backend-orm

backend-orm is a skill for Claude Code, Codex, Cursor from awesome-ai-dev/awesome-ai-dev. It costs 17 tokens per session (411 once invoked), scanned A, original, MIT.

A guide to object-relational mappers, or ORMs, which let application code work with database tables through models and queries. It covers Prisma, Drizzle, SQLAlchemy, and TypeORM.

In plain words
What is it for?
Use it to define models, relationships, types, and queries for Node.js or Python applications using the listed ORM tools.
Why use it?
It helps developers represent relationships and query databases without writing every operation as raw SQL, while choosing a suitable library for the project.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

backend-orm scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/orm.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

ORM 使用

Prisma (Node.js)

// Schema
model User {
  id    Int     @id @default(autoincrement())
  email String  @unique
  posts Post[]
}

model Post {
  id     Int    @id @default(autoincrement())
  title  String
  author User   @relation(fields: [authorId], references: [id])
  authorId Int
}

// 查询
const users = await prisma.user.findMany({
  include: { posts: true }
});

Drizzle (Node.js)

// Schema
export const users = pgTable('users', {
  id: serial('id').primaryKey(),
  email: varchar('email', { length: 255 }).unique(),
});

export type User = typeof users.$inferSelect;

// 查询
const result = await db.select().from(users).all();

SQLAlchemy (Python)

# Model
class User(Base):
    __tablename__ = 'users'
    
    id = Column(Integer, primary_key=True)
    email = Column(String, unique=True)
    posts = relationship('Post', back_populates='author')

# Query
users = session.query(User).all()

TypeORM (Node.js)

@Entity()
export class User {
  @PrimaryGeneratedColumn()
  id: number;
  
  @Column({ unique: true })
  email: string;
  
  @OneToMany(() => Post, post => post.author)
  posts: Post[];
}

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
