Trust Assessment
langfuse received a trust score of 85/100, 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, Hardcoded API Keys in Examples.
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 | Hardcoded API Keys in Examples The provided code examples demonstrate hardcoding API keys (`public_key` and `secret_key`) directly within the source code. While these are placeholders (`pk-...`, `sk-...`), this practice is a security anti-pattern. If a developer copies these examples and replaces the placeholders with actual credentials without using environment variables or a secure secret management system, it could lead to sensitive API keys being exposed in version control, logs, or other insecure locations. Advise developers to use environment variables (e.g., `os.getenv("LANGFUSE_PUBLIC_KEY")`) or a secure secret management system for API keys instead of hardcoding them. Update examples to reflect this best practice. | LLM | SKILL.md:19 | |
| 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 |
