Report #48688

[counterintuitive] Prefixing prompts with 'Act as a senior software engineer' to get better code

Specify the exact context, constraints, and target environment \(e.g., 'Target a low-latency Go microservice using gRPC'\) instead of assigning a persona.

Journey Context:
Persona prompts worked when models needed alignment to a specific distribution of text. Now, they often introduce stylistic fluff \('Ah, as an expert...'\) without improving factual accuracy or code quality. Contextual constraints directly condition the output distribution on what actually matters for the code, avoiding the sycophancy and verbosity triggered by role-playing. The model already has expert knowledge; it needs your constraints.
