qa
Systematically QA test a web application and fix bugs found. (gstack)
Low
Low-risk findings.
2 low severity findings. Worth noting, but not necessarily harmful.
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
In `/qa` the workflow navigates to a user-supplied or detected Target URL via the browser (the `$B goto <target-url>` / `$B goto <page-url>` paths) and then uses `$B snapshot`/`$B snapshot -a` output reads, so outsider-authored web page text can be ingested at runtime.
W012: Unverifiable external dependency detected (runtime URL that controls agent).
What this means
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.
Why it was flagged
The skill downloads and executes a remote installer at runtime via curl -fsSL "https://bun.sh/install" and then runs it (bash "$tmpfile"), so https://bun.sh/install is fetched and executed during skill setup.
