Capability Boundaries

✅ Applicable Scenarios

• When you need to use the tech stack corresponding to this skill
• When the project needs to follow best practices
• When you need to get started quickly or deeply understand the core concepts

⚠️ Note

• Complex business logic needs to be adjusted according to specific scenarios
• Performance optimization needs to be evaluated based on the actual data volume

❌ Inapplicable Scenarios

• Irrelevant tech stacks or frameworks
• Special scenarios that require full customization

Common Pitfalls (Gotchas)

1. Version Compatibility: Pay attention to the compatibility between framework versions and dependency libraries; APIs may differ across versions
2. Configuration File Format: Configuration file format errors are the most common problem; it is recommended to use the editor's syntax check
3. Environment Variables: Ensure all necessary environment variables are set correctly, and do not hardcode sensitive information
4. Dependency Conflicts: Watch out for dependency conflicts when multiple versions coexist, and use a lock file to pin versions
5. Performance Pitfalls: Pay attention to performance optimization in large-data-volume scenarios, and avoid common problems such as N+1 queries

Usage Workflow

Step 1: Environment Preparation

Ensure the necessary dependencies and tools are installed in the development environment.

Step 2: Configuration Initialization

Perform basic configuration according to project requirements.

Step 3: Core Functionality Usage

Implement the core functionality according to the example code.

Step 4: Test Verification

Run tests to ensure the functionality works properly.

Step 5: Deployment and Release

After completing development, proceed with deployment and monitoring.
