slack-automation

The skill is a legitimate Slack automation guide that delegates all Slack interactions and OAuth lifecycle to a third-party MCP (https://rube.app/mcp). There is no explicit malicious code in the provided file (no reverse shells, no hard-coded credentials, no obfuscation in the text). The primary security concern is the brokered trust model: OAuth tokens and all message/metadata transit through and are likely stored by the MCP operator, which creates a credential-forwarding / man-in-the-middle risk. Recommend vetting rube.app's security and privacy controls, favoring direct integrations when possible, applying least-privilege scopes, and auditing MCP activity before using in sensitive workspaces.
