Coding Standards

General Principles

Structure

• Prefer small, focused functions.
• Avoid deeply nested conditionals; use early returns.
• Extract reusable logic into shared modules.

Comments & Documentation

• Write comments to explain why, not what.
• Keep docstrings in sync with behavior; avoid outdated comments.

Error & Logging

• Use structured logging with consistent fields:
  • requestId, userId, component, severity
• Never log secrets, tokens, or sensitive PII.

Misc

• Avoid long parameter lists; group related values into objects.
• Prefer pure functions where practical.
• Add TODOs with owner and context, e.g.:
  • // TODO [owner]: [short description] ([ticket link])

Language-Specific Standards

For detailed language-specific conventions, see:

• Python - Includes modularization guidelines (500-800 lines ideal, 1000 max), black/ruff usage, PEP 8, type hints, and testing conventions
• Swift - iOS/macOS development standards, optionals, protocol-oriented programming, SwiftUI, and memory management
• Kotlin - Android development standards, coroutines, idiomatic Kotlin, null safety, and Jetpack Compose patterns
