MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.80). The skill instructs running "npx @shift-preflight/runtime proxy", which fetches and executes remote code from the npm registry (e.g. https://registry.npmjs.org/@shift-preflight%2Fruntime) and runs a local HTTP proxy that automatically modifies agent request payloads at runtime, so this external package controls/executes code affecting prompts.
