Subagents in Claude Code: Delegating Without Losing Control

The Infinite Context Problem Imagine you ask Claude to investigate how authentication works in your project. It starts reading files. Lots of files. Suddenly you have 50,000 tokens of context filled with code you only needed to consult, not remember. Now every response is slower. And more expensive. And when you want to do something else, all that context is still there, taking up mental space. The solution: subagents. You launch a specialized agent that does the dirty work in its own isolated context, returns a summary, and disappears. Your main conversation stays clean. ...

Skills in Claude Code: Teaching Old Dogs New Tricks

The Problem of Repeating Everything Have you ever had to explain the same thing to someone twenty times? Now imagine that, but with a robot that also loses its memory every few hours. “No, Claude, the commit has to pass tests first.” “Claude, I already told you to use the type: description format.” “Don’t add emojis, damn it!” This was my daily routine until I discovered Skills. In plain English: they’re instructions you write once and Claude follows forever. Like training a dog, but without the treats. ...

Linear and Beads: How to prevent your AI from getting Alzheimer's

The robot’s amnesia Imagine you hire a brilliant programmer. They solve complex problems, write clean code, understand your architecture. But they have one small flaw: every few hours their memory gets wiped. They start from scratch. They don’t remember what they were doing, what you decided together, or why the code is the way it is. Well, that’s exactly what happens with Claude Code and other AI agents. When the context fills up (and it fills up fast if you’re working on a real project), the system does a “compaction.” In plain English: it summarizes the conversation and throws everything else away. The problem is that summary loses nuances, decisions, and especially the state of ongoing tasks. ...
