description	Reviews Godot physics implementation for known pitfalls. Triggers AFTER implementation, when code involves CollisionObject2D, RigidBody2D, CharacterBody2D, Area2D, collision layers, or physics callbacks. Do NOT use this skill for planning or teaching — only for post-implementation review.

Physics Review

Post-implementation reviewer for Godot physics code. Checks against known gotchas that LLMs consistently get wrong.

When to trigger

After physics-related code is written or modified. Look for:

• Physics body nodes (StaticBody2D, RigidBody2D, CharacterBody2D, Area2D)
• Collision layer/mask assignments
• Physics callbacks (body_entered, body_exited, area_entered, area_exited)
• _physics_process() with velocity/damping logic
• Objects spawned near Area2D

Review process

1. Read gotchas.md
2. Scan the implemented code against each gotcha
3. For each hit:
   • Cite the gotcha ID (e.g. G1)
   • Show the offending code
   • Provide the fix
4. If no hits, report clean
5. Optionally run checklist.md static checks for automated verification

When you need specific API details, delegate to the godot-api skill.
