Claude Code 2.1.76 adds MCP elicitation, sparse worktrees

MCP elicitation is the standout: it lets the agent pause mid-task and ask for what it needs, shifting Claude Code from passive executor to active collaborator.

• –MCP servers can trigger form-field or browser-URL input dialogs during task execution, enabling richer human-in-the-loop workflows without breaking the agentic loop
• –`worktree.sparsePaths` makes `--worktree` practical for large monorepos — only the directories you need get checked out via git sparse-checkout
• –The auto-compaction circuit breaker (3-strike stop) kills a long-standing silent-hang footgun that frustrated power users
• –Remote Control gets meaningful hardening: session survival across idle reaps, message batching instead of one-at-a-time queuing, and WebSocket disconnect recovery
• –New `PostCompact`, `Elicitation`, and `ElicitationResult` hooks give enterprise admins and plugin authors fine-grained control over the agent lifecycle
