Android Reverse Engineering Skill is a Claude Code slash-command skill that gives the AI coding assistant a complete Android APK analysis toolkit. With a single command, Claude can decompile APKs with jadx, trace execution flows, extract hardcoded secrets, analyze manifest permissions, and produce structured security reports — turning a complex multi-tool forensic workflow into a conversational one. The skill integrates with Claude's coding agent to support interactive reverse engineering: ask Claude to trace how an API key is stored, follow a specific class hierarchy, or find all network calls in a third-party SDK. The workflow is designed for mobile security researchers, app auditors, and developers who want to understand dependencies embedded in their own apps. Trending on GitHub with 538 stars in its first day, this skill fills a niche where the intersection of LLMs and traditional security tooling has been underserved. As Claude Code gains ground in security workflows, specialized skills like this one — domain-specific tool orchestration through natural language — are becoming a new category of developer productivity.

qsag-core is a fresh open-source Python toolkit from Neoxyber that addresses the OWASP Top 10 for Agentic Applications 2026 — specifically the two fastest-growing attack vectors: MCP tool poisoning and prompt injection in AI agents. The library uses pattern-based detection (not ML-based, to minimize false positives) to scan 26 MCP tool poisoning patterns across 7 categories and detect 28+ prompt injection patterns across 9 threat categories. It also catches ghost agent attempts, credential harvesting, and memory poisoning in real time. The toolkit is available on PyPI, ships with cryptographic attestations, and is licensed under Apache 2.0. It was created in early April 2026, making it genuinely new-to-the-scene. The timing is significant: a recent Dark Reading poll found 48% of cybersecurity professionals now identify agentic AI as the #1 attack vector, up from a niche concern in 2025. Microsoft released a similar (but much larger-scope) Agent Governance Toolkit in early April, which validates the problem space but leaves room for nimble open-source tooling. qsag-core is early-stage — zero stars on GitHub as of today, minimal community traction, and no documented production deployments. But it addresses a problem that's going to become critical as MCP adoption accelerates. First-mover advantage in a niche that's about to explode.
Reviewer scorecard
“Jadx and apktool are already in my toolkit, but orchestrating a full RE workflow through Claude Code saves massive time. The ability to ask natural-language questions about decompiled code — 'where does this app send user data?' — is genuinely useful for third-party SDK audits.”
“I've been looking for exactly this since MCP started proliferating. Pattern-based detection over ML is the right call for security tooling — I can audit what it's flagging and why. Dropping this into my agent pipeline CI was a 30-minute job. The MCP tool poisoning scanner alone is worth it.”
“Automating APK reverse engineering with an AI that can be wrong is risky for security work. LLM hallucinations in code analysis can produce false-negative vulnerability reports. Treat this as an assist layer with human verification, not a replacement for proper SAST tooling.”
“Zero stars, no known production deployments, no security audit of the security tool itself — that's an uncomfortable situation. Pattern-based detection will generate false positives as MCP tool definitions grow more complex, and attackers who know about this scanner can trivially evade it. Treat as research, not production security.”
“Specialized Claude Code skills for security domains are the early form of what will become autonomous security agents. The commoditization of APK analysis through LLMs will democratize mobile security research for teams that couldn't previously afford dedicated reverse engineers.”
“MCP security is going to matter enormously as AI agents gain real-world tool access. The OWASP Top 10 for Agentic Applications is brand new and most teams haven't even read it. Getting familiar with these attack patterns now, before an incident forces the conversation, is table-stakes security hygiene.”
“Not directly relevant for creative workflows, though understanding what third-party SDKs in your own apps are doing is useful due diligence for indie developers. If you ship an app with unknown trackers, this skill could surface them fast.”
“Unless you're running AI agents in production that use MCP tools, this is highly specialized developer/security tooling. Relevant context for understanding AI agent risks, but not something most creatives will interact with directly.”
