godot-genre-tower-defense — Claude Code skill for tower defense

What godot-genre-tower-defense does

The skill frames the genre as a loop: build, wave, defend, reward, harder waves. Most of the file is a list of things it tells the agent never to do. Towers have to fill different roles — aura slow, armor piercing, anti-air, burst sniper, splash damage — and early waves should not feel like filler, so an early-call bonus is expected.

Mazing gets its own section. Before a tower placement is committed, the agent is told to confirm a route to the exit still exists through NavigationServer2D.map_get_path(). Baking navigation synchronously is ruled out; bake_navigation_polygon() belongs on a worker thread, otherwise placement stutters the frame. Grid math stays in Vector2i/Vector3i rather than world coordinates.

Performance rules are strict. Calling get_overlapping_bodies() every frame is banned in favour of body_entered/body_exited signals feeding a local target cache. Target priorities use StringName values like &"first" and &"strongest", acquire searches are throttled across frames, and above 500 projectiles the skill routes them through PhysicsServer2D/3D with object pooling. Waves live in .tres resources instead of switch statements, and co-op purchases are validated server-side. The repo ships wave_manager.gd, tower.gd with an FSM, tower_targeting_system.gd, tower_defense_patterns.gd and grid_path_validator.gd, plus reference docs on architecture and mechanics.
