…hind it For Claude, Steer was indistinguishable from Queue. The message reached the CLI's stdin at once, but Claude only folds a queued user message into a running turn between tool rounds, so behind a long tool call or a subagent it sat there arbitrarily long and the send-now arrow appeared to do nothing. The only affordance that did land was Stop, which for Claude closes the session and takes its commands and subagents with it. ProviderSendTurnInput gains interruptActiveTurn. The Claude adapter aborts the running turn before opening a new one for the message, waiting on the turn's terminal result rather than the interrupt acknowledgement, which returns while tools are still unwinding. A CLI that refuses or never settles degrades to the previous steer, so a correction is late rather than lost. Wired to all three entry points: the Follow-up behaviour setting, the per-message modifier, and the arrow on a queued row. Queue is unchanged; the queue's own drain and annotation drops do not interrupt. Stop is untouched and stays a hard session boundary for Claude, as pingdotgg#5891 made it. That makes nativeInterruptAndSend load-bearing rather than an optimisation: adapters that do not declare it take a generic interrupt-then-send in ProviderService, which is only safe where interruptTurn leaves the session alive - Codex, Cursor, OpenCode, Grok, Antigravity. Mobile has no send-now affordance and no Queue/Steer setting. Measured against a real Claude Sonnet 5 session running ping -c 40 through Bash: clicking the arrow mid-tool answered the correction after 35.2s before (the ping's remaining runtime) and 2.1s after, with the turn cut from 51s to 15s. Prepared with Claude Opus 5 in T3 Code.

This brings the arrow in line with Codex, where sending mid-turn interrupts rather than queues behind the current work.
