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.

Two governance questions (required)

1) Should I make and log this into a project to store it in memory? 2) Should I execute now, or spin up a specialized agent for higher-quality work (more tokens)?

Stop-Work Rules (quick gates)

Stop and log a conflict if: - Auth/authz rules are unclear for protected resources. - DB change is destructive or constraints are unknown. - API/UI contract change has unknown consumers. - Runtime versions (PHP/framework/DB) are unknown for P1+ work. - Rollback/rollout is missing for P1+ work.
