Clarify First

Before building the guidelines, confirm these inputs. If any is unknown or vague, ASK — do not assume:

• [ ] Brand foundation — purpose, values, and brand promise (the strategic layer every voice and visual choice traces back to)
• [ ] Brand archetype/personality — Expert / Guide / Innovator / Friend / etc. (sets voice attributes and tone calibration)
• [ ] Existing visual assets — current colors, fonts, and logo, if any (determines build-new vs document-existing)
• [ ] Channels in scope — web, email, social, sales, support (drives which cross-channel application sections to produce)

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.

Quick Start

Create Brand Guidelines from Scratch

• Define brand foundation (purpose, values, personality)
• Establish voice and tone system with attribute matrix
• Build visual identity system (colors, typography, logo rules)
• Document imagery and photography standards
• Create channel-specific application guides
• Compile into shareable brand guidelines document

Audit Existing Brand Consistency

• Collect samples from every active channel and touchpoint
• Run the Brand Audit Checklist against each sample
• Score consistency across all seven brand dimensions
• Document deviations with specific remediation recommendations
• Prioritize fixes by customer-facing visibility

Core Workflows

Workflow 1: Build a Brand Identity System

Step 1: Define Brand Foundation

## Brand Foundation
- Purpose: [Why the brand exists beyond revenue]
- Vision: [What the brand aspires to achieve in the world]
- Mission: [How the brand delivers on its purpose daily]
- Values (3-5):
  1. [Value]: [What it means in practice, not just the word]
  2. [Value]: [Behavioral definition]
  3. [Value]: [Behavioral definition]
- Brand Promise: [The single commitment to customers]

Step 2: Establish Brand Personality

Select 3-5 personality traits from the archetype framework:

| Archetype | Personality Traits | Voice Characteristics | Best For |

|-----------|-------------------|----------------------|----------|

| Expert | Knowledgeable, precise, authoritative | Data-driven, technical depth, confidence | B2B, enterprise, professional services |

| Guide | Helpful, clear, patient | Instructional, encouraging, step-by-step | Education, SaaS, healthcare |

| Innovator | Bold, forward-thinking, disruptive | Visionary, provocative, future-focused | Tech, startups, R&D |

| Friend | Warm, approachable, genuine | Conversational, inclusive, casual | Consumer brands, community, lifestyle |

| Motivator | Inspiring, energetic, empowering | Action-oriented, ambitious, rallying | Fitness, coaching, personal development |

| Challenger | Direct, honest, contrarian | Opinionated, confident, questioning | Fintech, disruptor brands |

| Creator | Imaginative, expressive, original | Storytelling, vivid imagery, playful | Design, media, entertainment |

Step 3: Document Voice and Tone

See the Voice and Tone System section below for the complete framework.

Step 4: Build Visual Identity

See the Visual Identity System section below for the complete framework.

Step 5: Create Application Guide

Document how guidelines apply to each channel:

• Website and product UI
• Email marketing
• Social media (per platform)
• Sales materials
• Customer support communications
• Press and media
• Co-branded materials

Workflow 2: Brand Audit

Step 1: Collect Samples

Gather 3-5 samples from each active channel:

• Website pages (homepage, product, blog, about)
• Email campaigns (marketing, transactional, support)
• Social media posts (per platform)
• Sales decks and proposals
• Customer support responses
• Advertising creative
• Physical materials (if applicable)

Step 2: Score Against Seven Dimensions

For each sample, score 1-5 on:

| Dimension | 1 (Poor) | 3 (Adequate) | 5 (Excellent) |

|-----------|----------|---------------|----------------|

| Color usage | Off-brand colors present | Mostly correct, minor deviations | Perfect palette adherence |

| Typography | Wrong fonts used | Correct fonts, inconsistent sizing | Perfect type hierarchy |

| Logo usage | Incorrect sizing, placement, or modification | Mostly correct with minor issues | Perfect logo application |

| Voice consistency | Tone shifts dramatically between sections | Generally consistent, occasional drift | Voice is unmistakably on-brand |

| Imagery style | Stock photos inconsistent with brand | Mostly aligned, some off-brand choices | Cohesive visual language |

| Layout patterns | No recognizable brand patterns | Some consistent elements | Clear, repeated brand patterns |

| Content quality | Errors, vague claims, inconsistent formatting | Clean, generally well-written | Precise, specific, error-free |

Step 3: Generate Audit Report

## Brand Audit Report: [Brand Name]
Date: [Date]
Auditor: [Name]

### Overall Score: [X/35]

### Dimension Scores
| Dimension | Score | Priority |
|-----------|-------|----------|
| Color | X/5 | [High/Medium/Low] |
| Typography | X/5 | [High/Medium/Low] |
| Logo | X/5 | [High/Medium/Low] |
| Voice | X/5 | [High/Medium/Low] |
| Imagery | X/5 | [High/Medium/Low] |
| Layout | X/5 | [High/Medium/Low] |
| Content | X/5 | [High/Medium/Low] |

