Django Explorer Skill

Fast exploration and Q&A for juntossomosmais Django applications

Purpose

This skill provides rapid exploration and quick answers about Django/Python applications following juntossomosmais architecture patterns. Perfect for understanding project structure, locating components, and getting oriented in existing codebases.

Core Capabilities

Fast Project Discovery

• App Structure Analysis: Identifies all Django apps and their purposes
• Component Location: Quickly finds models, views, serializers, consumers, and tests
• URL Pattern Discovery: Maps out API endpoints and routing
• Dependency Identification: Analyzes installed packages and requirements
• Configuration Overview: Understands settings, environment variables, and deployment setup

Architecture Understanding

• Messaging Patterns: Identifies STOMP/RabbitMQ usage (django-stomp vs django-outbox-pattern)
• Authentication Setup: Maps out DRF authentication classes and permissions
• Database Configuration: Understands replica/default routing and connection setup
• Health Check Systems: Identifies monitoring and health check implementations
• Background Tasks: Locates Django-Q workers and job definitions

Quick Code Analysis

• Model Relationships: Maps entity relationships and StandardModelMixin usage
• API Endpoint Overview: Summarizes available endpoints and their purposes
• Business Logic Flow: Traces request/response paths through the application
• Integration Points: Identifies external service connections and callbacks
• Error Handling: Locates exception handling and logging patterns

Key Architecture Patterns

StandardModelMixin Usage

# All models inherit from StandardModelMixin
class AuditAction(StandardModelMixin):
    # Provides: id (UUID), created_at, updated_at
    user_id = models.CharField(max_length=128)
    action = models.CharField(max_length=128)
    success = models.BooleanField()

STOMP Messaging Patterns

# Legacy: django-stomp
from django_stomp.builder import build_publisher

# Newer: django-outbox-pattern
from django_outbox_pattern.models import Published

DRF Authentication Classes

# Customer authentication
authentication_classes = (LvJWTAuthentication,)

# Seller authentication  
authentication_classes = (LVJWTSellerAuthentication,)

# Callback authentication
authentication_classes = (TokenAuthentication,)

Health Check Integration

# Custom health checks for STOMP and database
from django_template.support.healthcheck.checkers import (
    DjangoSTOMPHealthCheck,
    DjangoOutboxPatternHealthCheck,
    CustomDatabaseBackendHealthCheck
)

Configuration Patterns

Environment Variable Handling

# Required environment variables
USER_API_HOST = getenv_or_raise_exception("USER_API_HOST")

# Boolean environment variables  
DEBUG = strtobool(os.getenv("DJANGO_DEBUG", "False"))

# Boolean with default
USE_DEBUG_APPS = eval_env_as_boolean("USE_DEBUG_APPS", False)

Database Configuration

# Primary and replica database setup
DATABASES = {
    "default": {...},  # Write operations
    "replica": {...}   # Read operations (when enabled)
}
DATABASE_ROUTERS = ["django_template.support.db_router.DatabaseRouter"]

Fast Exploration Commands

Project Overview

• "What Django apps are in this project?"
• "Show me the main API endpoints"
• "What messaging patterns does this use?"
• "How is authentication configured?"
• "What external services does this integrate with?"

Component Discovery

• "Where are the models defined?"
• "Show me all the DRF serializers"
• "Find the STOMP consumers"
• "Where are the health checks implemented?"
• "What background tasks are configured?"

Configuration Analysis

• "What environment variables are required?"
• "How is the database configured?"
• "What's the logging setup?"
• "Show me the middleware stack"
• "What debug tools are available?"

Architecture Questions

• "How does the request flow work?"
• "What's the database routing strategy?"
• "How are permissions handled?"
• "Where is error handling implemented?"
• "What monitoring is in place?"

Integration with Other Skills

This skill works as the entry point for Django application analysis:

1. Fast Exploration - Use this skill for initial discovery and quick questions
2. Deep Analysis - Reference django-analyzer skill when detailed investigation is needed
3. Documentation - Reference django-documenter skill when comprehensive documentation is required
4. Library Validation - Reference library-checker skill when validating dependencies

Common Use Cases

New Developer Onboarding

"I'm new to this codebase. Can you give me an overview?"
→ Analyzes app structure, main components, and key patterns
→ Identifies entry points and important files to understand
→ Explains the messaging and authentication patterns used

Bug Investigation Quick Start

"Where would I find the code that handles user authentication?"
→ Locates authentication views, middleware, and configuration
→ Explains the JWT authentication flow
→ Points to related consumers and external integrations

Feature Planning

"What patterns should I follow to add a new API endpoint?"
→ Shows existing endpoint patterns and DRF usage
→ Explains serializer and view conventions
→ Identifies URL routing and authentication requirements

Deployment Understanding

"How is this application deployed and configured?"
→ Analyzes Dockerfile, docker-compose, and scripts
→ Explains environment variable requirements
→ Shows health check and monitoring setup

Performance & Efficiency

Search Strategy

• Semantic Search: For conceptual queries and pattern identification
• File Search: For specific component location (models, views, etc.)
• Grep Search: For configuration values and specific code patterns
• Targeted Reading: Only reads relevant files based on query context

Response Format

• Quick Summaries: Concise overviews perfect for orientation
• File Locations: Precise paths to relevant code
• Key Insights: Important patterns and conventions identified
• Next Steps: Guidance for deeper investigation when needed

Integration Efficiency

• Smart Routing: Determines when to escalate to deeper analysis skills
• Context Preservation: Maintains exploration context for follow-up questions
• Pattern Recognition: Leverages juntossomosmais-specific knowledge for faster analysis
