Includes composer.json and project-structure templates (src/ for library code, tests/ wired via autoload-dev, PSR-4 namespace mapping), and the core PER/PSR-1 file rules (4 spaces, LF endings, no closing ?>).

Do NOT use this skill for language syntax or feature questions — that is php-language-modern. Do NOT use it for Laravel-specific conventions, which live in the Laravel plugin.

PHP Standards (PSR / PER / Composer)

Agent Workflow (MANDATORY)

Before applying a standard, spawn 3 agents in parallel, one Agent call each with a name:

1. fuse-ai-pilot:explore-codebase - Detect existing style config (.php-cs-fixer.php, phpcs.xml), composer.json autoload
2. fuse-ai-pilot:research-expert - Verify a PSR's current status on php-fig.org before recommending it
3. mcp__context7__query-docs - Cross-check composer.json schema

After changes, run fuse-ai-pilot:sniper for validation.