### Critical Issues
[Specific deviations with exact references]

### Recommendations
[Prioritized fixes with implementation guidance]

Brand Identity Dimensions

Dimension 1: Brand Foundation

The strategic layer that everything else builds on:

• Purpose — Why the brand exists (not "to make money")
• Values — What the brand believes and practices
• Positioning — Where the brand sits in the competitive landscape
• Promise — The core commitment to customers

Dimension 2: Voice and Tone

How the brand communicates across all written and spoken channels. See detailed framework below.

Dimension 3: Visual Identity

Colors, typography, logo, imagery, and layout patterns. See detailed framework below.

Dimension 4: Verbal Identity

Specific language choices:

• Naming conventions — How products, features, and tiers are named
• Terminology — Preferred terms vs. avoided terms
• Taglines and slogans — Core messaging lines
• Boilerplate copy — Standard company descriptions for press, bios, footers

Dimension 5: Experiential Identity

How the brand feels in interaction:

• UI patterns — Consistent interaction patterns in product
• Service tone — How support and success teams communicate
• Onboarding experience — First impression and initial value delivery
• Physical presence — Office, events, swag, packaging

Voice and Tone System

Voice vs. Tone

Voice is consistent — it is who the brand is. It does not change.

Tone adapts — it adjusts based on context, audience, and situation.

Example: A brand's voice is always "clear and confident." But the tone shifts:

• Product announcement: enthusiastic, forward-looking
• Incident response: calm, transparent, accountable
• Tutorial: patient, encouraging, precise

Voice Attribute Matrix

Define 3-5 voice attributes with spectrum positions:

| Attribute | We Are | We Are Not |

|-----------|--------|------------|

| [e.g., Direct] | We get to the point. We say what we mean. | We are not blunt or dismissive. We are not rude. |

| [e.g., Knowledgeable] | We share expertise with confidence. | We are not condescending. We do not lecture. |

| [e.g., Human] | We write like people, not corporations. | We are not unprofessional. We do not use slang carelessly. |

Tone Calibration by Context

| Context | Formality | Energy | Technical Depth |

|---------|-----------|--------|-----------------|

| Marketing homepage | Medium | High | Low |

| Product documentation | Medium-High | Neutral | High |

| Blog posts | Medium-Low | Medium | Medium |

| Error messages | Medium | Calm | Low |

| Social media | Low-Medium | High | Low |

| Sales proposals | High | Medium | Medium-High |

| Customer support | Medium | Warm | Varies |

| Incident reports | High | Calm | High |

Writing Style Rules

Grammar and Mechanics:

• Oxford comma: [Yes/No]
• Contractions: [When to use/avoid]
• Sentence case vs. Title Case for headings: [Standard]
• Number formatting: [Spell out 1-9, numerals for 10+]

Brand Audit Framework

Quick Audit Checklist

Run this against any brand asset in under 5 minutes:

• [ ] Colors match approved palette exactly (no approximate matches)
• [ ] Fonts are correct typeface, weight, and size
• [ ] Logo has proper clear space and is an approved variation
• [ ] Body text meets minimum size and contrast requirements
• [ ] Imagery style matches brand photography/illustration standards
• [ ] Tone matches brand voice attributes for this context
• [ ] No prohibited uses present (stretched logos, unapproved colors, off-brand imagery)
• [ ] Co-branding follows partner logo rules (if applicable)
• [ ] Content is free of spelling, grammar, and factual errors
• [ ] CTAs use approved language and styling

Full Audit Process

For a comprehensive brand audit across the organization:

• Inventory — List every customer-facing touchpoint
• Sample — Collect 3-5 recent examples from each touchpoint
• Score — Rate each sample across all seven dimensions (1-5)
• Analyze — Identify patterns in where consistency breaks down
• Prioritize — Rank fixes by customer visibility and business impact
• Remediate — Create specific fix instructions for each issue
• Govern — Establish review process to prevent future drift

Cross-Channel Application

Website

• Homepage reflects full brand identity (all dimensions)
• Product pages maintain visual consistency with marketing pages
• Blog uses the same typography and color system
• Error pages and empty states still reflect brand personality
• Favicon and OG images use approved logo variations

Email

• Header uses approved logo at correct size
• Color palette limited to brand palette
• CTA buttons match brand primary color
• Font stack includes web-safe fallbacks that approximate brand fonts
• Footer includes consistent boilerplate and legal text

