Trust Assessment
device-testing received a trust score of 26/100, placing it in the Untrusted category. This skill has significant security findings that require attention before use in production.
SkillShield's automated analysis identified 3 findings: 2 critical, 1 high, 0 medium, and 0 low severity. Key findings include Arbitrary command execution, Remote code execution: curl/wget pipe to shell, Direct execution of remote script via curl | bash.
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. All layers scored 70 or above, reflecting consistent security practices.
Last analyzed on February 14, 2026 (commit 13146e6a). SkillShield performs automated 4-layer security analysis on AI skills and MCP servers.
Layer Breakdown
Behavioral Risk Signals
Security Findings3
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| CRITICAL | Arbitrary command execution Remote code download piped to interpreter Review all shell execution calls. Ensure commands are static (not built from user input), use absolute paths, and are strictly necessary. Prefer library APIs over shell commands. | Manifest | skills/anton-abyzov/sw-device-testing/SKILL.md:411 | |
| CRITICAL | Remote code execution: curl/wget pipe to shell Detected a pattern that downloads and immediately executes remote code. This is a primary malware delivery vector. Never pipe curl/wget output directly to a shell interpreter. | Static | skills/anton-abyzov/sw-device-testing/SKILL.md:411 | |
| HIGH | Direct execution of remote script via curl | bash The skill documentation includes an installation instruction for Maestro that pipes the output of `curl` directly into `bash`. This allows arbitrary code from an external URL (`https://get.maestro.mobile.dev`) to be executed on the system. If the AI agent or a user blindly follows this instruction, it poses a significant supply chain risk, as the content of the remote script could change or be compromised, leading to malicious code execution without prior review. Avoid piping `curl` output directly to `bash`. Instead, download the script to a temporary file, review its contents, and then execute it. For example: `curl -Ls "https://get.maestro.mobile.dev" > install-maestro.sh && less install-maestro.sh && bash install-maestro.sh`. Alternatively, use a trusted package manager if available for installation. | LLM | SKILL.md:291 |
