Summary
A changelog breakdown of Claude Code 2.1.1, an unusually large release with 100+ changes across three areas: the CLI (109 changes), feature flags, and prompt behavior (10 changes). Highlights include skill hot-reload, sub-agents running skills/commands, configurable response language, broad terminal Shift+Enter support, image paste, security fixes for leaked secrets, finer-grained permissions, a new /plan command, and Ctrl+B task backgrounding.
這是 Claude Code 2.1.1 的更新日誌解析，這次發布異常龐大，跨三個領域共 100+ 項改動：CLI（109 項）、功能標誌與提示行為（10 項）。重點包括技能熱重載、子代理可運行技能/命令、可設定回覆語言、主流終端普遍支援 Shift+Enter、圖片貼上、修復敏感資訊洩漏、更細粒度的權限、新增 /plan 命令，以及 Ctrl+B 任務後台化。
Key Points
- CLI: skills hot-reload from ~/.claude/skills without restart; sub-agents can run skills/commands in isolated context.
- Configurable language (e.g. language: “japanese”); Shift+Enter now works in iTerm2, WezTerm, Kitty; slash auto-complete; image paste via Ctrl+V.
- Security: fixed API key/OAuth token leakage in debug logs; CLAUDE_CODE_HIDE_ACCOUNT_INFO env var for screen recording; .gitignore-aware file picking.
- Tasks: new /plan command, Ctrl+B to background all running tasks, output-to-file management.
- Prompt changes: no longer forces official docs for “how to use Claude” questions; drops colon-before-tool quirk (“Let me read the file.” not ”:”); AskUserQuestion limited to clarification, ExitPlanMode handles approval; commit messages drop the ”🤖 Generated with Claude Code” line but keep Co-Authored-By; LSP tools removed in favor of search/read.
- Upgrade via
claude upgrade.
Insights
The prompt-behavior changes reveal product priorities: reducing awkward conversational artifacts (the colon-before-tool issue), tightening the plan-mode interaction model, and loosening the requirement to defer to official docs so the model answers from its own knowledge. Removing LSP tools in favor of generic search/read suggests a deliberate simplification for compatibility over specialized tooling.

Raw Excerpt
句子后不加冒号 … 以前 Claude 会说 “Let me read the file:” 然后执行工具，但这时工具可能不显示，导致冒号很突兀。现在改成 “Let me read the file.” 更自然。
