graphics-api-hooking

graphics-api-hooking is a skill for Claude Code from gmh5225/awesome-game-security. It costs 43 tokens per session (221 once invoked), scanned A, original, MIT.

A technical guide to intercepting graphics calls and drawing overlays in DirectX, OpenGL, and Vulkan. It also covers examining how a game's rendering pipeline produces frames.

In plain words
What is it for?
Use it when working with functions such as Present, SwapBuffers, draw calls, swap chains, shaders, overlays, screenshots, or graphics debugging in game-security research.
Why use it?
Graphics interception varies by API, driver, application, and capture tool, so the guide helps identify suitable hook points and avoid false conclusions.

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

graphics-api-hooking 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 1mo 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

Graphics API hooking and rendering

Record the API, backend, driver, compositor, capture path, synchronization model, and tool version before interpreting rendering evidence.

Topic routing

Use game-hacking-techniques for the broader attacker model and game-engine-resources for engine-owned rendering structures. Separate observed capture behavior from assumed anti-cheat enforcement.

Files

What ships with it

4 files 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.
