Claude Code v2.1.157 の変更点

What's changed

• Plugins in .claude/skills directories are now automatically loaded, no marketplace required

• Added claude plugin init to scaffold a new plugin in .claude/skills

• Added autocomplete for /plugin arguments: subcommands, installed plugin names, and plugins from known marketplaces

• claude agents: the agent field in settings.json is now honored for dispatched sessions, with --agent to override it

• EnterWorktree can now switch between Claude-managed worktrees mid-session

• tool_decision telemetry events now include tool_parameters (bash commands, MCP/skill names) when OTEL_LOG_TOOL_DETAILS=1

• Worktrees managed by Claude are now left unlocked when the agent finishes, so git worktree remove/prune can clean them up

• Fixed unprocessable images (zero-byte, corrupt) attached via paste, MCP, or dialog crashing the request instead of becoming a text placeholder

• Fixed sandbox network permission prompts appearing in auto and bypass-permissions mode when using the desktop app, IDE extensions, or SDK

• Fixed claude agents completed sessions not retiring when an idle subagent was still parked or had leaked a backgrounded shell

• Fixed claude agents pressing Esc not cancelling a slow "opening…", leaving the list unresponsive

• Fixed background agent worktrees under .claude/worktrees/ being orphaned after the 30-day job retention sweep

• Fixed background sessions re-attached after a sleep/wake not telling the model the correct date

• Fixed copy-on-select in claude agents not reaching the system clipboard inside tmux with set-clipboard on (regression in 2.1.153)

• Fixed --resume not reporting background subagents that were running when the previous Claude Code process exited

• Fixed the --resume session picker leaving its contents on the terminal after exiting in fullscreen mode

• Fixed --worktree and --worktree --tmux returning to the canonical repo root instead of the current linked worktree

• Fixed the /model picker showing an incorrect "Newer version available" hint when the selected model is already the newest in its family; the pinned-model row now shows the model's description instead of its raw ID

• Fixed literal markdown markers (backticks, asterisks) appearing in the in-progress message text in fullscreen mode

• Fixed the terminal freezing after approving the managed-settings security dialog at startup

• Fixed a rare duplicate line appearing in scrollback after the terminal UI redraws

• Fixed right-click paste duplicating the clipboard in the VS Code, Cursor, and Windsurf integrated terminals

• WSL: fixed image paste (alt+v keybinding), screenshot paste on Windows 11, and added support for dragging images from Windows Explorer

• Improved performance of long and resumed conversations by eliminating redundant message-rendering recomputations

• /terminal-setup now disables GPU acceleration in VS Code/Cursor/Windsurf integrated terminals to prevent garbled-text rendering

• The Feature of the Week credit-claim status now appears as a notification in the status area instead of a line above the prompt

• claude agents: slash-command autocomplete in the dispatch input now matches substrings

• Removed the "bash commands will be sandboxed" startup banner — sandbox status still shows in /status and when a command is blocked

• Removed the "/ide for …" startup hint toast

• [IDE] Fixed clicking Stop while a background subagent is running not actually stopping it

• [VSCode] Fixed the fast mode indicator not appearing on Opus 4.8

• Pressing backspace right after a workflow trigger keyword now dismisses the workflow request (same as alt+w) instead of deleting a character

• Added a "Workflow keyword trigger" setting in /config to stop the word "workflow" in a prompt from triggering a dynamic workflow
