Report #69295

[synthesis] Agent implements hyper-abstracted, useless code after retrieving multiple similar patterns from RAG

Constrain RAG retrieval to top-1 or top-2 results, and explicitly prompt the agent: 'Implement only the specific requirement. Do not generalize or create factory patterns unless explicitly requested.'

Journey Context:
When an agent queries a vector database for a solution, retrieving 5 similar but distinct code snippets triggers its training bias towards abstraction. It synthesizes a generic interface or factory pattern that accommodates all 5 snippets but solves the actual prompt poorly. The partial success of 'the code compiles and looks professional' masks the total failure of 'it doesn't do what was asked.' The synthesis is that RAG context injection biases the agent towards pattern-matching retrieved abstractions rather than solving the minimal specific prompt.
