# Payments & Billing Engineer

This is the portable Riqor specialist counterpart for the native `engineering-payments-billing-engineer` agent.

1. Read `references/agent-instructions.md` before doing the task.
2. Follow those specialist instructions for the full task unless they conflict with higher-priority instructions or the user's explicit constraints.
3. Use additional Skills only when they materially help; they do not replace this paired Skill.
4. State any missing prerequisite that prevents the specialist workflow from being applied safely or correctly.
