Memory Bank: Your AI's Persistent Memory (now with Clean Code)

A comprehensive, framework-agnostic project documentation template system that creates a structured "memory bank" for your projects. Designed to improve collaboration between developers and AI assistants by maintaining a persistent knowledge base.

📋 Overview

Memory Bank provides a structured approach to documenting all aspects of a project, ensuring that information is accessible, maintainable, and useful for both human developers and AI assistants. When used properly, these files create a persistent knowledge base that improves collaboration and maintains continuity across development sessions.

Usage Pattern

1. Create a fresh context with the AI Assistant

2. prompt: review all files in the memory-bank directory. Let's work on the kanban task: [copy text from 07-kanban.md]

3. After task is complete, reviewed and tested, to the AI Assistant: update the appropriate memory-bank files for the work just completed. This must be part of your routine. The AI Assistants (at least in 2025) won't consistently update the memory-bank automatically. Giving the Assistant this direct prompt yields in high quality memory-bank updates.

4. git add / commit / push

5. Important: Start a fresh context for the next task. This prevents bloated contexts and reduces the tendancy for the AI Assistant to drift and hallunicate.

Code review what is generated. Always.

How to Use These Templates

1. Copy the entire memory-bank directory to your new project's root
2. Systematically go through each file (starting with 00-index.md) and replace the placeholder content with information specific to your project
3. Update the "Last Updated" date whenever you make significant changes to a file

🤖 Using AI Assistants to Populate Memory-Bank Files

AI coding assistants can help you efficiently populate your memory-bank files. Below are example prompts to help customize these templates for your specific project.

General Project Setup

"I've set up a new [project type] using [technologies]. Can you help me populate my memory-bank files with relevant information based on the project structure and technologies? I already have the templates in place in the memory-bank directory."

Technology-Specific Examples

For a Next.js Project

"I'm working on a Next.js project with a PostgreSQL database and Prisma ORM. Can you help me fill out the following memory-bank files based on this tech stack:
1. 02-techContext.md - Include Next.js, React, PostgreSQL, and Prisma details
2. 03-systemPatterns.md - Include common Next.js patterns and architecture
3. 04-database.md - Include Prisma model definitions and relationships
4. 09-environment.md - Include typical Next.js environment setup"

For a Django Project

"I've created a Django project with a PostgreSQL database. Please help me populate these memory-bank files:
1. 02-techContext.md - Include Django, Python, and PostgreSQL details
2. 03-systemPatterns.md - Include Django MVT architecture patterns
3. 04-database.md - Help me document my Django models
4. 13-quick-reference.md - Include common Django management commands"

For a Mobile App Project

"I'm developing a React Native mobile app with Firebase backend. Please help me populate these memory-bank files:
1. 02-techContext.md - Include React Native and Firebase details
2. 03-systemPatterns.md - Include mobile app architecture patterns
3. 09-environment.md - Include mobile development environment setup
4. 10-ai-interaction-guidelines.md - Help me set guidelines for mobile app development with AI"

File-Specific Prompts

For Product Vision (01-product-vision.md)

"Based on this project idea: [brief project description], help me populate the product-vision.md file with a compelling problem statement, solution approach, and key features."

For Technical Context (02-techContext.md)

"My project uses these technologies: [list technologies and versions]. Help me populate the techContext.md file with relevant information, including setup instructions and resource links."

For Database Documentation (04-database.md)

"Based on these database models [describe models or share code], help me populate the database.md file with proper documentation of fields, relationships, and query patterns."

For UI Design (05-uidesign.md)

"My application has these main screens: [list key screens]. Help me document the UI components and design principles in the uidesign.md file."

For Code Snippets (11-code-snippets.md)

"Based on my project's code, help me identify and document common patterns and helper functions for the code-snippets.md file."

Using AI to Update Memory-Bank Files

"I've made significant changes to my project, including [describe changes]. Help me update the following memory-bank files to reflect these changes: [list files]."

Analyzing Existing Project for Memory-Bank Population

"I have an existing [project type] with [technologies]. I've just added memory-bank templates. Can you analyze my project structure and help me populate these templates based on what you can infer about my project?"
