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.
releaseHighlights
- /fork creates a background session; /subtask keeps the in-session subagent behavior.
- claude auto-mode reset with optional --yes.
- Session caps for WebSearch and subagent spawns.
- Automatic backgrounding for long MCP tool calls.
- Plan-mode, worktree, hook, and SIGTERM hardening.
