🤖 Claude Code 更新 v2.1.76

发布日期: 2026-03-17
📋 版本维护

✨ 新增功能

  • Added MCP elicitation support — MCP servers can now request structured input mid-task via an interactive dialog (form fields or browser URL)
  • Added new Elicitation and ElicitationResult hooks to intercept and override responses before they’re sent back
  • Added -n / --name <name> CLI flag to set a display name for the session at startup
  • Added worktree.sparsePaths setting for claude --worktree in large monorepos to check out only the directories you need via git sparse-checkout
  • Added PostCompact hook that fires after compaction completes
  • Added /effort slash command to set model effort level
  • Added session quality survey — enterprise admins can configure the sample rate via the feedbackSurveyRate setting

🐛 重要修复

  • Fixed deferred tools (loaded via ToolSearch) losing their input schemas after conversation compaction, causing array and number parameters to be rejected with type errors
  • Fixed slash commands showing “Unknown skill”
  • Fixed plan mode asking for re-approval after the plan was already accepted
  • Fixed voice mode swallowing keypresses while a permission dialog or plan editor was open
  • Fixed /voice not working on Windows when installed via npm
  • Fixed spurious “Context limit reached” when invoking a skill with model: frontmatter on a 1M-context session
  • Fixed “adaptive thinking is not supported on this model” error when using non-standard model strings
  • Fixed Bash(cmd:*) permission rules not matching when a quoted argument contains #
  • Fixed “don’t ask again” in the Bash permission dialog showing the full raw command for pipes and compound commands
  • Fixed auto-compaction retrying indefinitely after consecutive failures — a circuit breaker now stops after 3 attempts

⚡ 优化改进

  • Improved --worktree startup performance by reading git refs directly and skipping redundant git fetch when the remote branch is already available locally
  • Improved background agent behavior — killing a background agent now preserves its partial results in the conversation context
  • Improved model fallback notifications — now always visible instead of hidden behind verbose mode, with human-friendly model names
  • Improved blockquote readability on dark terminal themes — text is now italic with a left bar instead of dim
  • Improved stale worktree cleanup — worktrees left behind after an interrupted parallel run are now automatically cleaned up
  • Improved Remote Control session titles — now derived from your first prompt instead of showing “Interactive session”
  • Improved /voice to show your dictation language on enable and warn when your language setting isn’t supported for voice input
  • Updated --plugin-dir to only accept one path to support subcommands — use repeated --plugin-dir for multiple directories
  • [VSCode] Fixed gitignore patterns containing commas silently excluding entire filetypes from the @-mention file picker

💡 深度点评

核心亮点

  • MCP Elicitation 支持：MCP server 现在可以在任务执行过程中通过交互式对话（如表单字段或浏览器 URL）请求结构化输入，增强了复杂任务中的人机协作能力。
  • Monorepo 性能优化：引入 worktree.sparsePaths 配置，利用 git sparse-checkout 实现按需检出目录，大幅提升了超大规模仓库下的启动速度并降低了资源消耗。
  • 任务控制增强：新增 /effort 命令支持手动调节模型的推理力度，配合 -n 启动标志自定义会话显示名称，进一步细化了开发者的操作权限。

值得注意的修复

  • 工具调用稳定性：修复了延迟加载工具（ToolSearch）在会话压缩后丢失 Input Schema，导致数组和数字参数报类型错误的回归缺陷。
  • 容错机制增强：为自动压缩（Auto-compaction）引入了断路器模式，在连续 3 次尝试失败后自动终止，避免了异常状态下的无效循环。

个人评价

v2.1.76 版本是一个侧重于“工程健壮性”的迭代。它不仅解决了大规模代码库下的性能瓶颈，还通过完善 MCP 协议和会话压缩逻辑，显著提升了长时会话的可靠性。这些针对底层架构和边缘场景的打磨，标志着 Claude Code 正在从简单的 AI 助手演进为更专业、可预测的生产力工具。
