Summarize your architecture rules and give your AI a persistent memory

TL;DR: When you use the /init command, you create a context file that saves you from repeating instructions in every new session.

Common Mistake ❌

You waste time copying and pasting the same project rules into every new chat.

You forgot to tell the AI about your specific test commands.

When you start a fresh session, the AI loses all previous context about your coding style or architecture.

Create your own system prompts, persist them and keep an eye on them regularly.

Problems Addressed 😔

• Repetitive and manual meta-prompting
• Inconsistent code styles across sessions
• High token usage from redundant instructions
• AI hallucinations about build or test commands
• Onboarding new projects

How to Do It 🛠️

1. Open your terminal in your project root directory.
2. Type /init if you use Claude Code or OpenCode.
3. Review the generated CLAUDE.md or AGENTS.md file.
4. Add specific "landmines" or things the AI can't see in the code.
5. Save the file, review the commit diffs, and start your next coding task.
6. You can do it again when you have new rules.

Benefits 🎯

When you initialize (/Init) your project, the AI reads all the repository immediately.

You get consistent results without extra effort.

You save tokens because you don't have to describe your stack every time.

Context 🧠

AI assistants start every session with a blank slate.

They don't remember what you told them yesterday.

Tools like Claude Code look for a specific file to understand your project.

When you provide this saved file, you close the gap between separate AI sessions.

Prompt Reference 📝

Bad Prompt:

Remember to use 2 spaces for indentation 
and always run 'npm run test:unit' 
before you finish the task.

Good Prompt:

git clone https://github.com/torvalds/linux.git

/Init

Considerations ⚠️

Keep the generated file short.

When you add too much text, the AI might get confused.

Don't include information that the AI can already find in your package.json or README.md.

Type 📝

[X] Semi-Automatic

Limitations ⚠️

You can only use this tip with AI tools that support persistent context files.

If you change your build tools, you can update the Markdown file manually, run /init again, or do both.

In Windsurf, there is no literal /init terminal command that automatically generates a configuration file, as Claude Code or OpenCode does.

Windsurf uses a more agentic approach where the AI (Cascade) either discovers your rules automatically or creates them when you ask.

Cascade, initialize a .windsurfrules file for this project. Include my tech stack, coding standards, and build commands.

• Use .cursorrules for local preferences

• Create modular AGENTS.md files for monorepos

• Keep your README.md updated for better AI indexing

Conclusion 🏁

When you use /init, you turn your AI from a temporary contributor into a permanent team member.
