Fix and improve this skill with Tessl
tessl review fix ./plugins/customaize-agent/skills/test-prompt/SKILL.mdW011: 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 required workflow described in SKILL.md only instructs creating baseline/green tests using a “Task tool” with attacker-provided scenario text, but it does not show any runtime step where outsider-authored free text from external public sources (queues/feeds/inboxes/tickets/GitHub/Jira) is automatically ingested without the tester selecting the scenario.
