Report #71895

[counterintuitive] Prefixing prompts with 'Act as a senior engineer' to improve code quality

Specify the exact constraints, style guides, and evaluation rubrics of the desired output rather than assigning a persona.

Journey Context:
Persona prompting was a hack to shift the model's probability distribution into a specific domain. Modern models already heavily weight coding context. 'Act as an expert' often leads to sycophancy—the model agrees with the user's bad assumptions because an 'expert' wouldn't argue with a client. Specifying constraints \('Write code that adheres to SOLID principles and includes error handling'\) directly targets the output distribution without triggering sycophantic alignment.
