mobile-security

Guide for Android and iOS game security, reversing, and anti-cheat-adjacent platform research. Use this skill when working with APK or IPA analysis, IL2CPP mobile titles, Frida, Zygisk or Magisk, jailbreak or root detection bypass, Android kernel modules, emulator detection, or mobile anti-cheat systems.

Quality

Content

57%Weight 40%Scale 1-5

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

A broad, code-rich mobile security reference that is actionable and well-sectioned, but it is a long monolithic SKILL.md with redundant lists and no progressive disclosure into separate reference files or validation checkpoints in its workflows.

Suggestions

Move the long 'README Coverage' bullet catalog and per-tool code examples into a references/ file (e.g. references/tools.md) and keep SKILL.md as a concise overview with one-level-deep links.

Add explicit validation/verification checkpoints to the risky workflows (e.g. confirm injection success, verify stealth tier is active, re-check detection surface after bypass) so workflow_clarity can rise above 3.

Delete or merge the 'Resource Organization' recap with the Data Source section to remove redundant prose and tighten token efficiency.

Dimension	Reasoning	Score
Conciseness	Mostly efficient with concrete tool lists and code, but the duplicated 'README Coverage' bullet list, the redundant 'Resource Organization' recap, and some explanatory prose (e.g. eBPF advantages) could be trimmed without losing value.	3 / 5
Actionability	Provides mostly executable guidance — apktool/jadx commands, Frida interceptor snippets, /proc/pid/mem C code, Zygisk module structure, Logos hooks, SSL bypass — with only minor gaps (a few numbered workflows stay at the hint level).	4 / 5
Workflow Clarity	Sequences exist (IL2CPP, Unity, Unreal, managed instrumentation) but lack explicit validation/verification checkpoints for risky injection and root-bypass operations, so checkpoints are missing or only implicit.	3 / 5
Progressive Disclosure	Good section headers and external data-source URLs, but with no bundle files the entire ~540-line tool catalog and code reference is inlined in SKILL.md rather than split into one-level-deep reference files.	3 / 5

Description

100%Weight 40%Scale 1-5

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 explicitly covers both capabilities and use-when triggers with natural, comprehensive keywords and a clear distinct niche.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete capability areas — 'APK or IPA analysis', 'IL2CPP mobile titles', 'Frida, Zygisk or Magisk', 'jailbreak or root detection bypass', 'Android kernel modules', 'emulator detection', 'mobile anti-cheat systems' — with comprehensive coverage.	5 / 5
Completeness	Explicitly states both the 'what' ('Guide for Android and iOS game security, reversing, and anti-cheat-adjacent platform research') and the 'when' ('Use this skill when working with...') with concrete trigger phrases.	5 / 5
Trigger Term Quality	Natural user-facing terms including file extensions and tool names (APK, IPA, Frida, Zygisk, Magisk, jailbreak, root detection bypass, emulator detection) give comprehensive coverage of phrases a user would actually say.	5 / 5
Distinctiveness Conflict Risk	The mobile game security / anti-cheat niche is clearly scoped with distinct triggers (APK/IPA, IL2CPP, Frida, Zygisk/Magisk) and minimal overlap risk with other skills.	5 / 5
	Total	20 / 20 Passed
