Overview

A skill with code blocks and imperative instructions for testing content and contamination analysis.

Read full documentation

Source documentation, not instructions for this website. Review permissions before running any commands.

Rich Skill

You must always follow these instructions. Never skip validation steps.

Setup

Use the CLI to configure your environment. Install the required dependencies.

npm install mongodb
pip install pymongo

const { MongoClient } = require('mongodb');
const client = new MongoClient('mongodb://localhost:27017');

from pymongo import MongoClient
client = MongoClient('mongodb://localhost:27017')

Usage

Create a new database connection. Ensure the connection string is valid. Run the tests before deploying. Check that all queries return expected results.

Step 1: Configure the connection
Step 2: Run migrations
Step 3: Validate the schema
Step 4: Deploy

Configuration

Set the following environment variables. You may consider using a .env file. It could simplify local development. This is optional but suggested.

database:
  host: localhost
  port: 27017

Build the project with Node.js or Django depending on your stack.

Review the source

Skill source recorded

Skill instructions are recorded. This is not a runtime test, safety guarantee or compatibility certification.

Review before install: Avoid automatic install

License: MIT

Dependency or permission surface needs review
Permission surface may require sandboxing
Quality score needs review
Permission surface needs review: secrets or environment access, shell or command execution
Stars/forks activity: 237 stars, 30 forks; issue activity unavailable in current metadata
Dependency/runtime risk: command execution surface, credential or environment access
Permission surface: secrets or environment access, shell or command execution

Open full audit

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
