Unity-AI-ParticleSystem CLAUDE.md

Unity-AI-ParticleSystem CLAUDE.md is an instructions file for coding agents from IvanMurzak/Unity-AI-ParticleSystem. It costs 384 tokens per session, scanned A, original, MIT.

A Unity package that lets AI agents inspect and modify Unity ParticleSystem components through two MCP tools. Unity ParticleSystem components create effects such as smoke, fire, and sparks.

In plain words
What is it for?
Use it when implementing or testing particle-system inspection and modification, updating its Unity-MCP dependency, or bumping the package version.
Why use it?
It provides documented rules for building, testing, and changing the package, including the requirement that Unity data access runs on Unity's main thread.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

Unity-AI-ParticleSystem CLAUDE.md 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

CLAUDE.md

What this is

Unity package com.ivanmurzak.unity.mcp.particlesystem exposing two MCP tools — particle-system-get and particle-system-modify — so AI agents can inspect and modify Unity ParticleSystem components. Built on the Unity-MCP platform.

Build / run

  • Package source: Unity-Package/Packages/com.ivanmurzak.unity.mcp.particlesystem/ (Editor + Runtime + Tests)
  • Update Unity-MCP dependency: .\commands\update-ai-game-developer.ps1 (-WhatIf to preview)
  • Bump version: .\commands\bump-version.ps1 -NewVersion "x.y.z" (-WhatIf to preview)
  • Tests run inside Unity Editor (NUnit + [UnityTest]); CI uses game-ci/unity-test-runner@v4.

Critical invariants

  • Main thread only. All Unity module reads/writes MUST be dispatched via MainThread.Instance.Run(...). ReflectorNet calls (reflector.Serialize, reflector.TryPopulate) touch Unity structs and must not run off the main thread.
  • Tools are partial classes on Tool_ParticleSystem — one op per file (ParticleSystem.Get.cs, ParticleSystem.Modify.cs).

Find detail in

  • docs/claude/architecture.md — repo structure, MCP tool registration, ReflectorNet usage, assemblies, tests
  • docs/claude/models.mdParticleSystemData, response types, GameObjectRef, ComponentRef
  • docs/claude/release.mdbump-version.ps1 and files it touches
  • docs/claude/ci.mdrelease.yml, test_unity_plugin.yml, Unity version matrix
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.
