exploit-check

exploit-check is a skill for Claude Code from CodePhobiia/claude-roblox-game-studio. It costs 29 tokens per session (604 once invoked), scanned A, original, MIT.

A Roblox game security audit that checks whether players can fake movement, remote requests, currency, items, or other game data.

In plain words
What is it for?
Use it to inspect client-side game changes, remote events, movement limits, trading, purchases, currency handling, and data protection.
Why use it?
It helps find places where the game trusts the player's device instead of checking actions on the server, which can allow cheating or duplicated items.

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

exploit-check 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 6d 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.

/exploit-check — Security Vulnerability Scan

Delegate to exploit-security-specialist agent to run a full audit.

Scan Areas:

1. Client Trust Analysis

  • Search for any client-side game state that the server doesn't validate
  • Check: currency changes, inventory modifications, health/damage
  • Flag any game.Players.LocalPlayer mutations that affect game state
grep -rn "LocalPlayer" src/StarterPlayer/ --include="*.lua" --include="*.luau"
grep -rn "Humanoid.Health\s*=" src/ --include="*.lua" --include="*.luau"

2. Remote Security

  • Run /remotes-audit as a sub-step
  • Additionally check for remotes that could be replayed or spoofed

3. Movement Security

  • Check if player position is server-validated
  • Check for speed limits, teleport distance limits
  • Identify if fly/noclip is preventable with current architecture
grep -rn "HumanoidRootPart.CFrame\s*=" src/
grep -rn "WalkSpeed\s*=\|JumpPower\s*=\|JumpHeight\s*=" src/

4. Economy Security

  • Check for item duplication vectors (race conditions in trades)
  • Check for negative quantity exploits
  • Verify MarketplaceService ProcessReceipt is server-authoritative
  • Check for currency overflow (number limits in Luau: 2^53)
grep -rn "ProcessReceipt" src/
grep -rn "UserOwnsGamePassAsync" src/

5. Data Security

  • Run /datastore-review as a sub-step
  • Check for data loss vectors
  • Verify no sensitive data in client-accessible locations (ReplicatedStorage, StarterGui, etc.)
grep -rn "ADMIN_LIST\|admin_list\|adminList" src/ReplicatedStorage/
grep -rn "API_KEY\|apikey\|api_key" src/

Output:

Generate an exploit report using .claude/docs/templates/exploit-report-template.md. Classify findings as Critical / High / Medium / Low.

Severity Classification

  • Critical: Data loss, account takeover, financial exploit, full admin escalation
  • High: Significant gameplay impact (god mode, unlimited currency, item dup)
  • Medium: Noticeable but limited (visual hacks that affect gameplay, rate limit bypass)
  • Low: Minor (UI manipulation that doesn't affect other players)

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.
