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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00039 | $0.03235 |
| Opus 5.5 | $0.00016 | $0.01294 |
| Sonnet 5.5 | $0.00008 | $0.00647 |
| Haiku 4.5 | $0.00004 | $0.00324 |
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 1mo 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
LocalScriptruns on the client;Scriptruns 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 (499 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 5.5. 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.
