## How to Use Indexes

This table is organized by project and product naming in local source code, and is not a guarantee that all versions have been released. Check the package content and target framework of the target version when installing; new capabilities in the source code master branch may not have entered the package version you are using.

The same package may carry multiple plugin variants, and Web, daemon, and gateway may also be divided into independent projects. The dependency relationship is based on the target version of `.plugin`, `.deploy` and the project file. The loading order cannot be inferred just by the package name prefix.

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.zongsoft.com/documentation/en/references/packages.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
