[Release] anthropics/claude-code v2.1.157: v2.1.157

Claude Code v2.1.157 introduces automatic plugin loading from `.claude/skills` directories, enhanced agent management with worktree switching, improved telemetry with tool parameters, and numerous bug fixes across terminal UI, image handling, session management, and IDE integrations. Key improvements include plugin scaffolding commands, autocomplete enhancements, better worktree cleanup, and performance optimizations for long conversations.

Key Points

• •Plugins in `.claude/skills` are now auto-loaded without marketplace requirement; use `claude plugin init <name>` to scaffold new plugins
• •Agent field in `settings.json` is honored for dispatched sessions with `--agent <name>` override option
• •`EnterWorktree` can switch between Claude-managed worktrees mid-session for flexible development workflows
• •Tool telemetry now includes `tool_parameters` (bash commands, MCP/skill names) when `OTEL_LOG_TOOL_DETAILS=1` is set
• •Claude-managed worktrees are left unlocked after agent completion, enabling proper cleanup with `git worktree remove/prune`
• •Fixed critical issues: unprocessable images no longer crash requests, sandbox permission prompts removed in auto/bypass modes, background agent worktrees no longer orphaned
• •Session management improvements: idle subagents properly retire, Esc cancels slow operations, resumed sessions show correct date to model
• •Terminal and IDE fixes: copy-on-select works in tmux, `--resume` reports background subagents, fullscreen mode session picker no longer leaves artifacts
• •Performance optimized for long/resumed conversations by eliminating redundant message-rendering recomputations
• •New `/config` setting to disable workflow keyword triggering, preventing accidental workflow activation from the word 'workflow' in prompts
