Trust Assessment
nemo-guardrails received a trust score of 83/100, placing it in the Mostly Trusted category. This skill has passed most security checks with only minor considerations noted.
SkillShield's automated analysis identified 3 findings: 0 critical, 0 high, 2 medium, and 1 low severity. Key findings include Network egress to untrusted endpoints, Covert behavior / concealment directives, Unpinned dependency in manifest.
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 12, 2026 (commit 458b1186). 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 | Network egress to untrusted endpoints HTTP request to raw IP address Review all outbound network calls. Remove connections to webhook collectors, paste sites, and raw IP addresses. Legitimate API calls should use well-known service domains. | Manifest | cli-tool/components/mcps/devtools/figma-dev-mode.json:4 | |
| MEDIUM | Unpinned dependency in manifest The `nemoguardrails` dependency is specified without a version pin in the `dependencies` array of the manifest. This can lead to unexpected behavior or security vulnerabilities if a new, incompatible, or malicious version is released. It is best practice to pin dependencies to a specific version or a narrow version range to ensure deterministic builds and prevent supply chain attacks. Pin the `nemoguardrails` dependency to a specific version (e.g., `"nemoguardrails==0.9.0"`) or a narrow version range (e.g., `"nemoguardrails>=0.9.0,<1.0.0"`) in the manifest's `dependencies` array. | Static | SKILL.md:1 | |
| LOW | Covert behavior / concealment directives Multiple zero-width characters (stealth text) Remove hidden instructions, zero-width characters, and bidirectional overrides. Skill instructions should be fully visible and transparent to users. | Manifest | cli-tool/components/mcps/devtools/jfrog.json:4 |
