Moldable development is the integration plane AI codegen is missing

Claude Code, Gemini Code, Pi-Agent — every AI coding tool runs on bash. Bash is the integration plane.

The observation is that the integration plane is seventies technology, and that this is the problem rather than the solution. Bash composes by convention and by convention alone: no types, no schema, nothing that can be checked before it runs.

Moldable development is the next generation of that plane — programmable, inspectable and observable. The difference is not that it is more capable but that it can be examined. A layer can be lifted off and looked at, which is the difference between a system you operate and one you merely hope about.
