summary: Explicit static types everywhere, specific node types, EventBus for cross-system signals, scenes as skeletons, SRP scripts, observable errors. From v2 magic-civilization.
appliesTo: ["**/*.gd"]
rules:
  - id: explicit_types
    level: must
    text: "Explicit type on every var (`var x: Type`); no bare `var x = v`, no inferred `:=`, no `Variant` escapes (except a typed EventBus payload)."
  - id: specific_types
    level: must
    text: Use the specific type (`Node3D`, `AudioStreamPlayer`), never the general (`Node`). Typed arrays always (`Array[String]`, never bare `Array`).
  - id: typed_signatures
    level: must
    text: Every function has typed params and a return type (`-> void` when none).
  - id: refcounted_for_logic
    level: should
    text: "`RefCounted` for pure logic; `Node` only for scene-tree lifecycle. One script = one responsibility (no God Nodes)."
  - id: signals
    level: must
    text: Cross-system communication goes through the EventBus autoload only; intra-tree parent↔child direct signals are fine.
  - id: scenes_skeleton
    level: should
    text: ".tscn is structure/skeleton only; behavior is attached/wired at runtime in _ready()."
  - id: observable_errors
    level: must
    text: "push_error()/push_warning() on failure paths; never silent returns or empty error handlers. Safe-cast with null check + log on mismatch."
  - id: no_dead_code
    level: must
    text: "No `# TODO`, no `# gdlint:ignore`, no unused vars."
