Hades – Unity context graph for Claude Code

I brought you my new open source project for Unity and Claude Code to work in pair. Long story short: Claude usually has a hard time navigating Unity projects - complex scenes, nested prefabs, and even GameObjects with dozens of components attached, each with dozens of properties.

Straightforward grep-and-guess is very weak in terms of efficiency, and — most importantly — in terms of reliability. Claude misses the relations between entities in your game, that's the bitter truth. If you're interested in an actual comparison, concrete example: I asked the agent "which prefabs and scenes break if I change EnemyAI?" Stock Claude Code read ~200k tokens of YAML, found 1 prefab, missed 3 variants, and suggested a change that breaks inheritance. With Hades it returned the correct map — 4 prefabs, 3 scenes — in 7 tool calls, 27% cheaper. Full side-by-side with repro: https://github.com/TheArcForge/Hades/blob/main/Documentation...

Since I work with Unity and Claude daily as part of my job, I came up with a solution. Hades builds a graph out of your project's entities, and Claude can query it via MCP tools.

That's the simple version — if you want the details, I wrote up the full story on Medium: https://medium.com/@mike.kuharuk/unity-context-graph-for-cla...

So far I've only proof-tested it on macOS and Unity 6; that scope will grow step by step. Also v1 is mainly built around Claude Code, so Cursor and all other AI agents supports will be added post launch.

I'd appreciate technical feedback and suggestions.
