Pi is now my default coding agent.
It's faster than any other agent I've used.
Its system prompt is small so you really feel the personality of the underlying model.
The tools are few, but usually enough.
It faithfully follows the Agent Skills format.
It's extensible so I can make it my own.
It knows how to read its own source code.
It has built-in support for Cloudflare AI gateway with unified billing, so I can run any model and I don't have to bring any API keys.
Here's a prompt you can use to set up your own gateway: https://gist.githubusercontent.com/zeke/4a6e62478a495228492cda836441a8a9/raw/32bb7fc4d1bcd482358a5715b398d55ec042eca6/pi-cloudflare-ai-gateway-prompt.md
