How to Build a Brand Bible for Your AI Agents
Why Your AI Agents Need a Brand Bible
If your AI outputs feel random, inconsistent, or “off,” it’s not just the model. It’s the inputs.
AI is like a very fast, very literal junior creator. If you don’t give it clear rules, it will guess. Sometimes it guesses well. Most of the time, it doesn’t.
A brand bible fixes that.
A good brand bible tells your AI agents:
- How you sound
- Who you’re talking to
- What you will and won’t say
- What you care about most
- How your content should feel on every platform
When you put this into a clear system and plug it into a platform like ShortsFire, your agents stop guessing and start creating content that actually feels like your brand.
You’re not just “using AI.” You’re building a repeatable content machine.
Let’s break down how to do it step by step.
Step 1: Define Your Brand Core
Your brand core sits at the top of your bible. It guides every AI decision.
Capture this in a short, clear section your agents can reference quickly.
1.1 Brand One-Liner
Write one sentence that explains your brand in plain language.
Template:
We help [specific audience] get [specific result] through [how you do it] with a [tone or style] approach.
Example:
We help busy solo creators grow with short-form content using simple, repeatable frameworks and a no-fluff teaching style.
1.2 Audience Snapshot
AI needs to know who it’s talking to.
Include:
- Who they are: role, stage, niche
- What they want
- What they struggle with
- What they care about
Example:
Audience: Solo creators and founders who want to grow on YouTube Shorts, TikTok, and Reels.
Goals: More views, more followers, and content that feels like “them” without burning out.
Struggles: Inconsistent posting, idea paralysis, fear of being cringe.
They care about: Practical tips, clear examples, and systems that save time.
Keep this tight. Your AI agents don’t need a novel. They need clarity.
Step 2: Lock In Your Brand Voice
This is where most people stay vague.
“Friendly, helpful, authentic” is not a voice. AI can’t work with that.
You want your voice broken into specific, repeatable rules.
2.1 Tone
Answer these three questions in 1 to 2 sentences each.
-
How do you talk?
- Casual or formal?
- Playful or serious?
- Direct or more gentle?
-
How do you explain things?
- Short and punchy or detailed and deep?
- More examples or more theory?
-
How do you motivate people?
- Tough love or supportive coach?
- Data focused or story focused?
Example tone section:
- Tone is conversational, direct, and supportive.
- No hype, no empty motivation. Advice should be practical and specific.
- Use simple, clear language. Avoid jargon unless it’s common creator language.
2.2 Voice Rules
Turn your style into rules the AI can actually follow.
Include:
- What you do want
- What you don’t want
Example:
Do:
- Use contractions: you’re, it’s, don’t
- Speak to one person: “you,” not “you guys”
- Use simple, everyday words
- Give clear next steps and examples
- Vary sentence length
Don’t:
- Don’t write like a corporate press release
- Don’t over-explain obvious points
- Don’t add fake urgency or hype
- Don’t use emojis unless specifically requested
You can paste these rules directly into your ShortsFire agent settings so every script, caption, and hook follows the same style.
Step 3: Create Your Messaging Pillars
Your AI agents should not talk about everything. They should talk about the same core themes over and over in different ways.
Those themes are your messaging pillars.
Aim for 3 to 5 pillars.
Examples for a content creation brand:
- Short-form content strategy
- Hook and storytelling frameworks
- AI workflows and content systems
- Creator mindset and consistency
- Monetization from short-form content
For each pillar, write:
- A 1 sentence description
- 3 to 5 example topics
Example:
Pillar: AI workflows and content systems
Help creators use AI and tools to create more content in less time without losing their voice.
Example topics:
- How to brief AI agents so they sound like you
- Turning long-form content into a month of Shorts
- Building a repeatable content pipeline inside ShortsFire
- Prompt templates that actually save time
- What to never outsource to AI
These pillars guide your AI when you ask for:
- Content ideas
- Hooks
- Scripts
- Carousels or threads
- Email angles
Instead of random output, you get content that reinforces your core message.
Step 4: Style & Formatting Rules
Your brand bible should also cover how your content looks and flows, especially for short-form scripts.
Break this into three parts.
4.1 General Writing Rules
Spell out the basics.
