Trust Assessment
appletv received a trust score of 10/100, placing it in the Untrusted category. This skill has significant security findings that require attention before use in production.
SkillShield's automated analysis identified 5 findings: 2 critical, 2 high, 0 medium, and 1 low severity. Key findings include Arbitrary command execution, Dangerous call: subprocess.run(), Unpinned dependency in installation instructions.
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 Findings5
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| CRITICAL | Arbitrary command execution Python shell execution (os.system, subprocess) 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/lucakaufmann/appletv/scripts/appletv.py:91 | |
| CRITICAL | Arbitrary command execution Python shell execution (os.system, subprocess) 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/lucakaufmann/appletv/scripts/appletv.py:202 | |
| HIGH | Dangerous call: subprocess.run() Call to 'subprocess.run()' detected in function 'run_atvremote'. This can execute arbitrary code. Avoid using dangerous functions like exec/eval/os.system. Use safer alternatives. | Static | skills/lucakaufmann/appletv/scripts/appletv.py:91 | |
| HIGH | Dangerous call: subprocess.run() Call to 'subprocess.run()' detected in function 'cmd_scan'. This can execute arbitrary code. Avoid using dangerous functions like exec/eval/os.system. Use safer alternatives. | Static | skills/lucakaufmann/appletv/scripts/appletv.py:202 | |
| LOW | Unpinned dependency in installation instructions The installation instructions for 'pyatv' do not specify a version, leading to the installation of the latest available version. This can introduce supply chain risks if a future version of 'pyatv' contains vulnerabilities or breaking changes, potentially affecting the skill's stability or security. While pipx provides isolation, the lack of version pinning means the skill's runtime environment is not fully deterministic. Pin the dependency to a specific version, e.g., `pipx install pyatv==X.Y.Z --python python3.11`, to ensure deterministic and secure installations. | LLM | SKILL.md:8 |
