Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00010 | $0.00379 |
| Sonnet 5 | $0.00004 | $0.00152 |
| Haiku 4.5 | $0.00002 | $0.00076 |
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 11d ago.
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; setAPP_KEYviaphp artisan key:generate; configure DB and queue. - Run migrations/seeders:
php artisan migrate --seed(if seeders exist). - Serve:
php artisan serveor via Sail/Valet; tests:php artisan test; quality:composer lintif defined.
Project structure basics
- Routes:
routes/api.phpfor stateless APIs;routes/web.phpfor 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.
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

backend-laravel is a skill published in the GitHub repository kieutrongthien/skills-fullstack (2 stars, last pushed 7mo ago), licensed MIT. It adds 19 tokens to every session and 758 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
