Design production-ready database schemas for SQL and NoSQL databases. Use when user asks to "design schema", "create tables", "database design", "ERD", "data model", or when starting a project that needs database structure. Triggers on "normalize", "migration plan", "index strategy", "테이블 설계".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Database Schema Designer Design production-ready database schemas with best practices built-in. --- ## Quick Start Just describe your data model: ``` design a schema for an e-commerce platform with users, products, orders ``` You'll get a complete SQL schema like: ```sql CREATE TABLE users ( id BIGINT AUTO_INCREMENT PRIMARY KEY, email VARCHAR(255) UNIQUE NOT NULL, created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ); CREATE TABLE orders ( id BIGINT AUTO_INCREMENT PRIMARY KEY, user_id BIGINT NOT NULL REFERENCES users(id), total DECIMAL(10,2) NOT NULL ); -- 인덱스는 CREATE TABLE 밖에 분리 (MySQL/PostgreSQL 모두 동작) CREATE INDEX idx_orders_user ON orders(user_id); ``` > 위 예시는 MySQL 기준입니다(`AUTO_INCREMENT`). PostgreSQL은 PK를 `BIGINT GENERATED ALWAYS AS IDENTITY`(또는 `BIGSERIAL`)로 쓰세요. 인덱스는 `CREATE INDEX`로 분리하면 양쪽에서 동작합니다(인라인 `INDEX ...`는 MySQL/MariaDB 전용 → Postgres 문법 에러). 이 스킬은 DB-First라 대상 DB에 맞춰 설계가 달라집니다. **What to include in your request:** - Entities (users, products, orders) - Key relationships (users have orders, orders have items) - Scale hints (high-traffic, millions of records) - Database preference (SQL/NoSQL) - defaults to SQL if not specified --- ## Triggers …

How to install
mdr add dannykkh/skill-olympus/database-schema-designer@sha256:653c3016d5a4c6eeThe line at the top of this page pins the label git:20261003.71f481b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
