Feature request: Codex-style live steering (inject input into the in-flight turn)

What I'd like

A Codex-style "live steering" capability: the ability to send a message while Claude is mid-turn and have it injected into the current reasoning/tool loop to nudge or redirect — without a hard interrupt and without losing the agent's place.

How it works today

Claude Code already supports:

• Queue while it works — a message typed during a run is delivered at the next step boundary.
• Esc — interrupt the current action, then type a new direction.
• Esc Esc — rewind and edit an earlier message.

These cover redirection well, but a queued message is only picked up at the next step boundary, so it feels less immediate than OpenAI Codex CLI, where input continuously steers the in-flight turn.

Request

Optionally inject queued user input into the current turn as soon as it arrives (between tool calls / mid-stream) so guidance takes effect immediately — matching the Codex steering UX. Ideally a configurable choice between live-steer and the current queue-at-boundary behavior.

Environment

• Claude Code CLI on Windows 11
• Model: Claude Opus 4.x
