Context Mentions

Context mentions let you reference specific files, folders, or your entire project when talking to OneMillion Code. This helps it understand exactly what you're working with.

What Are Context Mentions?​

When you type @ in the chat, OneMillion Code can reference:

  • Files — @src/App.tsx
  • Folders — @components/
  • Workspace — @workspace

This gives OneMillion Code direct access to your code without you having to copy-paste it.

How to Use @ Mentions​

Basic Usage​

  1. Type @ in your message
  2. Start typing a file or folder name
  3. Select from the autocomplete suggestions
  4. Press Enter or Tab to confirm

Examples​

Reference a specific file:

Can you explain what @src/App.tsx does?

Reference a folder:

Look at all the components in @components/ and tell me what each does.

Reference the whole project:

@workspace What's the overall structure of this project?

Types of Mentions​

@file​

Reference a specific file:

@src/components/Button.tsx has a bug. The onClick isn't firing.

OneMillion Code will read the file and understand its contents.

@folder​

Reference all files in a folder:

@src/pages/ - which of these pages handles user authentication?

OneMillion Code will scan the folder contents.

@workspace​

Reference your entire project:

@workspace Where is the database connection configured?

Useful for searching across your codebase.

When to Use Context Mentions​

Discussing Code​

I want to add a new prop to @components/Card.tsx. 
Can you show me how?

Debugging​

@src/utils/api.ts is throwing an error on line 42. 
Here's the error: [error message]

Understanding Existing Code​

@src/hooks/ - explain what each custom hook does.

Making Changes​

Update @src/styles/theme.ts to use a darker color palette.

Finding Things​

@workspace Where do we handle form validation?

Context Mention Tips​

Be Specific​

The more specific your mention, the better OneMillion Code can help:

  • ✅ @src/components/Header.tsx
  • ⚠️ @src/ (very broad)
  • ❌ "that file" (no context)

Combine with Questions​

@src/App.tsx - why are we using useEffect here? 
I don't understand line 15.

Multiple Mentions​

You can use multiple mentions in one message:

I want @components/Button.tsx to have the same styling as @components/Card.tsx

With Code​

Combine mentions with code snippets:

In @src/utils/helpers.ts, can you change this:
```javascript
export const formatDate = (date) => date.toString();

to use proper date formatting?


## What OneMillion Code Sees

When you use a context mention, OneMillion Code:

1. Reads the file or folder contents
2. Understands the code structure
3. Uses that context to answer your question
4. Can propose changes to those specific files

It's like showing OneMillion Code your screen and pointing at something.

## Common Questions

### Q: Do I need to save files before mentioning them?
**A:** Yes, OneMillion Code reads the saved version of files.

### Q: Can I mention files outside my project?
**A:** No, mentions are limited to your current workspace for security.

### Q: What if the file doesn't exist?
**A:** OneMillion Code will let you know it can't find the file. Check the path.

### Q: Is there a limit to how much I can mention?
**A:** Mentioning very large folders or many files at once may hit context limits. Be specific when possible.
