# Brand Voice Consistency Checker

## Purpose
Score a piece of content against a brand's defined voice and positioning, flag every specific deviation with the exact offending line, and hand back ready-to-use rewrites — so content from freelancers, distributed teams, and agencies publishes on-brand without a manual line-by-line review.

## When to Use
Invoke this skill when the user asks to:
- Check whether a draft matches the brand voice or tone guidelines
- Review content from freelancers, agencies, or distributed writers before publishing
- Audit copy for off-brand language, tone drift, or positioning inconsistencies
- Get suggested rewrites to bring a piece back on-brand
- Score content against a brand style guide or voice charter
- Spot-check a batch of content for voice consistency across contributors

## Inputs Required
Before starting, collect:
- **Content to review**: The full draft, copy, or content piece (any length or format)
- **Voice guidelines**: The brand's voice charter, tone rules, or style guide — however documented
- **Voice adjectives**: 3–5 words describing how the brand should sound (e.g., warm, confident, plainspoken)
- **What to avoid**: Words, phrases, tones, or clichés explicitly off-limits for the brand
- **Positioning statement**: The core value proposition or category claim the brand owns
- **Content type**: Where this will run — web, email, social, blog, product, ad

If a formal voice charter is missing, infer working voice principles from the voice adjectives and positioning, and state which principles were inferred.

## Instructions

### Step 1: Establish the Voice Baseline
Before reviewing, translate the guidelines into a scoring rubric across 6 voice dimensions:
- **Tone** — the emotional register (warm vs. authoritative vs. playful)
- **Vocabulary** — word choice, jargon level, brand-specific terms, banned words
- **Sentence structure** — rhythm, length, formality, use of fragments
- **Point of view** — first/second/third person, how the reader is addressed
- **Positioning alignment** — whether claims match the brand's owned position
- **Personality markers** — signature phrasings, humor, directness, or restraint the brand is known for

For each dimension, note in one line what "on-brand" looks like based on the inputs.

### Step 2: Score the Content Across the 6 Dimensions
Rate each dimension 1–5 (5 = fully on-brand). For each score, give one sentence of evidence citing the content. Produce an overall voice consistency score as a percentage (average of the six, converted to a 0–100 scale).

### Step 3: Flag Every Inconsistency
Walk the content top to bottom. For each deviation, log a flag with:
- **The exact line or phrase** (quoted verbatim)
- **Dimension violated** (which of the 6)
- **Severity**: High (contradicts positioning or breaks a hard rule) / Medium (noticeably off-tone) / Low (minor polish)
- **Why it's off-brand** in one sentence tied to the guidelines

Do not soften or skip flags to be polite — flag everything, then let severity communicate priority.

### Step 4: Deliver Rewrites for High and Medium Flags
For every High and Medium flag, provide a rewritten version of that line or passage that resolves the issue while preserving the writer's intended meaning. Rewrites must be drop-in ready — no brackets, no placeholders. Keep Low flags as a quick-fix list without full rewrites.

### Step 5: Positioning Gut-Check
Separately confirm the piece reinforces — and never undercuts — the brand's positioning statement. Flag any claim that dilutes, contradicts, or wanders from the owned category position, even if the tone reads fine.

### Step 6: Summary Verdict
Give a clear publish decision: **Ready as-is / Ready after listed fixes / Needs a rewrite pass**. State the single most important change the writer should internalize for next time.

## Output Format
- **Structure**: Voice baseline → dimension scorecard → flagged inconsistencies → rewrites → positioning check → verdict
- **Length**: 700–1,100 words (scales with content length)
- **Format**: Scorecard as a table; flags as structured bullets with quoted lines; rewrites shown as before/after
- **Sections**: Overall Score → 6-Dimension Scorecard → Flagged Inconsistencies → Suggested Rewrites → Positioning Check → Verdict
- **Tone**: Editorial director reviewing a contributor — direct, specific, evidence-led, never vague

## Quality Checklist
Before delivering output, verify:
- [ ] All 6 voice dimensions are scored 1–5 with cited evidence for each
- [ ] An overall consistency percentage is calculated and shown
- [ ] Every flag quotes the exact offending line verbatim — no paraphrasing
- [ ] Each flag has a severity label (High/Medium/Low) and dimension tag
- [ ] Every High and Medium flag has a drop-in rewrite with no placeholders
- [ ] A clear publish verdict is stated (not hedged)

## Notes
- The most common failure across distributed teams is tone drift, not banned words — writers stay technically compliant while losing the brand's feel; weight tone and personality markers accordingly
- When a voice charter is thin, the "words to avoid" list is often the highest-signal input — writers reveal the brand more clearly by what they'd never say
- Positioning contradictions are the most expensive errors and the least visible; a piece can score high on tone and still undercut the brand's core claim — always run the positioning gut-check independently of the tone score
