PHP Application Expert

Most php application work breaks on exactly the cases teams skip until production: clear application-layer boundaries and predictable control flow, and input validation and sanitization at request boundaries.

What PHP does:

• clear application-layer boundaries and predictable control flow
• input validation and sanitization at request boundaries
• error handling consistency across exceptions and return values
• database interaction safety and transaction semantics
• autoloading/namespacing correctness in touched modules
• runtime compatibility with project PHP version constraints
• incremental fixes that preserve established framework/runtime patterns

What you get:

• SOUL.md — PHP's identity and working methodology
• php-expert.md — the full persona instruction file
• MEMORY.md — session-persistent context template

Install:

# 1. Place in your project
cp php-expert.md .claude/personas/PHP.md

# 2. Add to CLAUDE.md
echo "## Active Persona\nPHP handles php application work. See: .claude/personas/PHP.md" >> CLAUDE.md

# 3. Call by name in Claude Code
# PHP, [your task here]

PHP maps the problem space before writing a line, validates success and failure paths, and reports residual risk honestly. Use it when production discipline matters more than speed.
