Modular Prompting Rules That Actually Work
TL;DR:
- Rules modules control consistency and tone across all your AI outputs
- Banned phrases prevent robotic-sounding content while style requirements maintain readability
- Writing conventions simplify complex structures that confuse readers
- Regular updates keep your rules relevant as your content strategy evolves
- Custom rules and team sharing features help maintain brand voice across projects
The Rules module sits at the heart of effective AI prompt writing. Think of it as your quality control system that ensures every piece of content sounds like it came from the same human writer, not a rotating cast of robots.
What Rules Modules Actually Do
Rules modules work by setting boundaries and guidelines before your AI starts writing. They operate on three main levels:
Banned phrases stop your AI from using overused marketing speak or awkward constructions. Instead of letting it write "unlock the secrets of content marketing," your rules can block this and push for clearer alternatives.
Style requirements handle the mechanical side of writing. This covers sentence variety, punctuation limits, and readability targets. You might set a reading age of 12 or ban semicolons entirely.
Writing conventions tackle structural issues. They convert clunky phrases like "not only does this help with X, but it also improves Y" into simpler, more direct language.
Why Consistency Matters More Than You Think
Without consistent rules, your AI outputs will sound like different people wrote them. One piece might be conversational and punchy while another reads like a corporate manual.
This inconsistency confuses your audience. They can't lock onto your voice or predict what to expect from your content. It also makes your brand seem scattered and unprofessional.
Rules modules solve this by applying the same standards to every piece of content. Your blog posts, social media updates, and email campaigns all speak with the same voice and follow the same quality standards.
Setting Up Rules That Work
Start with your biggest pain points. If your AI keeps producing marketing fluff, create banned phrase lists. If readability is inconsistent, set style requirements first.
Begin with banned phrases. List the words and structures that make content sound generic. Common culprits include "cutting-edge," "revolutionary," and "best-in-class." Also ban awkward structures like "let's dive deep into" or "in today's digital landscape."
Set clear style boundaries. Decide on your preferred sentence length range, punctuation rules, and complexity level. If you're writing for a general audience, cap your reading age and avoid industry jargon.
Define your writing conventions. Create rules for how you handle comparisons, lists, and transitions. Simple, direct language usually works better than complex academic structures.
Customising Rules for Your Brand
Generic rules won't capture your specific brand voice. You need to customise based on your audience, industry, and communication style.
Technical audiences might handle more complex language and industry terms. Consumer brands often need simpler, more emotional language. B2B companies might sit somewhere in the middle.
Test your rules by running the same prompt with different rule sets. Compare the outputs and see which version sounds most like your brand. Adjust based on what you find.
Many platforms now offer rule sharing between team members. Use this to maintain consistency across multiple writers and projects. Everyone works from the same playbook.
Common Rules Module Mistakes
The biggest mistake is making rules too restrictive. If you ban every possible problem phrase, your AI has nothing left to work with. Focus on the worst offenders first.
Another common issue is forgetting to update rules as your brand evolves. What worked six months ago might not match your current communication style. Review and adjust quarterly.
Don't ignore the human element either. Rules modules help with consistency, but they can't replace editorial judgment. Always review outputs before publishing.
FAQs
Can I create completely custom rules or am I stuck with presets?
Most modern AI platforms let you create custom banned phrase lists and style requirements. Some offer template starting points that you can modify. Check your platform's documentation for specific customisation options.
How do I know if my rules are too strict?
If your AI outputs start sounding repetitive or struggle to meet word counts, your rules might be too restrictive. Try loosening banned phrase lists or style requirements and test the results.
Should I use different rule sets for different content types?
Yes, blog posts might need different rules than social media updates or technical documentation. Many platforms let you save multiple rule sets and switch between them as needed.
How often should I review and update my rules?
Review your rules every quarter or whenever you notice consistency issues in your outputs. Major brand voice changes or new content types might require immediate rule updates.

Wrap-up
Rules modules turn inconsistent AI outputs into branded content that sounds human and professional. The key is finding the right balance between control and flexibility.
Start with your biggest consistency problems and build rules gradually. Test different approaches and adjust based on results. Remember that rules are tools to improve your content, not chains that restrict creativity.
Regular reviews keep your rules relevant as your brand and content strategy evolve. With properly configured rules, your AI becomes a reliable team member that consistently delivers on-brand content.
