Drizzle ORM

Drizzle is a modern TypeScript ORM that is lightweight (~7.4kb minified+gzipped), tree-shakeable with zero dependencies, and serverless-ready by design. It supports PostgreSQL, MySQL, SQLite, SingleStore, MSSQL, and CockroachDB.

Research Process

To answer questions about Drizzle ORM, spawn a sub-agent to conduct thorough documentation research.

Launch a Research Sub-Agent

Use the Task tool to spawn a sub-agent dedicated to Drizzle documentation research. Do NOT specify a model (use the default model for comprehensive research quality).

Critical: Provide the sub-agent with a highly detailed prompt that includes:

Goal - What you are ultimately trying to accomplish
Context - Why you need this information and how it fits into the larger task
Specific Questions - Exactly what information you need answered
Output Requirements - The format and level of detail needed in the response

Task Tool Configuration

Task tool parameters:
- description: "Research Drizzle docs"
- subagent_type: "generalPurpose"
- model: (DO NOT SPECIFY - use default for thorough research)
- readonly: true
- prompt: (see template below)

Prompt Template for Sub-Agent

Structure your prompt to the research sub-agent as follows:
