential crash when rendering Write tool results after resuming a session

• Fixed completed subagents getting stuck showing as running when an error occurs while finalizing their result

• Fixed EADDRINUSE errors from tools that bind Unix sockets under $TMPDIR when CLAUDE_CODE_TMPDIR is set to a deep path

• Improved terminal rendering performance by stabilizing the layout engine's JIT compilation profile

• Improved rendering performance for large file writes

• [VSCode] Added a tip suggesting disabling terminal GPU acceleration (or running /terminal-setup) to fix garbled glyphs
