Code Quality Standards

Quick Commands

composer lint           # Check PHP style (local, fastest)
composer lint-fix       # Auto-fix PHP issues (local)
npm run php:lint        # Same check, in Docker
npm run php:lint-fix    # Same fix, in Docker
npm run php:phpstan     # Static analysis
npm run lint:js         # JavaScript
npm run lint:css        # CSS

Always run phpstan via npm run php:phpstan. Bare vendor/bin/phpstan analyse crashes a worker at the default 128M and still crashes at 1G; the npm script passes the 2048M that actually works.

Project-Specific Rules

Area	Standard
PHP	7.4+, WordPress Coding Standards
Prefixes	sh, simplehistory, simple_history
Text domain	simple-history
CSS naming	SuitCSS: sh-ComponentName-subpart
Array syntax	Short [] not array()
Control structures	Always use braces {}, never colon syntax

Essential Principles

1. Always escape output - Use WordPress escaping functions
2. Prefix everything - All hooks, functions, classes
3. Run tools after changes - phpcs/phpstan before committing

Detailed Guidelines

• php-standards.md - PHP style, happy path, early returns
• css-standards.md - SuitCSS naming conventions
• js-standards.md - JavaScript conventions
• tooling.md - phpcs, phpstan, rector usage
• design-principles.md - DRY, YAGNI, refactoring patterns
