FAQ
After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.
Example:
Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.

Some PHP packages are not free to download and because of that hosted in private repositories.
In this case some credentials are needed to access such packages.
Please use the auth.json textarea to insert credentials, if a package is coming from a private repository.

- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Laravel Prism Prompt
Laravel Mailable-like API for LLM prompts with Prism.
Define your prompts as YAML templates + PHP classes. Move text and model settings out of code, separate the system message from the user message, parse responses into typed DTOs, and observe every call via events with USD cost attached — the same way you'd compose a Mailable.
That's the whole loop. Everything else in this package is a layer on top: DTO mapping, multi-provider fallback, prompt-injection defence, parallel execution with prompt caching, observability, durable operations.

Settings priority
Settings resolve highest-wins:
- Class property (e.g.
protected ?float $temperature = 0.5) - YAML field
- Config default (
config('prism-prompt.default_*'))
Subclassing
Use Prompt::load() for the simplest case. When you need typed DTOs,
custom message construction, or fluent variables in __construct,
subclass:
Structured output (recommended for new code, since v0.15.0)
For prompts whose output must conform to a fixed shape, declare a Prism schema
via getJsonSchema(). The base will route the call through
Prism::structured() and pass the decoded array straight to
parseStructured() — no extractJson() regex, no YAML JSON example to drift
out of sync.
getJsonSchema() returning null (the default) keeps the legacy
Prism::text() + extractJson() path, so existing subclasses continue to work
unchanged. See docs/structured-output.md for the
full contract (event payload, fakes, error handling).
YAML lookup (in priority order):
$promptNameproperty — relative path fromprompts_path- Naming convention —
GreetingPrompt→greeting.yaml $promptsDirectory— group prompts under a subdirectory
getTemplatePath() is overridable for full control.
