Very cool setup. I went down a similar path and while it is definitely cool to see the extent of how agentic AI can be, I agree the ROI isn't _quite_ there yet.
I don't live in a world where I need to be constantly reading and replying to emails, so 95% of my inbox is just subscription spam. With development I need to be at the helm to design the planning requirements and actively make decisions before the agent goes off and executes the plan. But I don't need a personal agent for that, I work directly out of codex/claude-code.
I've landed on a similar conclusion building a much narrower tool: for messaging specifically, I don't think people want an agent that reads and sends on their behalf — they want the drafting to be fast, not the sending to be automatic. The moment you take the human out of the send button, the failure modes (wrong tone, made-up facts) become a lot more costly. Scoping down to "give me two good drafts, I'll pick and edit" turned out to be more useful day-to-day than anything closer to full autonomy.
