1 medium severity finding. This skill can be installed but you should review these findings before use.
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.
Potentially malicious external URL detected (high risk: 0.80). The RAG code calls Azure Cognitive Search at runtime (endpoint shown as https://your-search.search.windows.net) to fetch documents that are concatenated into the model context and thus directly control prompts, and the skill's RAG flow depends on that external content.
