Plan: answers as narrated walkthroughs

Answers that explain something (a flow through the code, what a change does, how two variants differ) will come as a short walkthrough with slides and narration instead of a block of text. The walkthrough starts playing while the agent is still writing it, and every text answer gets a "Show as walkthrough" button. Slides and player follow showntell's look, with a progress bar in one segment per slide and captions to read along, and Obeya's demo videos take over the same player. This page shows the plan: seven workstreams, what the prototype measured, and the decisions behind it.
