Summary from the TLDR Dev newsletter

Coding agents, or harnesses, are sophisticated systems that wrap LLMs to improve their performance and usability for software development tasks by acting as a control loop that manages repository context, tool access, memory, and efficient prompt construction. This architectural layer enables capabilities like command execution and long-session continuity, making LLMs far more effective in practical coding scenarios.
