Define rules once, then sync them everywhere + share with others with 'aligntrue sync'. It has solo and team modes, and supports 20+ agent formats (Cursor, AGENTS.md, CLAUDE.md, etc).
Problem it solves: If you use multiple agents, work with other people using agents, etc. it's hard to keep them in sync + manage changes, so this solves it. It also lets you use rules from other repos as a source and push rules to a remote, e.g. if you want to use personal/private rules on a team without committing them to the team repo.
It has experimental customization support for plugs and overlays, which enable you or others to customize your stack, commands, overlay preferences, etc. Team rules get synced along with any other rule sources, they get merged at export time to selected agent formats (Cursor, AGENTS.md, CLAUDE.md, etc.) and any personal preferences take precedence.
I built this to scratch my own itch and spent a ton of time (maybe obsessively) crafting the experience to work well across various agent types, so I hope it's as useful to you as it is to me. Feedback welcome!
