Security Findings2

Severity	Finding	Layer	Location
MEDIUM	Unpinned MCP dependency The skill manifest specifies a dependency on the 'rube' MCP without a version constraint. This means the skill will always use the latest version of 'rube'. If a future version of 'rube' introduces breaking changes, vulnerabilities, or malicious code, the skill could be compromised without explicit user action. This poses a supply chain risk. Pin the 'rube' MCP dependency to a specific, known-good version (e.g., `"rube": ["rube@1.2.3"]`) to ensure stability and security. Regularly review and update the pinned version.	LLM	SKILL.md:2
LOW	Comprehensive Google Sheets access The skill provides access to a wide range of Google Sheets operations, including reading, writing, creating, deleting, formatting, and managing spreadsheets and tabs. While this is the intended functionality of the skill, users should be aware that granting this skill access effectively grants the LLM comprehensive control over their Google Sheets data and structure. This represents a significant privilege level. Ensure that the LLM's access to this skill is carefully controlled and that users understand the full scope of Google Sheets permissions being granted. Implement least privilege principles where possible, for example, by using dedicated service accounts with restricted access if the underlying MCP supports it.	LLM	SKILL.md:1
