Good LLM Dev and Usage Patterns

Introduction

This is a list of patterns regarding usage of LLMs (Large Language Models) that I’ve observed result in positive outcomes. I’ve split them into two categories:

  • Usage, for patterns used in systems that are partly agentic, i.e. the system utilizes LLMs during its operation. The examples given are focused on coding agents, but they are generally applicable.
  • Development, for patterns used during software development

If the category split feels arbitrary, feel free to ignore the (ir)relevant headings.
