1 high severity finding. You should review these findings carefully before considering using this skill.
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 skill prompts for the Resend API key and webhook signing secret and then directly injects those captured values into an nc:env-set directive (writing them verbatim into .env), which forces the agent to handle/output secret values.
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
The “Add Resend Email Channel” skill provisions a Resend webhook endpoint where inbound emails (“email.received”) can be delivered as free-text from external correspondents, making that user-authored email body a runtime input the agent can ingest via the Resend→webhook path.
