graphics-api-hooking
Guide for graphics API interception, overlay rendering, and render-pipeline analysis across DirectX, OpenGL, and Vulkan. Use this skill when working with Present or SwapBuffers hooks, DXGI swap chains, shader or draw-call interception, screenshot-sensitive overlays, or graphics debugging in game security research.

2 findings: 1 critical severity, 1 medium severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
This document contains explicit, actionable instructions for creating game-cheating overlays, evading anti-cheat (including kernel-level suppression), and remote pipelines that stream game frames and send remote input — behaviors that enable intentional malicious abuse and remote control.
W013: Attempt to modify system services in skill instructions.
What this means
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
Why it was flagged
The skill describes hooking system components (DWM, Steam/NVIDIA overlays), in-process injection, and explicitly mentions kernel-level techniques to block screenshot capture—actions that alter system behavior and typically require privileged/kernel-level code, so it poses a high risk of compromising the host state.
Low
Low-risk findings.
2 low severity findings. Worth noting, but not necessarily harmful.
W011: Third-party content exposure detected (indirect prompt injection risk).
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
The required runtime workflow describes fetching and parsing first-party curated resources from GitHub-hosted static “awesome-game-security” README/archive/description files (e.g., raw.githubusercontent.com URLs) rather than ingesting outsider-authored free text from a user-controlled feed or queue.
W012: Unverifiable external dependency detected (runtime URL that controls agent).
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
This skill explicitly instructs the agent to fetch remote README/archive/description files at runtime from raw.githubusercontent.com (e.g., https://raw.githubusercontent.com/gmh5225/awesome-game-security/refs/heads/main/README.md), which the agent would use to construct answers and thus directly control prompts/content from an external source.
