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 file instructs the agent to embed an invisible marker (<gstack-qid:...> wrapped in angle brackets) into user-facing AskUserQuestion text so hooks can auto-identify and auto-decide, which is a hidden/deceptive instruction that alters output visibility and behavior outside the skill's stated design-exploration 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
/design-shotgun: comparison-board feedback comments and preferences are received from the browser-served HTTP board and then ingested by the workflow via reading $_DESIGN_DIR/feedback*.json (cat of user-authored free text coming from the outside UI).
