I built it in a git repo because I refused to lock into any tool - not a context layer, not a specific agent harness. Today I'm open sourcing it so others can build their own.
Sylph is the open source version of the company brain I use. It gives you the structure to host your own company context, build skills, create AI agents, and already has a self-learning loop scaffolded. It is a Git repo, with no lock-in on any tool, that can work with any agent: Claude Code, Codex, Cursor.
Sylph is made for you to make your own: fork it, run /sylph-setup, and it will build your own company brain according to your own context.

Tell me what you think, and if you've got some tips if you built an AI brain for your company too!
