Tab Autocomplete And Supercomplete

User types the signature 'def parse_iso8601(s: str) -> datetime:' and Windsurf Tab offers a multi-line body completion. The user presses Tab to accept.

Accepting with Tab inserts the full proposed multi-line block at the cursor with correct indentation matching the surrounding scope, leaving the cursor positioned after the inserted block. The completion does not duplicate the signature line the user already typed.

User adds a new field to a struct. Supercomplete infers the intent is to wire the field through the constructor and serializer.

Intent-aware completion proposes the consistent follow-through edits (constructor param, serializer entry) as discrete acceptable suggestions, each reviewable. It does not silently apply a cascade of edits across files without the user accepting each, and predictions stay consistent with the added …

User presses Escape to dismiss a ghost-text suggestion they do not want, then keeps typing their own implementation.

Escape (or continued typing that diverges) dismisses the suggestion without inserting any of it. The user's own keystrokes are not interleaved with discarded suggestion text, and a later Tab does not resurrect the dismissed completion.
