## Description This feature proposal aims to improve the perceived performance of code suggestions by introducing preemptive requests and client-side caching. The overall flow would be: - When the user starts a new line and types the first character, fire a code suggestion request preemptively and cache response - If the user pauses typing for >300ms, first check if the cached suggestions match the current line content - If there is a match, show the cached suggestions immediately instead of making a new network request - If no match, clear cache and fetch updated suggestions Benefits: - Perceived performance boost by leveraging caching - Avoid network round trip for unchanged suggestions - Clear stale cache automatically on content change To implement: - Fire background prefetch request on line start - Cache response - Check cache first when suggestions triggered - Invalidate cache entry if line content changes
