Report #75498

[counterintuitive] Using elaborate persona prompts like 'Act as a world-class senior software engineer' to boost coding performance

Specify the exact context, constraints, and target environment \(e.g., Target Python 3.11, use Pydantic V2, optimize for low latency\) rather than assigning a persona.

Journey Context:
Role-playing was useful for early models to activate specific latent spaces \(e.g., act as a Python expert loaded Python syntax\). Modern models already possess strong baseline coding capabilities; act as an expert wastes tokens and often backfires by making the model overly verbose, pedantic, or sycophantic, ignoring actual constraints. Context and constraints are the real expert triggers for modern RLHF-tuned models.
