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.

Quality

Content

50%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A broad, concrete reference for graphics API hooking with useful code and a clear external data-source workflow, but it is over-long, contains partial/non-executable snippets, and references a wiki/ bundle that does not exist. Tightening inline content and either shipping or removing the wiki references would raise its quality.

Suggestions

Move the large inline reference catalogs (per-API hooks, overlay/shader techniques, OBS pipeline) into separate reference files and keep SKILL.md as a concise overview with one-level-deep links.

Either provide the referenced wiki/ files (wiki/overviews/graphics-api.md, wiki/index.md, wiki/AGENTS.md) or remove the dead references so navigation pointers resolve.

Make code examples complete and executable (real return values, required includes/declarations) or explicitly mark illustrative snippets as pseudocode.

Dimension	Reasoning	Score
Conciseness	The body is a ~480-line monolithic reference; while the specialized OBS/AI-pipeline detail earns its place, sections like World-to-Screen and overlay basics re-explain concepts Claude already knows and could be tightened.	2 / 3
Actionability	Many concrete code snippets are present, but several are partial or non-executable (e.g. 'return invalid', '// Render overlay here', missing includes/declarations); the archive/description fetch URLs are the most copy-paste-ready guidance.	2 / 3
Workflow Clarity	This is a reference catalog rather than a sequenced workflow; the only real sequence is the fetch priority order (description → archive → README), which lacks validation checkpoints.	2 / 3
Progressive Disclosure	Content is largely inline and monolithic, and the referenced wiki paths (wiki/overviews/graphics-api.md, wiki/index.md, wiki/AGENTS.md) point to no existing bundle directory, so the disclosure pointers are partly dead.	2 / 3
	Total	8 / 12 Passed

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, well-scoped description that states concrete capabilities and provides an explicit, natural-language trigger clause with good keyword coverage. It uses third-person voice and is unlikely to conflict with other skills.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'graphics API interception, overlay rendering, and render-pipeline analysis across DirectX, OpenGL, and Vulkan' — rather than vague language.	3 / 3
Completeness	Explicitly answers both what ('Guide for graphics API interception, overlay rendering, and render-pipeline analysis') and when ('Use this skill when working with ...'), with an explicit trigger clause.	3 / 3
Trigger Term Quality	Covers natural terms users would say: 'Present or SwapBuffers hooks, DXGI swap chains, shader or draw-call interception, screenshot-sensitive overlays, ... graphics debugging'.	3 / 3
Distinctiveness Conflict Risk	Occupies a clear niche (graphics API hooking for game security research) with distinct, specific triggers unlikely to fire for unrelated skills.	3 / 3
	Total	12 / 12 Passed
