mongodb · hoodini — Claude Code skill: schemas, queries, aggregation
A skill that walks your agent through MongoDB and Mongoose: schema design, queries, indexes and update operators.
npx skills add hoodini/ai-agents-skills --skill mongodb -a claude-codeWhat mongodb does
The skill loads into your agent and supplies working TypeScript examples for MongoDB. Native driver setup covers MongoClient, client.db() and basic CRUD. The Mongoose part shows mongoose.connect with pool size and timeouts, connection event handlers, and closing the connection on SIGINT.
Schema design gets its own section: required fields, enum, select: false on passwords, timestamps, and indexes including compound and text. There is a clear split between embedding documents and referencing them with ObjectId plus populate, and virtuals for reverse references. Query operators follow — $gt, $in, $and, $or, $exists, $size, $text, $regex — along with updates like $set, $unset, $inc and $mul.
You need the packages installed first: npm install mongodb mongoose. The examples read the connection string from MONGODB_URI, so a project without that variable will need edits before anything runs. The skill text stops partway through the update operators, at $min — past that point your agent is on its own.
What it helps with
- design a Mongoose schema with validation and indexes
- decide between embedding a document and referencing it
- write a query with comparison and logical operators
- populate nested references with selected fields
- set up connection pooling and graceful shutdown
Example prompts for the agent
- Help me design a Mongoose User schema with indexes and a hidden password field
- Write a query using $or and $gte on createdAt
- How do I populate the author and comments on a Post?
