Claude Code CLI v2.1.212 (2026-07-17) makes /fork copy the current conversation into a new background session instead of an in-session subagent (that role moves to /subtask), adds session-wide caps on WebSearch calls and subagent spawns to stop runaway loops, auto-backgrounds MCP tool calls exceeding two minutes, and lets /resume open a picker of past sessions including deleted ones. The release also fixes a plan-mode bug that let file-modifying Bash commands run without a permission prompt.

Why it matters

The rate limits on WebSearch and subagent spawning directly address a known failure mode of agentic loops going out of control, and the plan-mode permission-bypass fix closes a real safety gap for anyone relying on Claude Code's approval gating.

Importance: 2/5

Incremental CLI release addressing agentic safety (rate limits, permission-bypass fix); official GitHub release notes only.
