# Asset Criteria

All assets should meet the specified criteria when contributing to the project, and maintainers will refer back to this when reviewing GitHub PRs ~~and direct art submissions in Discord~~.

General assets are categorized by 2 types in our project as you should know from our [file organization](/dev-guide/readme/file-naming-and-organization/file-organization.md). These two types, internal and external, have different criteria based on their nature.

*The sub pages contained under this one will be split based on these 2 types, but we will also be adding a 3rd page to represent the importing criteria of external assets.*

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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, and the optional `goal` query parameter:

```
GET https://ss3d.gitbook.io/dev-guide/guidelines/asset-criteria.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
