###### New Features

- **Fullscreen transcript search** — Search and navigate matches in fullscreen mode. See [TUI Fullscreen Viewport](https://github.com/earendil-works/pi/blob/v0.84.2/packages/coding-agent/docs/keybindings.md#tui-fullscreen-viewport).
- **Configurable default tools** — Choose startup built-in tools globally or per project. See [Tools](https://github.com/earendil-works/pi/blob/v0.84.2/packages/coding-agent/docs/settings.md#tools).
- **Configurable fullscreen exit output** — Print the transcript or only a resume hint on exit. See [Interactive Mode](https://github.com/earendil-works/pi/blob/v0.84.2/packages/coding-agent/docs/usage.md#interactive-mode).

- Added `expandPromptTemplates` to extension `pi.sendUserMessage()` options for explicitly dispatching commands and expanding skills and prompt templates. See [`pi.sendUserMessage()`](https://github.com/earendil-works/pi/blob/v0.84.2/packages/coding-agent/docs/extensions.md#pisendusermessagecontent-options) ([#7857](https://github.com/earendil-works/pi/pull/7857) by [@mrexodia](https://github.com/mrexodia)).
