What it does

Medialibrary Development is an agent skill from gdarko/laravel-vue-starter. Build and work with spatie/laravel-medialibrary features including associating files with Eloquent models, defining media collections and conversions, generating responsive images, and retrieving media URLs and paths.

Its SKILL.md is about 880 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/medialibrary-guide.md`).

It sits in Backend & APIs, covering Backend development. It works with Laravel, Vue.js, Tailwind CSS and Vite. The repository describes itself as: AI-native Laravel/Vue boilerplate. Tailwind + DaisyUI, Sanctum, Fortify, Pinia. Built-in agent skills for Claude Code, Cursor, Copilot, Gemini & Junie. The licence is MIT.

When your agent uses it

Tasks that involve Backend development

Example prompts

“/medialibrary-development”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

Identify the task (model setup, adding media, defining conversions, retrieving files, etc.).
Read references/medialibrary-guide.md and focus on the relevant section.
Apply the patterns from the reference, keeping code minimal and Laravel-native.

What it can do on your machine

Read from SKILL.md and the folder at commit 2b8eb53. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- php
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Medialibrary Development loads about 880 tokens when it runs, and up to ~4.5k if it reads all its reference files. Until then it costs about 61 tokens; SKILL.md has 254 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~61
When it runs · the whole SKILL.md, loaded when a task matches: ~880
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~4.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Media Library Development

Overview

Use spatie/laravel-medialibrary to associate files with Eloquent models. Supports image/video conversions, responsive images, multiple collections, and various storage disks.

When to Activate

Activate when working with file uploads, media attachments, or image processing in Laravel.
Activate when code references HasMedia, InteractsWithMedia, the Media model, or media collections/conversions.
Activate when the user wants to add, retrieve, convert, or manage files attached to Eloquent models.

Scope

In scope: media uploads, collections, conversions, responsive images, custom properties, file retrieval, path/URL generation.
Out of scope: general file storage without Eloquent association, non-Laravel frameworks.

Workflow

Identify the task (model setup, adding media, defining conversions, retrieving files, etc.).
Read references/medialibrary-guide.md and focus on the relevant section.
Apply the patterns from the reference, keeping code minimal and Laravel-native.

Core Concepts

Model Setup

Every model that should have media must implement HasMedia and use the InteractsWithMedia trait:

php

use Spatie\MediaLibrary\HasMedia;
use Spatie\MediaLibrary\InteractsWithMedia;

class BlogPost extends Model implements HasMedia
{
    use InteractsWithMedia;
}

Adding Media

php

$blogPost->addMedia($file)->toMediaCollection('images');
$blogPost->addMediaFromUrl($url)->toMediaCollection('images');
$blogPost->addMediaFromRequest('file')->toMediaCollection('images');

Defining Collections

php

public function registerMediaCollections(): void
{
    $this->addMediaCollection('avatar')->singleFile();
    $this->addMediaCollection('downloads')->useDisk('s3');
}

Defining Conversions

php

use Spatie\MediaLibrary\MediaCollections\Models\Media;
use Spatie\Image\Enums\Fit;

public function registerMediaConversions(?Media $media = null): void
{
    $this->addMediaConversion('thumb')
        ->fit(Fit::Contain, 300, 300)
        ->nonQueued();
}

Retrieving Media

php

$url = $model->getFirstMediaUrl('images');
$thumbUrl = $model->getFirstMediaUrl('images', 'thumb');
$allMedia = $model->getMedia('images');

Do and Don't

Do:

Always implement the HasMedia interface alongside the InteractsWithMedia trait.
Use ?Media $media = null as the parameter for registerMediaConversions().
Call ->toMediaCollection() to finalize adding media.
Use ->nonQueued() for conversions that should run synchronously.
Use ->singleFile() on collections that should only hold one file.
Use Spatie\Image\Enums\Fit enum values for fit methods.

Don't:

Don't forget to run php artisan vendor:publish --provider="Spatie\MediaLibrary\MediaLibraryServiceProvider" --tag="medialibrary-migrations" before migrating.
Don't use env() for disk configuration; use config() or set it in config/media-library.php.
Don't call addMedia() without calling toMediaCollection() — the media won't be saved.
Don't reference conversion names that aren't registered in registerMediaConversions().
