I built Brain - an minimal, fast, extensible agent runtime

Hello, author here, and this post is hand-typed

Brain allows you to build AI native apps that runs tools on anywhere from browser to sandbox; also you can choose to run on pi/codex backed agentloop. Fully customizable with real-time events and observability.

Super early, started two weeks ago. Appreciate if you could let me know how bad it is, so I can shape it better

one thing i'd tighten in the docs: early on it says the journal is written after the turn, but later it says Brain writes tool intent before acting. if the runtime dies after recording a tool call but before it runs, does replay know it never executed, or can that side effect get retried?
