What is backend-laravel?

A guide for building and maintaining Laravel applications, including APIs and websites. Laravel is a PHP framework that provides common tools for routes, databases, authentication, queues, and email.

Use it for Laravel routes, controllers, form validation, database models and migrations, authentication, queues, notifications, mail, testing, and query debugging.

It gives a consistent way to structure controllers, validation, models, migrations, and business logic. This reduces mistakes when changing server-side application code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00019	$0.00758
Opus 5.5	$0.00008	$0.00303
Sonnet 5.5	$0.00004	$0.00152
Haiku 4.5	$0.00002	$0.00076

Security

Grade A, and why

backend-laravel scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/dev-check.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Backend - Laravel

When to use this skill

Creating APIs, controllers, routes, form requests, models, and migrations.
Implementing authentication/authorization, validation, queues, notifications, or mail.
Debugging performance, database queries, or request/response handling.

Quick start

Install PHP deps: composer install.
Env: copy .env.example -> .env; set APP_KEY via php artisan key:generate; configure DB and queue.
Run migrations/seeders: php artisan migrate --seed (if seeders exist).
Serve: php artisan serve or via Sail/Valet; tests: php artisan test; quality: composer lint if defined.

Project structure basics

Routes: routes/api.php for stateless APIs; routes/web.php for web routes with sessions.
Controllers: thin; push business logic into services/actions; type-hint dependencies for auto DI.
Form Requests: validate/authorize input; keep controllers lean.
Models and Eloquent: define fillable/guarded; relationships and scopes for query reuse.
Migrations/Seeders: keep schema in migrations; seed minimal fixtures for dev/test.

Coding principles

Keep controllers thin; validate/authorize via Form Requests; push logic to services/actions.
Normalize errors in exception handler; avoid leaking internals; include request IDs in logs.
Secure by default: policies/gates for authz, hashed secrets, avoid logging sensitive data.
Handle migrations carefully; prefer reversible changes and minimal seeds for tests.
Enforce tests and available lint/static tools before merge (run scripts/dev-check.sh).

Patterns and snippets

API route, Form Request, controller, queue, and caching templates live in references/snippets.md.
Use resources/transformers to keep API shapes consistent; eager-load to avoid N+1.

Security and auth

Use Laravel Sanctum/Passport for API auth; hash secrets; never log credentials.
Authorize actions via policies or gates; ensure middleware protects routes.

Error handling and logging

Customize exception rendering in app/Exceptions/Handler.php; map validation and domain errors clearly.
Use structured logs; include request IDs for tracing.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
