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

Specify the exact constraints, tech stack, and evaluation criteria of the domain instead of assigning a persona. Replace 'Act as an expert in X' with 'Use X, ensuring Y constraint and Z architecture.'

Journey Context:
Persona prompting worked well on earlier models to activate specific latent spaces \(e.g., loading Python syntax weights\). Modern models have deeply integrated coding capabilities; persona prompts now often backfire by introducing stereotypical fluff \('As a senior engineer, I believe...'\) or conflicting instructions. What actually shifts the model's behavior is defining the environment and rules. Direct constraints directly alter the probability distribution of the code generated, whereas personas just add noise.
