particles-review

particles-review is a skill for Claude Code, Codex from valkor-ai/loom. It costs 85 tokens per session (345 once invoked), scanned A, original, Apache-2.0.

A post-implementation review for Godot particle effects, which are systems that create repeated visuals such as smoke, sparks, or rain. It checks particle nodes, materials, trails, sub-emitters, collisions, and runtime controls for known mistakes.

In plain words
What is it for?
Use it to review 2D or 3D Godot particle code, identify specific known pitfalls, show the affected code, and suggest fixes.
Why use it?
It catches common particle setup errors after the code has been written, before they become harder to diagnose in the project.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

particles-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

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.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
