Ask AI, the live chat on dhseadev.online, stopped answering after Groq retired its model, while the health check kept saying ok. What broke, the fix, and what to…

How the DHSeaDev arcade adds a game: one folder, one row, and checks with no exemptions. What they caught when Mosslight arrived, and what they still miss.

How MCP servers, plugins, skills and prompt caching change Claude token use, checked against Claude’s own docs, and why tokens still miss human effort.

Creature Camp is now on itch.io, free. The whole game is one HTML file of about 240 KB that never contacts a server — the same build that…

I merged 89 Claude skills into 38 without deleting a rule. What the post-install review found, how the system grades, and what is still not done.

Creature Camp is a Chrome side-panel game whose art is a program rather than a folder of pictures. Twenty-five species, ten hats, five scenes and every expression are…

The dhseadev.online homepage is now one scroll-driven canvas: a prism splitting into eight scenes, a ship escaping a black hole, and no libraries.

CoderLegion interviewed me for their Developer Stories series. I ran the questions through an AI first, deleted all of it, and typed the answers myself.
