[synthesis] How should an AI agent decompose a large code generation task?

Decompose generation into verifiable, isolated micro-artifacts \(e.g., individual components, single test cases\) and execute them in a sandboxed environment immediately to gather environmental feedback \(compiler errors, render bugs\) before proceeding to the next micro-task.

Journey Context:
Naive agents try to generate an entire application or large file in one LLM call, leading to cascading errors. v0's observable generation process shows it building UIs piece-by-piece, rendering as it goes. Devin's architecture heavily relies on its sandboxed compute environment. The synthesis is that task decomposition is inseparable from execution verification. An agent shouldn't just plan 'write the backend, then the frontend.' It must plan 'write the API endpoint, run the linter, write the test, run the test.' The tradeoff is higher compute overhead for running the sandbox frequently, but it prevents the 'drift and hallucination' that occurs when an agent writes hundreds of lines of code without checking if it even compiles.
