W007: Insecure credential handling detected in skill instructions

What this means

The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.

Why it was flagged

Insecure credential handling detected (high risk: 1.00). The skill explicitly describes macros that read process.env keys and inline their values into bundled output (e.g., env("API_URL") -> const apiUrl = "https://..."; and requireEnv("API_SECRET")), which requires emitting secret/environment values verbatim into generated code, creating an exfiltration risk.

W011: Third-party content exposure detected (indirect prompt injection risk)

What this means

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.

Why it was flagged

Third-party content exposure detected (high risk: 0.90). The SKILL.md "Async Macros" example defines fetchSchema which uses fetch("https://api.example.com/schema.json") and inlines the fetched schema at build time, meaning external/untrusted HTTP responses can be read and materially influence generated code and subsequent build actions.