Social Media

| Platform | Avatar | Cover/Banner | Post Templates | Voice Adaptation |

|----------|--------|-------------|---------------|-----------------|

| LinkedIn | Logo icon | Brand banner | Professional, clean | Slightly more formal |

| Twitter/X | Logo icon | Brand banner | Concise, punchy | Slightly more casual |

| Instagram | Logo icon | N/A | Visual-first, on-brand colors | Visual storytelling emphasis |

| YouTube | Logo icon | Brand banner | Thumbnail template | Conversational |

Sales Materials

• Slide deck template with locked master slides
• Proposal template with approved cover page and footer
• One-pager template for leave-behinds
• All use approved color palette, typography, and logo placement

Customer Support

• Email signatures follow standard format
• Help center articles use brand voice (helpful, patient, clear)
• Chatbot responses match brand personality
• Escalation templates maintain professional but warm tone

Best Practices

• Specificity over subjectivity — "Use #2563EB for primary buttons" is enforceable. "Use a nice blue" is not. Every guideline should be specific enough that a contractor produces on-brand work without guessing.

• Show examples of what NOT to do — For every rule, include a clear violation example. People learn faster from anti-patterns than from rules.

• Version and date everything — Brand guidelines evolve. Version every update and keep a changelog.

• Distribute in a usable format — A 200-page PDF nobody reads is worse than a 10-page living document everyone references. Make guidelines accessible where people work.

• Audit quarterly — Brand drift happens slowly. Schedule quarterly audits to catch deviations before they compound.

• Provide templates, not just rules — Every channel should have a ready-to-use template that embodies the guidelines. Templates enforce consistency better than documentation.

• Define escalation for edge cases — Who approves a new color? Who decides if a co-branding request is acceptable? Document the decision process.

• Train new team members — Brand guidelines are only as effective as the people who follow them. Include guidelines in onboarding.

Integration Points

• Brand Strategist — Use for high-level brand positioning and architecture decisions. Brand Guidelines implements and documents those strategic decisions.
• Copywriting — Use brand voice and tone system when writing any marketing copy.
• Content Creator — Reference brand guidelines for every content piece to maintain consistency.
• Social Content — Apply platform-specific brand adaptations from the cross-channel guide.
• Ad Creative — Reference visual identity and voice standards for all advertising creative.
• Landing Page Generator — Apply brand colors, typography, and voice to all landing pages.

Troubleshooting

| Symptom | Likely Cause | Resolution |

|---------|-------------|------------|

| Brand colors look different across web and print | RGB vs CMYK color space mismatch; no Pantone reference defined | Document colors in all three systems (Hex/RGB for digital, CMYK for print, Pantone for exact matching) |

| Teams consistently use wrong fonts | Font files not distributed or licensed for all team members | Create a shared font kit, document web-safe fallbacks, include licensing status per font |

| Logo appears stretched or pixelated on partner sites | Co-branding guidelines not shared or minimum size not enforced | Distribute logo kit with vector formats (SVG/EPS), document minimum sizes and clear space rules |

| Voice varies dramatically across customer support vs marketing | Tone calibration by context not documented or not trained | Create channel-specific tone guides with before/after examples, include in onboarding |

| Brand drift detected in quarterly audit | No governance process for new assets, no template enforcement | Implement approval workflow, lock master templates, assign brand guardians per channel |

| Color contrast failures on accessibility audits | Brand palette not tested against WCAG AA/AAA standards | Run color_accessibility_checker.py on full palette, adjust problematic combinations |

| New hires produce off-brand content in first 30 days | Brand guidelines not included in onboarding process | Add brand guidelines review to onboarding checklist, provide quick-reference card |

Success Criteria

• Brand audit scores 4.0+/5.0 average across all seven dimensions (color, typography, logo, voice, imagery, layout, content)
• All brand color combinations meet WCAG AA contrast ratio (4.5:1 for normal text, 3:1 for large text)
• Quarterly audit variance stays below 10% across all channels
• 100% of customer-facing templates use approved brand assets
• New team members produce on-brand content within first 2 weeks of onboarding
• Zero unauthorized logo modifications detected across all channels

Scope & Limitations

In Scope: Visual identity systems (color, typography, logo, imagery), voice and tone frameworks, brand audit methodology, cross-channel application guides, co-branding rules, brand governance processes, accessibility compliance for brand colors.

Out of Scope: Brand strategy and positioning decisions (see brand-strategist skill), brand architecture models (see brand-strategist skill), marketing copy creation (see copywriting skill), design file creation (Figma, Sketch), print production specifications.

Limitations: Brand guidelines are documentation — enforcement depends on organizational process. This skill provides frameworks and audit tools but cannot enforce compliance without governance workflows. Color accessibility checking uses algorithmic WCAG formulas and does not account for all visual impairment types.
