Bite-sized experiments in agent UX

Streaming text

Generated text restyling as it arrives.

Memory staleness

A memory showing its age.

Context window meter

An ambient sidebar readout of how full the current conversation's context window is — so the diminishing-returns zone is visible before you hit it. Could roll in token cost too, or stay purely about context budget.

Agent thinking

How an agent looks while it works — planning, retrieving, deliberating, hesitating.

Verification surfaces

Quick ways to confirm what an agent did without redoing the work yourself.

Provenance pills

Where a claim came from, attached to the phrase.

Reversibility

Hold-to-confirm gestures keyed to how reversible the action is.

Predictive ghosting

Drag-and-drop reordering usually feels mushy. A ghosted landing slot makes the drop read as deliberate — useful any time precise reordering matters, such as in a human-in-the-loop moment.
