OI Laravel AI Add-on

The AI backend for your Laravel application. It maintains a provider/model catalog with pricing, records the token usage of every agent call, reports cost per project / agent / model, and centralizes your agents' system prompts.

Features

• Provider & model catalog — AiProvider / AiModel tables with per-1M-token input/output pricing, seeded from a JSON registry shipped with the package.
• Automatic usage tracking — a listener records every Laravel\Ai\Events\AgentPrompted event into ai_requests (tokens, model, provider, project), with zero host code.
• Cost reporting — AiUsageReporter aggregates usage into per-project, per-agent, and per-model cost summaries over any period.
• Prompt registry — AiPromptVariableRegistry is the single source of truth for agent system prompts, with :variable placeholder compilation (mirrors mail templating).
• Self-updating tariffs — php artisan ai:update-registry fetches a fresh catalog and pricing from a remote URL and persists it locally.
• Host-agnostic — resolves the host's Project / AgentRun models through config and persists settings through a SettingStore contract.

Requirements

• PHP 8.2+
• Laravel 12 or 13
• laravel/ai 0.7+

Installation

composer require oi-lab/oi-laravel-ai

The package auto-discovers and registers itself via Laravel's service provider mechanism.

Assisted installation (recommended)

Run the interactive installer and answer the prompts — it publishes the config, captures the host models / setting store / registry into your .env, runs the migrations, and seeds the catalog. Every step is confirmed, so it is safe to re-run:

php artisan ai:install

Manual installation

php artisan vendor:publish --tag=oi-laravel-ai-config
php artisan vendor:publish --tag=oi-laravel-ai-migrations
php artisan migrate

The ai_requests table has nullable foreign keys to your projects and agent_runs tables (UUID keys). Make sure those tables exist before migrating, or adjust the published migration to match your schema.

Configuration

config/oi-laravel-ai.php:

All keys read from environment variables (OI_AI_PROJECT_MODEL, OI_AI_SETTING_STORE, OI_AI_REGISTRY_PATH, OI_AI_REGISTRY_URL, …).

Usage

Catalog

use OiLab\OiLaravelAi\Support\AiCatalog;

$registry = AiCatalog::read();   // bundled asset or host-configured path
$counts = AiCatalog::sync($registry); // upserts providers + models
// ['providers' => 5, 'models' => 15]

Seed the catalog (and, when a SettingStore is bound, the default models + prompts) from your DatabaseSeeder:

$this->call(\OiLab\OiLaravelAi\Database\Seeders\AiCatalogSeeder::class);

Usage tracking

Tracking is automatic. Once the package is installed, every agent prompt dispatched through laravel/ai is recorded:

use OiLab\OiLaravelAi\Models\AiRequest;

AiRequest::query()->where('prompt_type', 'DocWriterAgent')->count();

Cost reporting

use OiLab\OiLaravelAi\Services\AiUsageReporter;

$summary = app(AiUsageReporter::class)->summaryForProjects(
    projectIds: [$project->id],
    start: now()->startOfMonth(),
    end: now()->endOfMonth(),
);

$summary->estimated_cost_usd; // float, rounded to 4 decimals
$summary->by_agent_type;      // [['prompt_type' => ..., 'count' => ..., ...], ...]
$summary->by_model;           // [['model_name' => ..., 'count' => ..., ...], ...]

Prompt registry

use OiLab\OiLaravelAi\Support\AiPromptVariableRegistry;

$prompt = AiPromptVariableRegistry::compile(
    AiPromptVariableRegistry::defaultPrompt(AiPromptVariableRegistry::DOC_WRITER),
    ['project_name' => 'Acme', 'language' => 'français'],
);

The app_name global is injected automatically. Use AiPromptVariableRegistry::keys(), label(), and variablesFor() to build a settings UI.

Commands

# Assisted, interactive installation (publish, configure, migrate, seed).
php artisan ai:install [--force]

# Refresh the catalog + pricing from the configured remote registry URL.
php artisan ai:update-registry [--url=https://…] [--no-write]

Customizing host models

The package never hardcodes your domain models. Override the bindings in config so AiRequest belongs to your own Project / AgentRun:

'models' => [
    'project' => \App\Models\Project::class,
    'agent_run' => \App\Models\AgentRun::class,
],

Settings (default models, prompt overrides) are persisted through the SettingStore contract. Install the recommended oi-lab/oi-laravel-settings (listed under suggest) and its adapter is wired automatically. To use your own storage, implement OiLab\OiLaravelAi\Contracts\SettingStore and point setting_store at it.

Testing

composer test

AI Assistant Skills

This package ships a skill that teaches AI coding assistants (Claude Code, JetBrains AI) how to use it. The recommended way to install it is the unified oi:skills command from oi-lab/oi-laravel-development:

php artisan oi:skills oilab-laravel-ai --project

A deprecated package-local fallback is available for projects that don't use oi-lab/oi-laravel-development:

php artisan oi-ai:install-ai-skill

See docs/advanced/skills.md for details.

Documentation

The docs/ folder is importable into any app using oi-lab/oi-laravel-documentation:

php artisan doc:import
