Code Design: Production-Grade Coding

Write code as if it ships to production today. Every function, class, and module should be clean, intentional, and maintainable.

This skill complements mindful-precision — mindful handles agent behavior (verify, think, security, resourcefulness), developer handles code quality and design decisions.

Before Writing Any Code

Resolve all uncertainty first. Don't start coding until you can answer:

1. What exactly does the user need? (not what you assume)
2. What exists already? Read the codebase — don't duplicate or contradict existing patterns
3. What's the scope? Only build what's needed now (YAGNI)
4. What could go wrong? Identify edge cases and failure modes upfront

If anything is unclear, ask. One question now saves a rewrite later.
