Method dispatchNextTool

internal/tui/model.go:1053–1061

dispatchNextTool pops the next pending tool call and runs it. Every tool flows through runToolCall; none are special-cased. lastToolKey records this call's target so the failure nudge can tell when the model keeps retrying the same failing operation (see recordToolOutcome).

// dispatch the next pending tool call, or, if none, finalize the turn and
// hand control back. A turn ends precisely when the assistant emits no tool
// calls; there is no loop tool to land on.
