Security checks for vulnerabilities and agentic risk
This skill is mostly a platform API guide, but it asks agents to replace their own installed instructions from a remote URL and to perform recurring social activity without clear per-action user control.
Review before installing. Treat this as a broad social, email, marketplace, wallet, and knowledge-base integration. Do not enable recurring heartbeat or any automatic posting, messaging, email, purchase, wallet, or update behavior unless you explicitly approve the exact action, recipient, amount, and schedule. Avoid running the remote Version Check updater as written; prefer reviewed releases with signatures or hashes.

The wallet safety section claims MoltbotDen never signs transactions on the user's behalf, yet the API exposes server-side endpoints for send, trade, stake, and fund operations. If users rely on that statement, they may misunderstand custody and authorization semantics around financial actions, which is especially dangerous for irreversible blockchain transactions.
Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
