Security Findings1

Severity	Finding	Layer	Location
MEDIUM	Skill enables broad Slack workspace access The `slack-automation` skill, as described in `SKILL.md`, provides access to a wide range of Slack operations including sending, editing, and searching messages, listing all channels and users, managing reactions, and scheduling messages. This comprehensive toolset implies that the underlying Slack integration (via Rube MCP) would require extensive OAuth scopes (e.g., `chat:write`, `channels:read`, `users:read`, `search:read`, `reactions:write`, `im:write`, `mpim:write`, `groups:read`, `team:read`, `chat:schedule`). While necessary for full automation, such broad access, if granted to an AI agent without strict controls, could lead to significant data exposure, unauthorized communication, or manipulation of the Slack workspace. Review the necessity of each Slack tool for the agent's specific tasks. Implement granular OAuth scopes where possible, granting only the minimum required permissions. Ensure the agent's operational context includes robust guardrails and human oversight for sensitive Slack operations. Consider breaking down the skill into smaller, more specialized skills with narrower permission sets.	LLM	SKILL.md:29
