Report #78732

[synthesis] Agent stops writing comprehensive code \(skipping tests or error handling\) despite explicit instructions

Track the ratio of boilerplate/scaffolding code to core logic in agent outputs. If the ratio drops, inject dynamic few-shot examples of complete implementations into the prompt, or append a 'do not skip steps' enforcement token at the end of the prompt.

Journey Context:
Model providers frequently update RLHF to make models more helpful and concise. In a coding agent, 'concise' is catastrophic—it means skipping error handling, omitting imports, or writing '// ... rest of code here'. The agent doesn't fail; it just produces lower-quality, fragile code. Teams think the prompt broke, but it's actually a model weight shift favoring brevity. Monitoring code completeness \(AST node counts, test presence\) catches this before users complain about fragile generations.
