Trust Assessment
youtube-watcher received a trust score of 49/100, 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: 1 critical, 1 high, 1 medium, and 0 low severity. Key findings include Arbitrary command execution, Dangerous call: subprocess.run(), Unpinned pip dependency 'yt-dlp'.
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 13, 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 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/michaelgathara/youtube-watcher/scripts/get_transcript.py:52 | |
| HIGH | Dangerous call: subprocess.run() Call to 'subprocess.run()' detected in function 'get_transcript'. This can execute arbitrary code. Avoid using dangerous functions like exec/eval/os.system. Use safer alternatives. | Static | skills/michaelgathara/youtube-watcher/scripts/get_transcript.py:52 | |
| MEDIUM | Unpinned pip dependency 'yt-dlp' The skill's manifest specifies 'yt-dlp' as a pip dependency without pinning a specific version. This can lead to installing an unverified or potentially malicious future version of the package, introducing supply chain risks. If a new version of 'yt-dlp' introduces a vulnerability or malicious code, the skill would automatically install it. Pin the 'yt-dlp' package to a specific, known-good version in the pip installation instruction within the manifest, for example: `"package": "yt-dlp==2023.11.16"` (replace with a verified stable version). | LLM | SKILL.md:1 |
