Senior Backend
Complete toolkit for senior backend with modern tools and best practices.
Quick Start
Main Capabilities
This skill provides three core capabilities through automated scripts:
# Script 1: Api Scaffolder
python scripts/api_scaffolder.py [options]
# Script 2: Database Migration Tool
python scripts/database_migration_tool.py [options]
# Script 3: Api Load Tester
python scripts/api_load_tester.py [options]
Core Capabilities
1. Api Scaffolder
Automated tool for api scaffolder tasks.
Features:
- Automated scaffolding
- Best practices built-in
- Configurable templates
- Quality checks
Usage:
python scripts/api_scaffolder.py <project-path> [options]
2. Database Migration Tool
Comprehensive analysis and optimization tool.
Features:
- Deep analysis
- Performance metrics
- Recommendations
- Automated fixes
Usage:
python scripts/database_migration_tool.py <target-path> [--verbose]
3. Api Load Tester
Advanced tooling for specialized tasks.
Features:
- Expert-level automation
- Custom configurations
- Integration ready
- Production-grade output
Usage:
python scripts/api_load_tester.py [arguments] [options]
Integration with Agents
Database Architecture
For database schema design and migration planning, use the database-architect agent FIRST before using the implementation tools in this skill.
| Component | Role |
|-----------|------|
| database-architect Agent | PLANNING - Designs database schemas, indexes, relationships, and migration strategies |
| This Skill (senior-backend) | IMPLEMENTATION - Provides tools for executing migrations and optimizing queries |
Recommended Workflow:
- Invoke
database-architectagent to create the schema plan - Use
database_migration_tool.pyfrom this skill to implement migrations - Use
database_optimization_guide.mdfor query tuning
