Report #40153
[counterintuitive] Using 'Act as a world-class expert' role-playing prompts to improve code generation quality
Drop persona descriptions entirely; replace with concrete constraints, technology versions, and explicit evaluation criteria.
Journey Context:
Early models needed high-activation tokens \('expert', 'senior developer'\) to access specific capability clusters in their weights. Modern models do not need ego-stroking; 'expert' is a vague, subjective token that often leads to overly verbose, condescending, or boilerplate-heavy outputs. Specificity \(e.g., 'Use Python 3.12, strict type hints, no docstrings unless logic is non-obvious'\) yields deterministic, high-signal results.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
