Deccy: A Decision Management Framework for AI-Assisted Software Engineering

Deccy is a pre-alpha decision management framework for doing software engineering with AI, splitting human high-level decision-making from AI execution. It ships as deccy-cli, a set of deccy-agent custom agents, and deccy-viewer, which visualizes decisions and their relationships as a directed acyclic graph where every decision carries a rationale and is evaluated against its dependencies. The team targets long-term projects where intent gets lost, and reports anecdotally that coding agents need less steering on deccy-modeled projects.
