drizzle

drizzle is a skill for Claude Code from bobmatnyc/claude-mpm-skills. It costs 14 tokens per session (2,714 once invoked), scanned A, original, MIT.

A TypeScript database library that lets you describe tables and write SQL-like queries with type checking. It works with PostgreSQL, MySQL, and SQLite, including database migrations.

In plain words
What is it for?
Use it to define tables, connect to a database, insert and retrieve records, write typed queries, and manage schema changes with migrations.
Why use it?
It helps catch mismatches between application code and database columns before the code runs, while keeping queries close to SQL and adding little runtime overhead.

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

drizzle 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 9d ago.

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.

Drizzle ORM

Modern TypeScript-first ORM with zero dependencies, compile-time type safety, and SQL-like syntax. Optimized for edge runtimes and serverless environments.

Quick Start

Installation

# Core ORM
npm install drizzle-orm

# Database driver (choose one)
npm install pg            # PostgreSQL
npm install mysql2        # MySQL
npm install better-sqlite3 # SQLite

# Drizzle Kit (migrations)
npm install -D drizzle-kit

Basic Setup

// db/schema.ts
import { pgTable, serial, text, timestamp } from 'drizzle-orm/pg-core';

export const users = pgTable('users', {
  id: serial('id').primaryKey(),
  email: text('email').notNull().unique(),
  name: text('name').notNull(),
  createdAt: timestamp('created_at').defaultNow(),
});

// db/client.ts
import { drizzle } from 'drizzle-orm/node-postgres';
import { Pool } from 'pg';
import * as schema from './schema';

const pool = new Pool({ connectionString: process.env.DATABASE_URL });
export const db = drizzle(pool, { schema });

First Query

import { db } from './db/client';
import { users } from './db/schema';
import { eq } from 'drizzle-orm';

// Insert
const newUser = await db.insert(users).values({
  email: '[email protected]',
  name: 'John Doe',
}).returning();

// Select
const allUsers = await db.select().from(users);

// Where
const user = await db.select().from(users).where(eq(users.id, 1));

// Update
await db.update(users).set({ name: 'Jane Doe' }).where(eq(users.id, 1));

// Delete
await db.delete(users).where(eq(users.id, 1));

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.
