# Overview

The AIOS-Agent SDK (Cerebrum) provides a structured interface between user device applications and the AIOS kernel through different functional modules.

All queries from these modules are ultimately channeled through a central `send_request(Query)` function in the AIOS-Agent SDK, which then communicates with the AIOS kernel via HTTP requests (either to localhost or a remote URL).

On the user device side, the agent contains code snippets for planning, action, memory, and storage that interact with their respective modules through the Cerebrum Client interface. This creates a clean separation between the application logic and the kernel communication layer. **Please make sure you have read about how to use and develop agents before going deep into these APIs.**&#x20;

The SDKs contain the following APIs:&#x20;

* [LLM Core API](/aios-docs/aios-agent-sdk/llm-core-api.md)
* [Memory API](/aios-docs/aios-agent-sdk/memory-api.md)
* [Storage API](/aios-docs/aios-agent-sdk/storage-api.md)
* [Tool API](/aios-docs/aios-agent-sdk/tool-api.md)

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.aios.foundation/aios-docs/aios-agent-sdk/overview.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
