Trust Assessment
onchainkit received a trust score of 10/100, placing it in the Untrusted category. This skill has significant security findings that require attention before use in production.
SkillShield's automated analysis identified 28 findings: 19 critical, 7 high, 1 medium, and 1 low severity. Key findings include Arbitrary command execution, File read + network send exfiltration, Dangerous call: subprocess.run().
The analysis covered 4 layers: dependency_graph, llm_behavioral_safety, manifest_analysis, static_code_analysis. The manifest_analysis layer scored lowest at 0/100, indicating areas for improvement.
Last analyzed on February 15, 2026 (commit 66de0a1e). SkillShield performs automated 4-layer security analysis on AI skills and MCP servers.
