Use this skill when the task involves schema design, database migrations, query review, indexing strategy, or data access pattern definition.
Reference this skill by attaching skills/data-tier/SKILL.md to your agent context, or instruct the agent:
Use the data-tier skill. Apply the schema design template, migration template, and query review checklist to the data work being done.
| Template | Purpose |
|---|---|
schema-design-template.md | Schema design document: entities, attributes, relationships, constraints, and indexes |
migration-template.md | Migration scaffold with up/down blocks, rollback plan, and zero-downtime notes |
query-review-checklist.md | Query review checklist: N+1 check, index usage, pagination, explain plan guidance |
data-dictionary-template.md | Data dictionary: table, column, type, nullable, description, and example values |
This skill is designed to be used alongside the data-tier agent. The agent drives the workflow; this skill provides the reference templates and review checklists.
The data tier persists domain entities defined by the backend-dev agent. Changes to schema require coordination with the backend-dev agent to keep repository patterns aligned.
