SkillShield's automated analysis identified 3 findings: 0 critical, 0 high, 3 medium, and 0 low severity. Key findings include Unsafe deserialization / dynamic eval, Suspicious import: urllib.request, Unpinned Dependency in Installation Instructions.
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 | |
|---|---|---|---|---|
| MEDIUM | Unsafe deserialization / dynamic eval Decryption followed by code execution Remove obfuscated code execution patterns. Legitimate code does not need base64-encoded payloads executed via eval, encrypted-then-executed blobs, or dynamic attribute resolution to call system functions. | Manifest | skills/nesdeq/serper/scripts/search.py:5 | |
| 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/nesdeq/serper/scripts/search.py:20 | |
| MEDIUM | Unpinned Dependency in Installation Instructions The skill's installation instructions recommend installing 'trafilatura' without specifying a version. This can lead to supply chain risks if a future version of the package introduces vulnerabilities, breaking changes, or malicious code. It also makes the skill's behavior non-deterministic across different environments. Pin the dependency version in the installation instructions. For example, `pip install trafilatura==X.Y.Z` or specify a version range like `trafilatura>=X.Y.Z,<A.B.C`. It is best practice to include a `requirements.txt` file with pinned versions. | LLM | scripts/search.py:23 |
