For one you can ask Pi to create a TUI extension, so along with the agent interface you can add whatever custom TUI you need, such as portfolio stock tickers, alerts, whatever you want.
replyMany of my harnesses eventually turn into customized UIs around the chat interface.
I was doing something similar months ago with openclaw. I had skills/scripts that replaced my todo list, expense tracker, habits, whatever etc and then would create a minimal web ui. Then a deploy skill that wires it up to my docker/traefik setup. This eventually led to a custom chat dashboard with those wired up as widgets.
replyAuthor here. I think our website could be much clearer - but Pi is fundamentally easier to mold than other harnesses. It’s not magic but it strikes the balance well of letting you shape it extensively without letting you break it.
replyA harness is the bottom layer of a pie that gets fed into the model. In my project, I count 7 more layers on top of it https://replicated.live/blog/wiki
They all affect consistency, coherence, token efficiency. Probably we need some broader term. Like "information architecture", "knowledge architecture"? It's not just shoveling Markdown to nvidias, after all.
replyCodex and Claude historically had more bloat in their system prompt and tools. Pi is minimal by design so more adaptable. But to be fair Claude Code is moving in the Pi direction with a small system prompt.
