Pages, files and charts
Replies can be more than text.
Pages
The agent can make an HTML page: a report, a one-pager, a dashboard. In the app it opens in the panel beside the chat; in the terminal it is a file row you open in your browser. When you ask for a change, the agent edits the page in place instead of starting over.
Files
The agent can save a PDF or a Markdown file, and keep a file an app returned. Every file of a chat (including the ones you attached) is listed under /files; /open opens the last one and /save saves a copy to your Downloads folder, never over an existing file. In print mode, --save-files DIR downloads them.
You can attach files to a message in the app and ask about them; spreadsheets can be cleaned and deduplicated.
Tables, metrics and charts
The agent can show a table, a row of metrics (a label, a value and its change), or a chart, right in the chat. The terminal draws tables and metrics as text and summarizes a chart in one line; the chart itself is in the app.
