# RAG
> Enhance your agents in Devic by using RAG to retrieve external information and contextualize their responses.
**RAG (Retrieval Augmented Generation)** is the system that enables agents in **Devic** to access external information—such as documents, manuals, policies, or catalogs—and use it during execution to generate more precise and contextualized responses.
Thanks to RAG, agents can work with up-to-date or domain-specific data without relying solely on the model’s pretrained knowledge.
***
## How It Works
The platform includes a fully integrated **RAG system** that allows users to directly upload documents to enrich the model's context.
The process is **entirely automatic**:
1. The platform analyzes the uploaded documents and **splits them into sections or “chunks”** for better indexing and retrieval.
2. It generates **automatic descriptions** for each fragment, helping the agent better contextualize the information.
3. During execution, the agent decides **when and how to query** these fragments, integrating them dynamically into its operational context.
This approach removes the need for additional training or external integrations, allowing agents to work with **updated and specific knowledge** without added technical complexity.
With RAG, organizations can give their agents an extended memory that strengthens reasoning capabilities and improves precision in complex tasks.

## Configuring RAG in an Agent
To add RAG to an agent:
1. Open the agent from the Devic sidebar.
2. Scroll to the **RAG** section.
3. Select **Add document** and upload the files that will form part of the knowledge base.
Supported formats include:
* `.pdf`
* `.docx`
* `.txt`
* `.csv`
Each file is processed automatically and displayed in the agent interface with its name and status.

## Document Preview and Summary
After uploading a document, you can view its details from the right-hand side panel.\
Devic displays **metadata** and an **automatic summary** of the content.
| Field | Description |
| ---------------------- | ---------------------------------------------------------------------- |
| **Name** | Name of the uploaded file. |
| **Size** | File size. |
| **Created / Modified** | Creation and last modification dates. |
| **Summary** | Summary of the content, automatically injected into the agent context. |
The **Summary** field can be manually edited to refine the document description.\
This allows prioritizing the most relevant information and optimizing agent queries.
***
## Best Practices
* Upload only the documents necessary for the agent's context.
* Avoid overly long files or irrelevant content.
* Update summaries when document content changes.
* Use descriptive names to improve identification.
* Review the document set periodically to ensure it remains up to date.

## Use Cases
| Agent Type | RAG Application |
| ------------- | ---------------------------------------------------------- |
| **Legal** | Consults contracts or legal texts stored in PDFs. |
| **Sales** | Looks up data in catalogs, product sheets, or price lists. |
| **Technical** | Retrieves content from manuals or internal guides. |
| **Support** | Accesses knowledge bases or customer documentation. |
