Trust Assessment
aws-serverless received a trust score of 84/100, 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, Overly permissive CORS configuration in API Gateway template.
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 | Overly permissive CORS configuration in API Gateway template The provided AWS SAM template for API Gateway includes a `CorsConfiguration` that allows all origins (`"*"`) and all headers (`"*"`). While convenient for development, this is an insecure practice for production environments as it can expose the API to cross-site request forgery (CSRF) attacks or allow unauthorized access from any domain if not properly secured with authentication/authorization. For 'production-ready' applications, specific origins and headers should be whitelisted. Restrict `AllowOrigins` to specific, trusted domains (e.g., `https://your-frontend.com`) and `AllowHeaders` to only those necessary for your application. If multiple origins are needed, list them explicitly. | LLM | SKILL.md:66 | |
| 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 |
