Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# anti-cheat

## Core Philosophy
In multiplayer games, the client is fundamentally compromised. The game executable runs in a hostile environment controlled by the user: memory can be modified via Cheat Engine, network packets can be intercepted, and GPU rendering pipelines can be injected with custom shaders. True anti-cheat engineering does not rely on invasive kernel drivers alone; it is built on an uncompromising architectural foundation: **Server Authority**. The client only sends input intentions; the authoritative server simulates physics, validates mechanics, and adjudicates reality.

---

## 4-Step Server-Authoritative Anti-Cheat Architecture

### Step 1: Server Authority & Movement Validation
1. **Never Trust Client Coordinates**:
   - The client must never send absolute positional updates (`player.position = x, y, z`).
   - The client sends raw input vectors (Move forward, Jump, Delta time). The server simulates physics and returns authoritative state.
2. **Speed-Hack & Teleportation Prevention**:
   - Server tracks positional displacement per tick:
     $$\Delta d \le v_{text{max}}  imes \Delta t + \epsilon_{text{threshold}}$$

How to install

The exact contents, by fingerprint
mdr add poorvith-mp/skills-gamedev/anti-cheat@sha256:54951e025eaf4062

The line at the top of this page pins the label git:20260912.4cb57a5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
