Trust Assessment
apple-media received a trust score of 28/100, placing it in the Untrusted category. This skill has significant security findings that require attention before use in production.
SkillShield's automated analysis identified 4 findings: 2 critical, 0 high, 2 medium, and 0 low severity. Key findings include Arbitrary command execution, Unpinned pyatv dependency, Dependency on external 'airfoil' skill.
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. The Manifest Analysis layer scored lowest at 40/100, indicating areas for improvement.
Last analyzed on February 13, 2026 (commit 13146e6a). SkillShield performs automated 4-layer security analysis on AI skills and MCP servers.
Layer Breakdown
Behavioral Risk Signals
Security Findings4
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| CRITICAL | Arbitrary command execution Node.js child_process require 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/officialpm/apple-media-officialpm/scripts/scan-json.js:7 | |
| CRITICAL | Arbitrary command execution Node.js synchronous shell execution 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/officialpm/apple-media-officialpm/scripts/scan-json.js:10 | |
| MEDIUM | Unpinned pyatv dependency The skill installs `pyatv` using `pipx install pyatv` without specifying a version. This can lead to supply chain risks where a future, potentially malicious or incompatible, version of `pyatv` could be installed, affecting the skill's security and stability. It is best practice to pin dependencies to specific versions. Pin the `pyatv` dependency to a specific, known-good version (e.g., `pipx install pyatv==X.Y.Z`). | LLM | SKILL.md:19 | |
| MEDIUM | Dependency on external 'airfoil' skill The skill delegates functionality to an external skill (`../airfoil/airfoil.sh`). This introduces a supply chain risk, as the security and behavior of this skill become dependent on the `airfoil` skill. If the `airfoil` skill is compromised or has excessive permissions, it could impact the security of this skill. Review the `airfoil` skill for security vulnerabilities and excessive permissions. Consider bundling necessary `airfoil` functionality directly or clearly documenting the security implications of this external dependency. | LLM | scripts/connect.sh:8 |
