    "summary": "Claude Code release changing /fork semantics, adding auto-mode reset and loop limits, backgrounding long MCP calls, and hardening plan mode, hooks, worktrees, and process cleanup.",
    "assimilationNotes": [
      "Latest npm moved from recorded 2.1.209 to 2.1.212.",
      "/fork now copies the conversation into a new background session; the old in-session subagent behavior moved to /subtask, affecting command mapping and agent lifecycle modeling.",
      "New claude auto-mode reset command restores default auto-mode configuration and supports --yes to skip confirmation.",
      "New CLAUDE_CODE_MAX_WEB_SEARCHES_PER_SESSION, CLAUDE_CODE_MAX_SUBAGENTS_PER_SESSION, and CLAUDE_CODE_MCP_AUTO_BACKGROUND_MS environment controls affect runaway-loop and MCP timeout behavior.",
      "Plan mode now blocks file-modifying Bash commands without permission or SDK canUseTool callback, and worktree symlink handling prevents writes outside the repository.",
      "SIGTERM during Bash in print/SDK mode now kills the process tree and exits 143.",
      "Install command remains npm install -g @anthropic-ai/claude-code."
