E004: Prompt injection detected in skill instructions.
What this means
Detected a prompt injection in the skill instructions. The skill contains hidden or deceptive instructions that fall outside its stated purpose and attempt to override the agent’s safety guidelines or intended behavior.
Why it was flagged
The skill instructs the agent to embed a hidden marker ("<gstack-qid:{question_id}>") into user-facing questions that "doesn't render visibly to the user," which is an explicit hidden/deceptive instruction outside the stated deploy-configuration purpose.
Low
Low-risk findings.
1 low severity finding. 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 `/setup-deploy`, the runtime reads outsider-authored free text from the repository at execution time via `cat fly.toml` / `cat render.yaml` / `grep` on `.github/workflows/*.yml` to detect platform and deploy workflow details, which could include attacker-controlled content.
