c-slack

The skill's stated purpose (sending Slack messages and uploading files via a CLI) is coherent with its described capabilities. Core concerns center on credential handling, trusted sources for the cli tool, and explicit guidance on secure token management. As implemented, the data flow is standard for Slack integrations, but the absence of verifiable install/source details and explicit secure credential handling elevates risk to MEDIUM. Provision more detail on installation provenance, credential input methods, and secure storage/rotation to improve security posture.
