Security

1 high severity finding. You should review these findings carefully before considering using this skill.

High

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

The prompt's macro examples explicitly read process.env (and show requiring API_SECRET) and inline those values into generated code, which forces secret values to appear verbatim in the output.

Low

Low-risk findings.

1 low severity finding. Worth noting, but not necessarily harmful.

Low

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

The SKILL.md "Async Macros" section shows a macro that calls fetch("https://api.example.com/schema.json") and inlines the fetched schema at build time, so the bundling process can fetch and interpret remote (potentially untrusted) web content that can change build-time behavior.
