PHP Patterns is a skill for Claude Code, Codex from AmariahAK/atlarix-skills. It costs 2 tokens per session (371 once invoked), scanned A, original, Apache-2.0.

A set of coding guidelines for modern PHP applications, including Laravel projects. It covers strict types, request validation, dependencies, errors, authorization, database safety, and tests.

In plain words
What is it for?
Use it when writing or reviewing PHP services, web applications, Laravel code, configuration, and tests.
Why use it?
It helps prevent unsafe input handling, hidden failures, unclear application structure, and dependency problems.

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 Patterns 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 3d 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.

What it actually says

PHP Patterns

When to use this skill

Use this skill when working in modern PHP (8+) codebases and you want predictable structure, safe IO boundaries, and maintainable application/service design.

Core patterns

Types and strictness

Prefer:

  • declare(strict_types=1); in new code where compatible
  • typed properties and return types
  • explicit DTOs for request/response boundaries

Composer hygiene

  • keep dependencies minimal
  • prefer stable versions
  • document required PHP version and extensions

Error handling

  • handle exceptions at module boundaries
  • avoid swallowing errors
  • log with context (no secrets)

Laravel-specific notes (if applicable)

  • controllers: thin
  • services: business logic
  • requests: validation
  • policies: authorization

Testing

  • unit tests for logic
  • integration tests for DB/wiring
  • keep fixtures small and deterministic

Atlarix tool notes

  • Explore: locate composer.json, framework entry points, and configuration.
  • Build: run composer install + the project’s test runner (phpunit/pest).
  • Debug: read stack traces and confirm config/env.
  • Review: check for injection risks and missing validation.

Common mistakes to avoid

  • Untyped arrays everywhere at boundaries
  • Mixing rendering, IO, and business logic
  • Swallowing exceptions

Mini-checklist

  • Boundary validation present
  • Types used for key functions
  • Tests cover critical flows
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.
