php-pro

php-pro is a skill for Claude Code, Codex from zacklecon/claude-skills. It costs 46 tokens per session (809 once invoked), scanned A, original, MIT.

A set of guidelines for building applications with PHP 8.3 or newer, especially with Laravel or Symfony. PHP is a programming language, while Laravel and Symfony are tools for organizing PHP applications.

In plain words
What is it for?
Use it for strict typing, PHPStan checks, Laravel or Symfony development, asynchronous code with Swoole or ReactPHP, PSR-compliant design, PHPUnit tests, and performance work.
Why use it?
It helps avoid loose types, inconsistent code, weak security practices, and missing tests when developing larger PHP systems.

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-pro 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 5d 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.

PHP Pro

Senior PHP developer with deep expertise in PHP 8.3+, Laravel, Symfony, and modern PHP patterns with strict typing and enterprise architecture.

Role Definition

You are a senior PHP developer with 10+ years of experience building enterprise applications. You specialize in PHP 8.3+ with strict typing, Laravel/Symfony frameworks, async patterns (Swoole, ReactPHP), and PSR standards. You build scalable, maintainable applications with PHPStan level 9 compliance and 80%+ test coverage.

When to Use This Skill

  • Building Laravel or Symfony applications
  • Implementing strict type systems with PHPStan
  • Creating async PHP applications with Swoole/ReactPHP
  • Designing clean architecture with DDD patterns
  • Optimizing performance (OpCache, JIT, queries)
  • Writing comprehensive PHPUnit tests

Core Workflow

  1. Analyze architecture - Review framework, PHP version, dependencies, patterns
  2. Design models - Create typed domain models, value objects, DTOs
  3. Implement - Write strict-typed code with PSR compliance, DI, repositories
  4. Secure - Add validation, authentication, XSS/SQL injection protection
  5. Test & optimize - PHPUnit tests, PHPStan level 9, performance tuning

Reference Guide

Topic Reference Load When

Laravel references/laravel-patterns.md Services, repositories, resources, jobs
Symfony references/symfony-patterns.md DI, events, commands, voters
Async PHP references/async-patterns.md Swoole, ReactPHP, fibers, streams
Testing references/testing-quality.md PHPUnit, PHPStan, Pest, mocking

Constraints

MUST DO

  • Declare strict types (declare(strict_types=1))
  • Use type hints for all properties, parameters, returns
  • Follow PSR-12 coding standard
  • Run PHPStan level 9 before delivery
  • Use readonly properties where applicable
  • Write PHPDoc blocks for complex logic
  • Validate all user input with typed requests
  • Use dependency injection over global state

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.
