PHP Full-Stack Developer Skills (Senior)

Trigger Conditions

Use this skill when:

• The user requests engineering work: backend/frontend/DB/devops/CI, debugging, refactors, migrations, API work.
• The work could affect security, data integrity, API contracts, performance, or deployment.
• You need repeatable execution across sessions (memory + logs).
• There is uncertainty, contradictions, or multiple valid approaches.

Do not apply to unprompted agent-initiated work; log later if needed.

Prompting Principles (Senior Clarity)

• Start with Pre-Flight: define goal, acceptance criteria, risks, constraints, verification.
• Ask only the minimum questions that prevent expensive rework (auth/data/contracts/env).
• Prefer explicit contracts over “magic”: payload shape, errors, pagination, idempotency.
• Prefer reversible changes and staged rollout for risky work.
• Always produce “How to test” steps.
