description	Reviews Godot Particles implementation for known pitfalls. Triggers AFTER implementation, when code involves GPUParticles2D, GPUParticles3D, CPUParticles2D, CPUParticles3D, ParticleProcessMaterial, trail_enabled, sub-emitters, GPUParticlesCollision, or particle amount/emission control. Do NOT use this skill for planning or teaching — only for post-implementation review.

Particles Review

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

When to trigger

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

• Particle nodes (GPUParticles2D, GPUParticles3D, CPUParticles2D, CPUParticles3D)
• ParticleProcessMaterial or shader_type particles
• Trail configuration (trail_enabled, use_particle_trails)
• Sub-emitter setup (sub_emitter_mode, sub_emitter_*)
• Collision nodes (GPUParticlesCollisionBox3D, GPUParticlesCollisionSphere3D, etc.)
• Runtime particle property changes (.amount, .emitting)

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.
