GDScript Mastery

Expert guidance for writing performant, maintainable GDScript — Godot-landmine decision trees, not a style-guide reprint.

Do NOT Load

• Do not load this skill for general prose style or Godot engine version upgrades (3→4 / 4.x hops) — those live in godot-version-migration (plus official upgrading guides via that hub).
• Do not preload every script below; open only the MANDATORY pointer for the Core Directive you are implementing.
• Do not treat EditorScript utilities (type_checker, performance_analyzer, signal_architecture_validator) as runtime gameplay code.

NEVER Do in GDScript
