ags-anti-ollvm

ags-anti-ollvm is a skill for Claude Code, Codex from 1llu50ry/mcp-gamehacking. It costs 44 tokens per session (195 once invoked), scanned A, original, MIT.

An Arm64 analysis framework for undoing OLLVM control-flow flattening, an obfuscation method that makes a program's execution paths harder to read. It simulates execution and rebuilds clearer if-else control-flow graphs from protected functions.

In plain words
What is it for?
Use it to analyze obfuscated Arm64 binaries, extract graphs with IDA, generate machine code with Keystone, and rebuild control-flow graphs.
Why use it?
It reduces the effort needed to understand obfuscated binary code during reverse engineering. Arm64 is the processor architecture used by many mobile and modern embedded devices.

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-anti-ollvm 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.

What it actually says

AntiOllvm

Author: IIIImmmyyy Source: mcp-gamehacking/skills/ags-anti-ollvm

Description

AntiOllvm is an Arm64 simulated execution framework for removing OLLVM control-flow flattening. It identifies dispatcher patterns and reconstructs complete if-else control-flow graphs from obfuscated functions. The core tool is written in C#, with companion Python scripts for IDA CFG extraction, machine-code generation via Keystone, and CFG rebuilding. It is primarily for reverse engineers analyzing obfuscated binaries in security and game-protection research.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

ags-anti-ollvm is a skill published in the GitHub repository 1llu50ry/mcp-gamehacking (344 stars, last pushed 2d ago), licensed MIT. It adds 44 tokens to every session and 195 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 2026-10-23.
