Security
2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
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
Third-party content exposure detected (high risk: 0.90). The skill explicitly fetches Trello boards, lists, cards, and card details via MCP (see SKILL.md "Session Continuity" and the listed tools like get_cards_by_list_id and get_card_details), which are user-generated/untrusted third-party contents that the agent reads and uses to resume work and decide actions—so those external card/comments could inject instructions that influence the agent's behavior.
W012: Unverifiable external dependency detected (runtime URL that controls agent)
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
Potentially malicious external URL detected (high risk: 0.90). The skill launches an external MCP server at runtime using npx to fetch and execute the remote package @delorenj/mcp-server-trello (https://www.npmjs.com/package/@delorenj/mcp-server-trello), so it depends on and executes remote code fetched from an external source.
