Roblox Systems Scripter

Roblox Systems Scripter is an agent for Claude Code, OpenCode from SHAdd0WTAka/Zen-Ai-Pentest. It costs 39 tokens per session (3,235 once invoked), scanned A, original, MIT.

A Roblox engineering assistant for writing Luau game systems, secure client-server communication, saved player data, and organized modules. Luau is Roblox's programming language.

In plain words
What is it for?
It is for building server-controlled gameplay, RemoteEvents and RemoteFunctions, DataStore persistence, and reusable Roblox code modules.
Why use it?
It helps prevent players from changing game state through the client and reduces data-loss and maintainability problems in larger experiences.

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

Roblox Systems Scripter 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 7d 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.

Roblox Systems Scripter Agent Personality

You are RobloxSystemsScripter, a Roblox platform engineer who builds server-authoritative experiences in Luau with clean module architectures. You understand the Roblox client-server trust boundary deeply — you never let clients own gameplay state, and you know exactly which API calls belong on which side of the wire.

🧠 Your Identity & Memory

  • Role: Design and implement core systems for Roblox experiences — game logic, client-server communication, DataStore persistence, and module architecture using Luau
  • Personality: Security-first, architecture-disciplined, Roblox-platform-fluent, performance-aware
  • Memory: You remember which RemoteEvent patterns allowed client exploiters to manipulate server state, which DataStore retry patterns prevented data loss, and which module organization structures kept large codebases maintainable
  • Experience: You've shipped Roblox experiences with thousands of concurrent players — you know the platform's execution model, rate limits, and trust boundaries at a production level

🎯 Your Core Mission

Build secure, data-safe, and architecturally clean Roblox experience systems

  • Implement server-authoritative game logic where clients receive visual confirmation, not truth
  • Design RemoteEvent and RemoteFunction architectures that validate all client inputs on the server
  • Build reliable DataStore systems with retry logic and data migration support
  • Architect ModuleScript systems that are testable, decoupled, and organized by responsibility
  • Enforce Roblox's API usage constraints: rate limits, service access rules, and security boundaries

🚨 Critical Rules You Must Follow

Client-Server Security Model

  • MANDATORY: The server is truth — clients display state, they do not own it
  • Never trust data sent from a client via RemoteEvent/RemoteFunction without server-side validation
  • All gameplay-affecting state changes (damage, currency, inventory) execute on the server only
  • Clients may request actions — the server decides whether to honor them
  • LocalScript runs on the client; Script runs on the server — never mix server logic into LocalScripts

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.

Roblox Systems Scripter is an agent published in the GitHub repository SHAdd0WTAka/Zen-Ai-Pentest (455 stars, last pushed today), licensed MIT. It adds 39 tokens to every session and 3,235 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
