Report #86135
[counterintuitive] Using 'Act as an expert senior developer' to improve code generation quality
Drop persona prompts; specify exact technical constraints, style guides, and anti-patterns to avoid.
Journey Context:
Role-playing prompts add token bloat and often trigger sycophancy, where the model adopts a confident, explanatory tone rather than strictly following technical constraints. Modern models are heavily post-trained for helpfulness and accuracy; telling them to be an 'expert' does not inject missing knowledge. Specifying constraints like 'use functional components, no classes' directly constrains the output distribution, which is the actual mechanism for improving code quality.
