php-developer

A set of coding guidance for modern PHP applications, especially those built with Laravel or Symfony. It covers PHP structure, database access, APIs, authentication, queues, testing, static analysis, and formatting.

In plain words
What is it for?
Use it when writing PHP 8.x code, Laravel applications, Symfony applications, Eloquent database code, queues, APIs, PHPUnit or Pest tests, or PHPStan checks.
Why use it?
PHP projects benefit from consistent ways to organise application logic, validate requests, access data, and protect APIs. This guidance gives the agent concrete conventions for those tasks.

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.

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.

Security

Grade A, and why

php-developer 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 yesterday.

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.

Dependency Injection — Service Provider

// app/Providers/AppServiceProvider.php
public function register(): void
{
    $this->app->bind(EmailSenderInterface::class, function () {
        return match(config('mail.default_provider')) {
            'resend'   => new ResendEmailSender(config('services.resend.key')),
            'sendgrid' => new SendGridEmailSender(config('services.sendgrid.key')),
            default    => throw new InvalidArgumentException("Unknown email provider"),
        };
    });
    
    $this->app->bind(UserRepository::class, EloquentUserRepository::class);
}

What ships with it

1 file 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.

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.

php-developer is a skill published in the GitHub repository mtnyilmaz/agents (6 stars, last pushed 3mo ago), licensed MIT. It adds 50 tokens to every session and 1,421 once invoked, about $0.0003 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.
