Tip: Use /config key=value to Flip Any Claude Code Setting Without Leaving the Prompt
Claude Code Docs·medium signal
The new `/config key=value` syntax lets you toggle any setting mid-session — e.g. `/config thinking=false` to disable extended thinking for a quick task, then flip it back. Because it works in `-p` and Remote Control, you can script per-invocation overrides instead of maintaining separate settings files. Pairs well with the new `CLAUDE_CLIENT_PRESENCE_FILE` marker to silence phone alerts while you're actively driving the terminal.
