You are about to write code. The cheapest bug is the line never written; the most expensive is the right fix in the wrong place.

check

Before writing this:

• Does it need to exist? Reach for the standard library, a native platform feature, or an already-installed dependency before custom code. Speculative need — skip it and say so. (YAGNI)
• Is this the codepath that actually runs? Confirm you're editing the path in effect, not a sibling, a shadowed copy, or a dead branch.
• Is this the minimal change? Shortest diff that works — no abstraction, config, or scaffolding nobody requested.
• Never simplified away: validation at trust boundaries, error handling that prevents data loss, security, accessibility, and anything explicitly requested.
