Nano Agent, Mega Senses: Adding LSP to the 260-Line Coding Agent The original nanocode idea is easy to lose in the hype: a coding agent is mostly a loop. You send prompt plus tool definitions to the model; the model answers with text or tool calls; you execute…

Coding agents are innovating fast, but they're also getting bloated. To actually understand what they’re doing, you have to go back to the basics. A good way to learn is to get into it.

Someone has been trying to fix my Windows machine for ages now.. little can I convince them... there are other OS in the world too buddy. 😀

i'll say you beat me to it. with a deliberate excuse. "..I was in meetings.. ", but you know what, look at this way.
Thats how simple all of this is! and easy to get to. A great starting point. thanks for sharing!

What I learned building an opinionated and minimal coding agent Lessons I learned while building my own coding agent from scratch.

An interesting read, if you want to understand coding agents or building one yourself.. its on my #TODO for sure. 😀

Two Essential Patterns for Building MCP Servers When building Model Context Protocol (MCP) servers, I learned two critical design patterns the hard way. What started as a straightforward implementation of a Keycloak administration server quickly…

When I started building my first MCP server, I had a tool explosion to the point where the tool would tell me I was over the limit. This made me restructure the bits. Here are two patterns that I used
