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 `scripts/agent.py`, the workflow ingests the caller-provided `domain` argument (`sys.argv[1]`) and then generates permutations and performs DNS resolution / `dnstwist -r` against those attacker-influenced domain strings at runtime, so outsider-submitted text (a domain string) drives what the LLM agent causes dnstwist to query and process.
