Fonteyne describes recurring friction in analytical work: spreadsheets become fragile, notebooks require programming, and general chat tools can answer without enough understanding of the underlying data. Orion aims to let owners and analysts investigate business questions while inspecting the calculations and evidence behind the result.[2]
Contributions
Keep an analytical workspace inspectable
Orion combines conversation with files and analytical tools. Its local-first workspace is designed to keep users in control of their source data and their choice of external models. The product overview describes connecting information from spreadsheets, databases and business systems into a report that can be explored and shared.[2][6]
Share skills across coding agents
Unity maintains canonical skill and rule directories at user and project scopes and mirrors them into supported agents’ locations. Its watcher can also pull changes back from those mirrors before distributing them again. This addresses the configuration drift that appears when a developer switches among coding assistants.[3]
