Trust Assessment
youtube-transcript 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 8 findings: 3 critical, 4 high, 1 medium, and 0 low severity. Key findings include Arbitrary command execution, Dangerous call: subprocess.run(), Suspicious import: requests.
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. The Manifest Analysis layer scored lowest at 10/100, 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 Findings8
| 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/xthezealot/youtube-transcript/scripts/fetch_transcript.py:32 | |

Prefer library APIs over shell commands. | Manifest | skills/xthezealot/youtube-transcript/scripts/fetch_transcript.py:49 | |
| HIGH | Dangerous call: subprocess.run() Call to 'subprocess.run()' detected in function 'check_vpn'. This can execute arbitrary code. Avoid using dangerous functions like exec/eval/os.system. Use safer alternatives. | Static | skills/xthezealot/youtube-transcript/scripts/fetch_transcript.py:32 | |
| HIGH | Dangerous call: subprocess.run() Call to 'subprocess.run()' detected in function 'bring_up_vpn'. This can execute arbitrary code. Avoid using dangerous functions like exec/eval/os.system. Use safer alternatives. | Static | skills/xthezealot/youtube-transcript/scripts/fetch_transcript.py:48 | |

Use safer alternatives. | Static | skills/xthezealot/youtube-transcript/scripts/fetch_transcript.py:49 | |
| HIGH | Execution of privileged network commands The skill executes `wg-quick up` and `ip rule add` via `subprocess.run`. These commands are typically privileged operations that can reconfigure network interfaces and routing rules. This grants the skill excessive control over the host system's networking, which could be abused if the skill's execution environment has broad permissions (e.g., sudo access for these commands). While the arguments to these commands are hardcoded, the mere ability to execute them represents a significant privilege. Review the necessity of running these privileged commands. If essential, ensure the execution environment adheres strictly to the principle of least privilege. Consider running the skill in a container with restricted network capabilities or using a highly granular sudoers policy that only allows specific commands with specific arguments, rather than broad root access. | LLM | scripts/fetch_transcript.py:40 | |
| MEDIUM | Suspicious import: requests Import of 'requests' detected. This module provides network or low-level system access. Verify this import is necessary. Network and system modules in skill code may indicate data exfiltration. | Static | skills/xthezealot/youtube-transcript/scripts/fetch_transcript.py:7 |
