AI coding agents waste most of their context window grepping files and guessing at code structure. Constellation gives them a persistent, team-wide knowledge graph of your codebase (symbol search, dependency graphs, impact analysis) delivered via MCP so every token goes toward reasoning, not discovery.

    tells you what to do

    Compared with ALL older versions of software especially both Linux Office tells you what to do instead of performing what you ask for step by step. I often cannot find the way to repair what I did where in Windows this goes fine or is easy to correct. Beside that Open Office is very slow compared with Libre Office and Microsoft is still the fastest.
