dialog-tree

Maintain a visual "dialog tree" — a data file plus a self-contained HTML viewer in the project repo that map the branches of a long conversation (user questions → the steps/variants of the answers) as an interactive tree with resolve/delete marks and a "built up to" marker for incremental updates. Use whenever the user asks to "create/set up a dialog tree", "update the tree", "add this to the tree", "show open branches", or mentions dialog-tree.html — and proactively offer it when a deep-dive discussion branches enough that the user risks losing track of unexplored side-threads.
