Essay argues agentic coding tools are turning code into malleable 'clay'
In a Sep 25, 2026 post titled 'Code is clay now,' writer Alberto Denia argues that agentic coding tools have drastically lowered the cost of changing code, making it behave more like clay than stone. He describes this as enabling a 'modeling' approach to building software, where developers sketch rough versions and iteratively reshape them rather than planning meticulously upfront.
GoKawiil's interpretation of the reporting above, not reported fact.
The analogy suggests that as AI coding assistants reduce the friction of making changes, development workflows could shift from careful upfront planning toward rapid prototyping and iteration. Denia cautions that this ease of change doesn't replace engineering judgment—teams still need to assess whether changes are correct, or risk accumulating unstructured, unstable code.
- Agentic coding tools have made editing code dramatically cheaper and faster, per the author.
- The piece proposes a 'modeling' workflow: rough-sketch first, refine iteratively, rather than detailed upfront planning.
- The author warns that low-cost changes don't eliminate the need for product and engineering judgment to avoid messy, unstable results.
