database

A database-operation creator for software projects. It examines the database, ORM or ODM, models, migrations, and project structure before adding models, repositories, services, validation, tests, and migrations.

In plain words
What is it for?
Adding or improving operations for MongoDB, PostgreSQL, MySQL, or other databases using tools such as Prisma, TypeORM, Mongoose, Sequelize, or raw SQL.
Why use it?
It removes the need to guess how new database code should fit the existing connection, schema, and migration setup. It helps keep database changes consistent with the project.

Command for Claude Code

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

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

database 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 yesterday.

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.

Database Operations

Set up database operations for $ARGUMENTS following project conventions.

Task

Create or optimize database operations based on the requirements:

  1. Analyze existing database setup: Check current database configuration, ORM/ODM, and connection patterns
  2. Identify database type: Determine if using MongoDB, PostgreSQL, MySQL, or other database
  3. Examine ORM/ODM: Check for Prisma, TypeORM, Mongoose, Sequelize, or raw SQL patterns
  4. Review existing models: Understand current schema patterns and relationships
  5. Check migration system: Identify migration tools and patterns in use
  6. Implement operations: Create models, repositories, or services following project architecture
  7. Add validation: Include proper schema validation and constraints
  8. Create tests: Write database operation tests following project patterns
  9. Update migrations: Add necessary database migrations if schema changes required

Implementation Requirements

  • Follow project's database architecture patterns
  • Use existing ORM/ODM configuration and connection setup
  • Include proper TypeScript types for all database operations
  • Add comprehensive error handling and transaction management
  • Implement proper indexing for performance
  • Follow project's naming conventions for tables/collections and fields
  • Consider data validation at both application and database levels

Database Patterns to Consider

Based on your project setup:

  • Repository Pattern: Separate data access logic from business logic
  • Active Record: Models with built-in database operations
  • Data Mapper: Separate domain models from database schema
  • Query Builder: Fluent interface for building database queries
  • Raw SQL: Direct database queries for complex operations

Operation Types

Common database operations to implement:

  • CRUD operations: Create, Read, Update, Delete
  • Bulk operations: Batch inserts, updates, deletes
  • Aggregation: Complex queries with grouping and calculations
  • Relationships: Managing foreign keys and joins
  • Transactions: Ensuring data consistency
  • Migrations: Schema changes and data transformations

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.

database is a command published in the GitHub repository Justdvp/claude-code-templates (7 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 504 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
