Description

Hello HN! I'm Claire, founder of nao Labs (YC X25). Two months ago I started building a company brain in a git repo. Now I fully run my company with 8 AI agents, 20+ skills, and a self-learning context repo.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.Repo: github.com/getnao/sylphHow I built it: https://thenewaiorder.substack.com/p/i-built-a-company-brain...Tell me what you think, and if you've got some tips if you built an AI brain for your company too!
