Overview

The skill is a plausible cross-posting helper, but it also directs agents to register a paid external posting service without clear approval or credential safeguards.

Review before installing. Use it only with accounts where you are comfortable granting posting authority, keep credentials out of chat and shell history, and do not register the ClawSwarm service unless you understand who can invoke it and can enforce explicit approval for every post.

Missing User Warnings

Medium

• Confidence: 94% confidence
• Finding: The skill explicitly encourages posting to multiple third-party platforms and handling API keys, bot tokens, and OAuth credentials, but provides no warning about external data transmission, credential sensitivity, or confirmation requirements. In an agent setting, this can cause unintended disclosure of user content or secrets and trigger real-world actions on external services without adequate user awareness.
