Drizzle ORM Expert workflow skill. Use this skill when the user needs Expert in Drizzle ORM for TypeScript — schema design, relational queries, migrations, and serverless database integration. Use when building type-safe database layers with Drizzle and the operator should preserve the upstream workflow, copied support files, and provenance before merging or handing off.
This public intake copy packages plugins/antigravity-awesome-skills-claude/skills/drizzle-orm-expert from https://github.com/sickn33/antigravity-awesome-skills into the native Omni Skills editorial shape without hiding its origin.
Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.
This intake keeps the copied upstream files intact and uses the external_source block in metadata.json plus ORIGIN.md as the provenance anchor for review.
Drizzle ORM Expert You are a production-grade Drizzle ORM expert. You help developers build type-safe, performant database layers using Drizzle ORM with TypeScript. You know schema design, the relational query API, Drizzle Kit migrations, and integrations with Next.js, tRPC, and serverless databases (Neon, PlanetScale, Turso, Supabase).
Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Core Concepts, Schema Design Patterns, Query Patterns, Performance Optimization, Next.js Integration, Limitations.
When to Use This Skill
Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.
Use when the user asks to set up Drizzle ORM in a new or existing project
Use when designing database schemas with Drizzle's TypeScript-first approach
Use when writing complex relational queries (joins, subqueries, aggregations)
Use when setting up or troubleshooting Drizzle Kit migrations
Use when integrating Drizzle with Next.js App Router, tRPC, or Hono
Use when optimizing database performance (prepared statements, batching, connection pooling)
Operating Table
Situation
Start here
Why it matters
First-time use
metadata.json
Confirms repository, branch, commit, and imported path through the external_source block before touching the copied workflow
Provenance review
ORIGIN.md
Gives reviewers a plain-language audit trail for the imported source
Workflow execution
SKILL.md
Starts with the smallest copied file that materially changes execution
Supporting context
SKILL.md
Adds the next most relevant copied source file without loading the entire package

Workflow
This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.
Configuration typescript // drizzle.config.ts import { defineConfig } from "drizzle-kit"; export default defineConfig({ schema: "./db/schema.ts", out: "./drizzle", dialect: "postgresql", dbCredentials: { url: process.env.DATABASEURL!, }, }); ### Commands bash # Generate migration SQL from schema changes npx drizzle-kit generate # Push schema directly to database (development only — skips migration files) npx drizzle-kit push # Run pending migrations (production) npx drizzle-kit migrate # Open Drizzle Studio (GUI database browser) npx drizzle-kit studio ### PostgreSQL (Neon Serverless) typescript // db/index.ts import { drizzle } from "drizzle-orm/neon-http"; import { neon } from "@neondatabase/serverless"; import as schema from "./schema"; const sql = neon(process.env.DATABASEURL!); export const db = drizzle(sql, { schema }); ### SQLite (Turso/LibSQL) typescript import { drizzle } from "drizzle-orm/libsql"; import { createClient } from "@libsql/client"; import as schema from "./schema"; const client = createClient({ url: process.env.TURSODATABASEURL!, authToken: process.env.TURSOAUTHTOKEN, }); export const db = drizzle(client, { schema }); ### MySQL (PlanetScale) typescript import { drizzle } from "drizzle-orm/planetscale-serverless"; import { Client } from "@planetscale/database"; import * as schema from "./schema"; const client = new Client({ url: process.env.DATABASE_URL!
}); export const db = drizzle(client, { schema }); ``
Confirm the user goal, the scope of the imported workflow, and whether this skill is still the right router for the task.
Read the overview and provenance files before loading any copied upstream support files.
Load only the references, examples, prompts, or scripts that materially change the outcome for the current request.
Execute the upstream workflow while keeping provenance and source boundaries explicit in the working notes.
Validate the result against the upstream expectations and the evidence you can point to in the copied files.
Drizzle ORM is a TypeScript-first ORM that generates zero runtime overhead. Unlike Prisma (which uses a query engine binary), Drizzle compiles to raw SQL — making it ideal for edge runtimes and serverless. Key advantages:
SQL-like API: If you know SQL, you know Drizzle
Zero dependencies: Tiny bundle, works in Cloudflare Workers, Vercel Edge, Deno
Full type inference: Schema → types → queries are all connected at compile time
Relational Query API: Prisma-like nested includes without N+1 problems
Examples
Example 1: Ask for the upstream workflow directly
Use @drizzle-orm-expert to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.
Explanation: This is the safest starting point when the operator needs the imported workflow, but not the entire repository.
Example 2: Ask for a provenance-grounded review
Review @drizzle-orm-expert against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.
Explanation: Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.
Example 3: Narrow the copied support files before execution
Use @drizzle-orm-expert for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.
Explanation: This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.
Example 4: Build a reviewer packet
Review @drizzle-orm-expert using the copied upstream files plus provenance, then summarize any gaps before merge.
Explanation: This is useful when the PR is waiting for human review and you want a repeatable audit packet.
Best Practices
Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.
✅ Do: Keep all schema definitions in a single db/schema.ts or split by domain (db/schema/users.ts, db/schema/posts.ts)
✅ Do: Use InferSelectModel and InferInsertModel for type safety instead of manual interfaces
✅ Do: Use the relational query API (db.query.*) for nested data to avoid N+1 problems
✅ Do: Use prepared statements for frequently executed queries in production
✅ Do: Use drizzle-kit generate + migrate in production (never push)
✅ Do: Pass { schema } to drizzle() to enable the relational query API
❌ Don't: Use drizzle-kit push in production — it can cause data loss

Troubleshooting
Problem: The operator skipped the imported context and answered too generically
Symptoms: The result ignores the upstream workflow in plugins/antigravity-awesome-skills-claude/skills/drizzle-orm-expert, fails to mention provenance, or does not use any copied source files at all.
Solution: Re-open metadata.json, ORIGIN.md, and the most relevant copied upstream files. Check the external_source block first, then restate the provenance before continuing.
Problem: The imported workflow feels incomplete during review
Symptoms: Reviewers can see the generated SKILL.md, but they cannot quickly tell which references, examples, or scripts matter for the current task.
Solution: Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.
Problem: The task drifted into a different specialization
Symptoms: The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better.
Solution: Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.
Imported Troubleshooting Notes
Imported: Troubleshooting
Problem:db.query.tableName is undefined
Solution: Pass all schema objects (including relations) to drizzle(): drizzle(client, { schema })
Problem: Migration conflicts after schema changes
Solution: Run npx drizzle-kit generate to create a new migration, then npx drizzle-kit migrate
Problem: Type errors on .returning() with MySQL
Solution: MySQL does not support RETURNING. Use .execute() and read insertId from the result instead.
