Once AI lowers the cost of execution, the scarcer skill becomes planning, judgment, and knowing what should happen first.

I turned LINE into a remote control for AI. One message from outside, and the AI on my computer gets to work and sends the result back.

I built myself a Facebook-post Skill. It is not just a prompt, but a full workflow with scripts, style memory, and image generation.

After using ChatGPT Pro, Claude Code Max, and Google AI Pro side by side for over a year, I no longer think of them as interchangeable.

The tool I keep using every day is not the loudest agent platform, but Claude Cowork. What stands out to me is not only what it can do, but how well it handles context.
