### Noise Audit Table | Element | Classification | Reason | |---|---|---| | 'helpful, friendly, and enthusiastic' | NOISE | Persona bloat — irrelevant to email output quality | | 'Make sure the email is professional' (repeated 4x) | NOISE | Redundant Restatement pattern — one instance is signal, rest are noise | | 'not too long or too short' | WEAK SIGNAL | Vague — replace with word count constraint | | 'email their boss about taking a day off next Friday' | SIGNAL | Core task definition | | 'polite and not too demanding' | SIGNAL | Tone constraint | | 'greeting and sign-off' | SIGNAL | Structural requirement | ### Noise Patterns Detected - Redundant Restatement (professional × 4) - Hedge Stacking ('not too long or too short') - Irrelevant Persona Detail ('enthusiastic,' 'loves helping') ### Core Signal Elements 1. Write a professional business email 2. Recipient: the user's direct manager 3. Subject: requesting Friday off 4. Tone: polite, non-demanding 5. Structure: greeting, body, sign-off 6. Length: 80–120 words ### Optimized Prompt Write a professional email to a direct manager requesting next Friday as a day off. Tone: polite and non-demanding. Structure: formal greeting, one-paragraph body, professional sign-off. Length: 80–120 words. ### Accuracy Delta Estimate Score: 8/10 — Eliminating four redundant 'professional' cues removes conflicting emphasis signals that cause models to over-formalize tone at the expense of warmth and clarity.
