ags-anticheat-qa

ags-anticheat-qa is a skill for Claude Code, Codex from 1llu50ry/mcp-gamehacking. It costs 50 tokens per session (294 once invoked), scanned A, original, MIT.

A Fabric client mod for testing Minecraft anti-cheat systems. Fabric is a Minecraft modding platform, and anti-cheat software checks whether players are using prohibited tools or actions.

In plain words
What is it for?
It helps inspect movement, reach, rotation, clicks, velocity, network delay, frame rate, and game timing. It also provides visual overlays, local detection-event logging, and a probe for checking which world data the client can see.
Why use it?
It lets developers observe and safely simulate conditions that anti-cheat systems should detect without providing gameplay cheats or bypasses. This helps check whether server protections work as intended.

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

ags-anticheat-qa 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 2d 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.

Description

AntiCheat QA is a Fabric client mod for Minecraft 1.21.11 that helps developers observe, visualize, log, and safely simulate anti-cheat behavior without providing gameplay cheats or bypasses. Written in Java with Fabric API and mixins, it exposes a modular ClickGUI and HUD overlay with monitors for reach, movement, rotation, CPS, velocity, ping, FPS, and tick timing, plus visualization tools such as ESP, tracers, nametags, fullbright, and FreeCam. QA-focused modules include a dashboard overview, a test simulator for local detection-event logging, and a Y-Level Probe that counts client-visible blocks, chests, and entities below Y=0 to verify server-side data stripping. It is aimed at Minecraft server operators and anti-cheat engineers who need a dedicated client-side toolkit to validate that server protections work as intended.

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.
