Claude Code v2.1.76 PostCompact Hook + /effort Command + worktree.sparsePaths (Beyond MCP Elicitation)

Releasebot·high signal

Beyond the already-noted MCP Elicitation and Named Sessions, v2.1.76 shipped three additional high-value features: PostCompact hook fires after context compaction, enabling post-compaction state restoration scripts; /effort command provides three-tier (Low/Medium/High) session-level effort control replacing the ad hoc 'ultrathink' keyword; and worktree.sparsePaths enables git sparse-checkout in the --worktree flag, dramatically reducing monorepo clone time by pulling only required directories. The PostCompact hook in particular unlocks persistent memory restore patterns that were previously manual.
