The past five years defined developer-AI interaction through the 'Tab' key, where models predict the next line and humans decide. GitHub Copilot perfected this but locked many into a limited mindset. The real shift from 2024 to 2026 is the emergence of autonomous coding agents that can plan, execute, and verify tasks. This article breaks down the core principles behind these agents, from context management to tool use, and provides runnable code examples. It's a valuable resource for engineers looking to understand the architecture of modern AI coding tools or build their own. The content bridges theory and practice, making it accessible yet technically rigorous.
Explore how AI coding evolved from autocomplete to autonomous agents, with practical insights for building and using these tools.
