 ## Use

+After installation, the extension registers the `ask_user` tool plus `/ask-settings`, `/answer`, `/answer:again`, and `/ask:replay` commands.
 
 Agents can auto-discover and call `ask_user` when they need clarification instead of guessing. In interactive sessions, it opens a terminal UI flow for structured answers, supports native pi-style `@` file references while typing answers or notes, and returns normalized answers back to the agent. Ask settings are available both from `?` in the ask flow and from the `/ask-settings` command. Behaviour settings are binary `on`/`off` toggles that save immediately; customizable ask keymaps are changed by editing the shown config file path.
 
+### Answer and replay commands
+
+`/answer` is useful when the agent asked questions in plain text instead of using `ask_user`. It extracts questions from the latest completed assistant message and opens the same ask UI.
+
+Replay commands are branch-aware. They read persisted entries from the current pi session branch, so they work naturally with `/resume`, `/tree`, and conversation branching:
+
+- `/answer:again` reopens the latest form created by `/answer` on this branch
+- `/ask:replay` reopens the latest real `ask_user` form on this branch
+
+Cancellation is local to the UI: closing a replayed form does not start a new agent turn. Submitted answers are sent back as a normal user follow-up message.
+
 You can also talk to pi to configure this extension. When asked to customize pi-ask settings or keymaps, the agent is instructed to read the bundled `docs/configuration.md` guide first and then edit the config file accordingly.
 
 This package also bundles the `ask-user` skill profile from `skills/ask-user/SKILL.md`. It reinforces when to use the tool, is enabled by default when installed, and can be disabled via `pi config`. The skill was inspired by https://github.com/edlsh/pi-ask-user.
