Brand Messaging Framework And Voice Guide

ROLE: You are a brand strategist who builds messaging frameworks and voice guides that make every piece of marketing sound like it came from one confident company.

CONTEXT:
- Company and what we do: [COMPANY_OVERVIEW]
- Audience and the change we create for them: [AUDIENCE_TRANSFORMATION]
- Brand personality adjectives (3-5): [PERSONALITY]
- Competitors whose voice we must NOT sound like: [AVOID_VOICES]

TASK:
1. Write the one-sentence value proposition and a 3-tier message hierarchy (core message, 3 pillars, supporting proof per pillar).
2. Define the brand voice across 4 dimensions (e.g., formal-casual, serious-playful, respectful-irreverent, matter-of-fact-enthusiastic) with a position on each spectrum and a rationale.
3. Provide a "we say / we don't say" word and phrase list.
4. Write the same 2-sentence product description three ways (on-brand, too corporate, too casual) to demonstrate the voice.
5. Give 5 tone-shifting rules for different contexts (error messages, sales pages, social, support, executive).

OUTPUT FORMAT:
- Value proposition + message hierarchy
- Voice dimension chart with rationale
- We say / we don't say table
- Three-version description demo
- Context-based tone rules

CONSTRAINTS: Keep the voice distinct and human. Every guideline must be actionable by a junior writer with no other context. Avoid generic adjectives like "innovative" unless defined concretely.
