Claude Code's June 25 Update: /rewind Across /clear, Permanent Agent Stop, ~37% Lower Streaming CPU
Anthropic / Claude Code·medium signal
Claude Code's June 25, 2026 release adds /rewind to resume a conversation from before /clear was run, makes stopping a background agent from the tasks panel permanent (no more agents resurrecting), and auto-reconnects MCP tools when a call returns 401/403. It also cuts CPU use during streaming by about 37% and improves OAuth and sandbox-prompt handling. For daily Claude Code users, the permanent-stop fix and MCP auth auto-recovery remove two long-standing footguns in long agent sessions.
