Aniworld Web Application Development Instructions

This document provides detailed tasks for AI agents to implement a modern web application for the Aniworld anime download manager. All tasks should follow the coding guidelines specified in the project's copilot instructions.

Project Overview

The goal is to create a FastAPI-based web application that provides a modern interface for the existing Aniworld anime download functionality. The core anime logic should remain in SeriesApp.py while the web layer provides REST API endpoints and a responsive UI.

Architecture Principles

• Single Responsibility: Each file/class has one clear purpose
• Dependency Injection: Use FastAPI's dependency system
• Clean Separation: Web layer calls core logic, never the reverse
• File Size Limit: Maximum 500 lines per file
• Type Hints: Use comprehensive type annotations
• Error Handling: Proper exception handling and logging

Additional Implementation Guidelines

Code Style and Standards

• Type Hints: Use comprehensive type annotations throughout all modules
• Docstrings: Follow PEP 257 for function and class documentation
• Error Handling: Implement custom exception classes with meaningful messages
• Logging: Use structured logging with appropriate log levels
• Security: Validate all inputs and sanitize outputs
• Performance: Use async/await patterns for I/O operations

📞 Escalation

If you encounter:

• Architecture issues requiring design decisions
• Tests that conflict with documented requirements
• Breaking changes needed
• Unclear requirements or expectations

Document the issue and escalate rather than guessing.

Testing Guidelines for AI Agents

When implementing these tests:

1. Use existing fixtures from tests/conftest.py - db_session, app, mock_config
2. Mock external services - TMDB API, SMTP, Redis, webhooks
3. Test both happy paths and edge cases - success, errors, timeouts, retries
4. Verify database state - Use db_session to check persisted data
5. Test async code - Use pytest.mark.asyncio and proper async test patterns
6. Measure coverage - Run pytest --cov to verify targets met
7. Document test intent - Use clear test names and docstrings
8. Follow project conventions - 80+ line limit per test method, clear arrange-act-assert pattern

Execution Order

1. Start with Phase 1 (P0) - These are critical for production stability
2. Then Phase 2 (P1) - Core features depend on these
3. Then Phase 5 (P1) - End-to-end validation
4. Then Phase 3 (P2) - Performance and optimization
5. Finally Phase 4 (P3) - Observability and monitoring

Run tests continuously: pytest tests/ -v --cov --cov-report=html after each task completion.
