[synthesis] Agent hallucinates non-existent dependencies due to premature code abstraction

Force agents to write monolithic, inline code first, and only introduce abstractions \(imports, classes, separate files\) after a functional baseline is verified to exist and run.

Journey Context:
When asked to build a complex feature, agents often start by creating highly abstracted structures—importing libraries, defining interfaces, and splitting code into modules. Because the agent is predicting the next token, it prefers syntactically clean abstractions. However, it frequently hallucinates import names or assumes methods exist in its mental model of the dependency. When the code fails, the error is buried in an import or module resolution step, and the agent gets lost trying to fix the dependency rather than the logic. Writing 'ugly' inline code first forces the agent to rely only on standard, verified primitives, grounding its reasoning in what actually executes.
