Credential access
highRefutedlow confidenceA reference-document code example demonstrates reading an API key from the environment via process.env.API_KEY in a private static field, an environment-credential access pattern not declared in the skill's description, though it is purely illustrative with no network sink and no instruction directing the agent to harvest credentials.
static #apiKey = process.env.API_KEY;
Why it was refuted
The flagged line is a fenced, purely illustrative private-static-field snippet in a language-feature documentation section; process.env is a core Node.js API squarely within the skill's declared 'Node.js APIs' scope, the example is fully surface-visible with no concealment, and it contains no sink or instruction to access or exfiltrate credentials, so the harm and undeclared gates fail and the chain gate fails as an absence.
