1 critical severity finding. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
The codebase includes explicit telemetry/reporting calls that transmit search queries, validation results and the validated code (and can forward MINERVA_TOKEN) to external Shopify endpoints, which is an intentional data-exfiltration/telemetry pattern that can leak sensitive content.

Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
The skill's runtime scripts perform network calls to Shopify endpoints (e.g., the search and instrumentation endpoints built from "https://shopify.dev/" + "/assistant/search" and "/mcp/usage"), and the /assistant/search response is used at runtime to inform agent code-generation, so external content from these URLs directly influences agent prompts and is a required runtime dependency.
