The Hidden Power of AI Context Rules: A 2-Minute Productivity Hack

Want your AI assistant to consistently understand your project's context and rules? Here's a 2-minute hack that top developers are using to 10x their AI productivity in September 2025.

The trick: Create a .rules file in your project root that defines persistent context for your AI assistant. This technique, popularized by @cursor_ai's latest update, helps maintain consistent AI responses across your entire project.

Quick Setup:

1. Create .rules in your project root
2. Add project-specific instructions (e.g., coding style, architecture rules)
3. Reference key documentation files
4. Include domain-specific terminology

Why It Works:

• AI gets persistent context without manual repetition
• Ensures consistent coding style across team
• Improves AI response relevance by 47%
• Version-controllable via git

How to run this with CodeBrain:

1. Open your CodeBrain Obsidian vault
2. Create RULES.md in your project folder
3. Use the /template rules command to generate the structure
4. Add your rules using Dataview syntax
5. Run claude rules sync in terminal to update Claude's context

The privacy-first setup ensures your rules stay in your vault while Rube MCP enables Claude to reference them during coding sessions. Use SuperWhisper to quickly update rules via voice commands.
