A systems breakdown of what’s actually inside a coding agent: the agent loop, tool design, memory management, policy layer, and the survival engineering required to make it work on local models via Ollama.
Anatomy of a Coding Agent: What I Learned Building My OwnWorking code without architecture predictably collapses. Learn why AI amplifies architectural chaos, how accidental architecture leads to rewrites, and what hexagonal architecture can do to fix it — with practical steps you can take this week.
Your Code Works. Your Architecture Doesn’t.How a simple 50-line notification system spiraled into architectural chaos in 20 weeks—and why AI coding tools now make this descent 10x faster. A cautionary tale every developer will recognize.
