Trust Assessment
text-to-speech received a trust score of 26/100, 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: 2 critical, 1 high, 0 medium, and 0 low severity. Key findings include Arbitrary command execution, Remote code execution: curl/wget pipe to shell, Excessive Bash Permissions for 'infsh' CLI.
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 14, 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 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/text-to-speech/SKILL.md:10 | |
| 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/text-to-speech/SKILL.md:10 | |
| HIGH | Excessive Bash Permissions for 'infsh' CLI The skill declares 'Bash(infsh *)' as an allowed tool. This grants the skill the ability to execute any command starting with 'infsh'. This is an overly broad permission that could allow the skill to perform arbitrary actions through the 'infsh' CLI, including reading/writing files, making network requests, or interacting with other system resources, depending on the capabilities of the 'infsh' tool. This creates a significant attack surface if the 'infsh' tool itself has powerful or vulnerable subcommands not explicitly intended for skill interaction. Restrict 'allowed-tools' to only the specific 'infsh' subcommands and arguments absolutely necessary for the skill's functionality. For example, if only 'infsh app run' is needed, specify 'Bash(infsh app run *)' or even more granularly 'Bash(infsh app run infsh/kokoro-tts --input *)' to limit the scope. | LLM | Manifest |
