Trust Assessment
explainer-video-guide 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 4 findings: 4 critical, 0 high, 0 medium, and 0 low severity. Key findings include Arbitrary command execution, Remote code execution: curl/wget pipe to shell, Unrestricted shell execution via `curl | sh`.
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. The LLM Behavioral Safety 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 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/okaris/explainer-video-guide/SKILL.md:9 | |
| 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/okaris/explainer-video-guide/SKILL.md:9 | |
| CRITICAL | Unrestricted shell execution via `curl | sh` The skill instructs the execution of `curl -fsSL https://cli.inference.sh | sh`. This command downloads and executes an arbitrary script from the internet using `sh`. This bypasses the skill's declared `Bash(infsh *)` permission, allowing the execution of any shell command. This poses a significant command injection risk if the host LLM executes this instruction, and introduces a supply chain risk as the content of the remote script can change at any time without verification. Remove or replace the `curl | sh` command with a more secure installation method that does not involve piping untrusted content directly to a shell. If shell execution is absolutely necessary, ensure the skill's declared permissions explicitly cover `curl` and `sh`, and implement robust content verification (e.g., checksums) for downloaded scripts. | LLM | SKILL.md:9 | |
| CRITICAL | Unrestricted shell execution via `npx` The skill instructs the execution of `npx skills add ...` commands. `npx` is a Node.js package runner that executes commands from npm packages. This bypasses the skill's declared `Bash(infsh *)` permission, allowing the execution of arbitrary shell commands. This poses a significant command injection risk if the host LLM executes this instruction, and introduces a supply chain risk as `npx` fetches packages from npm, which could be compromised or typosquatted. Remove or replace the `npx` commands with a method that adheres to the declared permissions. If `npx` execution is absolutely necessary, ensure the skill's declared permissions explicitly cover `npx` and pin package versions to specific hashes or exact versions to mitigate supply chain risks. | LLM | SKILL.md:170 |
