A [pi-coding-agent](https://github.com/earendil-works/pi-coding-agent) extension that dynamically registers [Croft AI](https://crof.ai) as an OpenAI-compatible model provider. On startup it fetches the current model catalog from the Croft AI API and makes every available model selectable inside pi — no manual model list to maintain
