AI coding Agents like Claude Code , OpenAI Codex , and Gemini CLI have disrupted how software engineering is done. IMHO, the most disruptive agents are Claude code and Codex. However, a lot of things already happened, some progress has been made, and there is some evolution in the space. We saw the birth of custom and subagents to avoid passing the whole context window down, custom commands to have more control over a workflow, or when a specific task is executed. Hooks add more determinism and make sure tests and linters are executed as part of the guardrails. From the explosion of MCPs to Multi-Agent Systems. There are many interesting changes and evolutions happened, we learned somethings while some things are still to be learned. For this blog post, I will cover some of the evolution in AI coding agents (mainly around Claude code). I did a lot of POC with agents, 74 Agent-related POCs at the moment. One thing I keep saying is that POCs are getting expensive, now not ...
