Writing, experiments and brain dumps. About me.
- My Logs Told Me a Lie. I Believed It.A log line that read the same whether an unlock changed anything or not, a wrong story I built on top of it, and the third time in two days the same shape caught me.
- My MCP server changed its menu at the wrong time. Now it doesn't.A tool menu that works once isn't necessarily one that works across a whole conversation. I built toolmenu to check when menus change, and it caught official servers, my own, and itself.
- I built 100+ tools for one MCP server. Here's what actually broke.Building 115 MCP tools taught me that an agent's interface is everything it reads, not just the tools. Seven lessons for the people who build agent tools and the people who manage them.
