@Mention

Add context to AI conversations to help AI understand your needs and generate code that follows your project standards. You can add code files, project folders, local attachments, and project rules.

Ways to add context

Method	Action	Description
Click button	Click the context selector button @ in the lower-right corner of the input box	Opens the selector window to browse all context types
Type @	Type @ and continue typing	Searches files, folders, and rules in real time with highlighted matches
Drag or paste	Drag files or images to the chat box	Supports md, xmind, xlsx, docx, pdf, jpg, png

Context types

Type	Purpose	Common scenarios
@file	Reference code files or rule files	Query implementations, refactor code, understand modules
@folder	Reference entire directories	Refactor module structure, generate tests, cross-file queries
@attachments	Reference local files or images	Generate code from mockups, analyze documents, process spreadsheets
@rule	Reference project rules	Generate code following team styles, enforce standards

@file

Reference code files in your project. Supports querying and modification.

How to add

• Type @file and enter the file name to search
• Drag files from the file explorer to the chat box

Rule files (such as files in the .qoder/rules directory) can also be found via @file search.

@folder

Reference entire directories. Useful when you need to understand or modify a group of related files.

How to add

Type @folder and enter the directory name to search

@attachments

Reference local files or images to let AI analyze document content, generate code from designs, or process spreadsheet data.

Supported file types

Type	Formats	Scenarios
Images	jpg, png	Generate frontend code, analyze layouts, extract text
Documents	md, pdf, docx	Analyze content, extract information, generate comments
Spreadsheets	xlsx	Analyze data structures, generate processing code
Mind maps	xmind	Understand architecture, generate code frameworks

How to add

• Type @attachments to select local files
• Drag or paste files directly to the chat box
• Images are displayed separately at the top of the input box with preview support

@rule

Reference project rules to make AI follow specific coding styles, framework conventions, or business standards.

Rules are embedded in every model call as persistent, reusable context. They’re ideal for defining coding styles, naming conventions, and framework usage patterns that need to stay consistent across your entire project.

How to add

• Type @rule to select configured rules
• When the rule list is empty, create new rules directly via the quick entry without going to the settings page

Rule files (such as .md files in the .qoder/rules directory) can be referenced as @rule (persistent context) or found via @file search (regular file).

Add to Chat

Files (including code files and Spec files) support fine-grained selection for adding context. You can select any content snippet in a file and add it to the current conversation by:

• Clicking Add to Chat in the floating menu
• Using the shortcut Command+L (macOS) / Ctrl+L (Windows/Linux)

The selected content will be attached as context to the input box, helping the agent understand your intent more precisely.

You can also add content from the conversation flow into the current chat — select a reply or reference a segment in the conversation flow and use Add to Chat to attach it to the input box, making it easy to build on earlier context in the same conversation and cut down on retyping.

Best practices

Combine context types

Combine different context types in one prompt:

@src/api.js @tests/api.test.js @rule coding-style
Add test cases for this API module and ensure they follow team coding standards

Leverage recommendations

After typing @, Qoder displays commonly used files at the top of the list:

• Current file: The file you’re editing
• Recently opened: The 2 most recently accessed files

Click recommended files to add them quickly without searching.

Use instant search

After typing @ and continuing to type, Qoder searches matching files, folders, and rules in real time with highlighted matching characters.
