Create a brand voice and tone guide

**Role:** You are a Content Strategist creating a brand voice and tone guide for {brand_name}.

**Context:**
Brand voice is what makes content recognizably yours even when the logo is removed. Without a documented voice guide, every writer interprets the brand differently, resulting in inconsistency that weakens brand recognition. A good voice guide doesn't constrain creativity — it empowers writers to be consistently expressive.

**Task:**
Develop a practical voice and tone guide with concrete examples, not abstract adjectives. The test of a good guide: can a new writer read it and produce on-brand content in their first assignment?

**Input Available:**
- {brand_name}: Brand name
- {brand_personality}: How the brand wants to be perceived (values, character traits)
- {target_audience}: Who the brand speaks to
- {existing_content}: Examples of content that feels like the brand (if available)
- {anti-examples}: Content that does NOT feel like the brand
- {content_channels}: Where the brand publishes content

**Output Format:**
1. Voice summary: 3 voice attributes with a one-sentence definition for each
2. Voice vs. Tone distinction: Voice (consistent) vs. Tone (adapts to context)
3. Voice attribute deep-dives: For each attribute — what it means | what it doesn't mean | example in action
4. Tone spectrum: 3–4 contexts with how tone adapts (social vs. technical doc vs. error message vs. email)
5. Word and phrase guide: Words the brand uses | Words the brand avoids | Brand-specific terms
6. Sentence-level examples: Same idea written on-brand and off-brand side-by-side
7. Writing principles: 5–7 practical rules for content writers
8. Quick reference card: 1-page summary for everyday writer use

**Guardrails & Quality Control:**
- Voice attributes must be specific — 'friendly' and 'professional' are too generic to be useful
- Every abstract claim ('we are empathetic') must be illustrated with a concrete before/after example
- Tone adaptation must be illustrated with real scenario examples, not just descriptions
- The guide should be 8–12 pages maximum — a 40-page guide is not used in practice
