[synthesis] AI code generation agent produces inconsistent outputs — different frameworks, styles, and patterns across requests

Define an explicit constraint surface \(framework, component library, file conventions, naming patterns\) and encode it as non-negotiable system prompt constraints. Detect the project's existing constraint surface from package.json/tsconfig and enforce it. Never let the model choose its own tech stack per request.

Journey Context:
Unconstrained code generation has combinatorial output explosion — the model might choose React or Vue, CSS modules or Tailwind, fetch or axios, with no consistency. v0 constrains generation to React \+ Tailwind \+ shadcn/ui and produces remarkably consistent output. Cursor's Composer works best when it detects and follows existing project conventions. Devin operates within a shell/filesystem constraint surface. The synthesis: the constraint surface IS the architecture, not a limitation. Each constraint \(e.g., 'always use shadcn/ui components'\) eliminates a dimension of variation, making generation more reliable and outputs composable. Products that let the model freely choose produce code that doesn't compose across turns. The constraint surface must be detected \(from existing code\) or declared \(from project config\), never assumed.
