Field note
DeepakNess published a tiny Pi coding-agent extension that replaces the plain working indicator with rotating phrases, colors, and decorative symbols. It chooses a new phrase every two seconds, avoids repeating the same phrase or color consecutively, and clears the status when the turn ends.
The extension is a TypeScript file placed at ~/.pi/agent/extensions/whimsical.ts; Pi loads it on startup. The linked implementation contains hundreds of verbs and jokes. It changes the terminal experience only: there is no new model behavior, tool access, memory, or execution capability.
That boundary is the entire point of this brief. Agent ecosystems are becoming extensible down to their waiting states, but cosmetic extensions should be described proportionately. This is a useful developer-experience tweak for people who enjoy it, not evidence of a new runtime or a major Pi release.