Examples:
- Use short paragraphs, 1 to 3 lines each
- Avoid long, complex sentences
- Use bullet points for lists
- Prefer active voice over passive voice
- Explain jargon in simple words
4.2 Platform-Specific Rules
Shorts, Reels, TikTok, YouTube descriptions, and emails each have their own rhythm. Help your AI agents adapt.
Short-form video scripts:
- Start with a hook in the first 1 to 2 seconds
- Get to the point fast, no long intros
- Aim for 3 to 5 clear beats or points
- End with a clear call to action
Captions:
- First line should stop the scroll
- Use short, skimmable lines
- Include 1 clear CTA (comment, follow, save, click link)
YouTube descriptions:
- 1 to 2 sentence summary at the top
- Add timestamps if relevant
- Include main links in the first 2 lines
You can store these rules inside your ShortsFire templates so every agent knows how to structure content for each platform.
4.3 Visual & On-Screen Cues
Even text-based AI agents can help you plan visuals if you teach them your style.
Include:
- Preferred subtitle style (all caps or sentence case)
- On-screen text rules (short, bold, easy to read)
- B-roll or cutaway preferences
- Camera style (talking head, screen share, selfie, etc.)
Example prompt rule:
When writing scripts, suggest on-screen text in brackets like [ON SCREEN: 3 Hooks in 15 Seconds] and simple b-roll ideas.
Step 5: Do & Don’t Examples
AI learns fast from examples. So do humans.
Add a small “do vs don’t” section for:
- Hooks
- Scripts
- Captions
Hook Examples
Don’t:
In this video, I’m going to tell you about how to grow on social media.
Do:
If your Reels keep flopping, you’re probably making this one hook mistake.
Stop asking “What should I post?” and start using this 3-word content formula.
Caption Examples
Don’t:
Social media is very important for brands and creators these days. You have to post consistently and connect with your audience.
Do:
Your content isn’t boring.
Your format is.Try this:
- Start with a bold statement
- Show 1 quick example
- End with a simple action
Save this for your next video.
Add 3 to 5 examples in each category. Label them clearly so your AI agents can see the pattern.
Step 6: Turn Your Brand Bible Into AI Instructions
A brand bible is only useful if your AI can actually use it.
Here’s how to plug it into your workflow.
6.1 Create a Master System Prompt
Turn your bible into a single, reusable instruction block.
Structure it like this:
- Who you are as a brand
- Who you speak to
- Voice and tone rules
- Style and formatting rules
- Content pillars
- Do / Don’t examples
You can store this inside your ShortsFire workspace as your “Brand System Prompt” and reference it in every agent or template.
6.2 Build Specialized Agents
Instead of one generic AI assistant, create separate agents for:
- Hook generation
- Short-form scripts
- Caption writing
- Idea generation
- Repurposing long-form content
Each agent:
- Inherits the same Brand System Prompt
- Adds extra rules for its specific job
Example for a Short-Form Script Agent:
- Always open with a strong hook
- Keep scripts between 20 and 45 seconds
- Use simple, spoken language
- Add subtle CTAs to follow or save
Step 7: Keep It Alive, Not Static
Your brand bible isn’t a PDF you finish once and forget. It should evolve as your content and audience evolve.
Make it a habit to:
- Review performance: What hooks and scripts are working best?
- Save winners: Add high performing scripts and hooks as new “Do” examples
- Trim the fluff: Remove rules you don’t actually follow
- Tighten clarity: Rewrite any vague or confusing parts
If a piece of AI content “sounds wrong,” don’t just fix the output. Update the brand bible so it doesn’t happen again.
Over time, this turns your AI agents into something that feels less like a generic model and more like a trained member of your content team.
Final Thoughts
AI isn’t the threat to your brand voice. Vagueness is.
When you build a clear brand bible and plug it into your ShortsFire workflows, your agents stop producing generic scripts and start creating content that:
- Sounds like you
- Stays on message
- Scales across platforms
You’re not just asking AI to “write a caption.”
You’re giving it a proven system to follow.
Start simple:
- One brand one-liner
- One audience snapshot
- A handful of voice rules
- Three messaging pillars
- A few “do vs don’t” examples
Then refine as you go.
Your future content machine will thank you.
