Trust Assessment
agnxi-search received a trust score of 65/100, placing it in the Caution category. This skill has some security considerations that users should review before deployment.
SkillShield's automated analysis identified 2 findings: 1 critical, 0 high, 1 medium, and 0 low severity. Key findings include Suspicious import: urllib.request, Command Injection via `query` parameter in shell execution.
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 Findings2
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| CRITICAL | Command Injection via `query` parameter in shell execution The `search_agnxi` tool's `Usage Implementation` in `SKILL.md` directly interpolates the `query` parameter into a shell command (`python3 search.py "{{query}}"`). An attacker can inject arbitrary shell commands by crafting a malicious `query` string (e.g., `"; rm -rf /"`), leading to remote code execution on the host system. The `{{query}}` placeholder is not properly escaped before being passed to the shell. The `query` parameter must be properly escaped before being passed to the shell. If the agent framework executes this command, it should ensure that the `query` variable is shell-escaped (e.g., using `shlex.quote` in Python) before substitution. Alternatively, the command should be executed directly without an intermediate shell, passing arguments as a list (e.g., `subprocess.run(['python3', 'search.py', query_value])`). | LLM | SKILL.md:27 | |
| MEDIUM | Suspicious import: urllib.request Import of 'urllib.request' 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/doanbactam/agnxi-search-skill/search.py:3 |
