Security Findings2

Severity	Finding	Layer	Location
MEDIUM	Unpinned Rube MCP dependency The skill manifest specifies a dependency on 'rube' for the MCP without a version constraint. This allows any version of 'rube' to be used, including potentially malicious future versions, introducing a supply chain risk. It is recommended to pin dependencies to specific versions or version ranges to ensure stability and security. Pin the 'rube' dependency to a specific version or version range (e.g., `{"mcp": ["rube==1.2.3"]}` or `{"mcp": ["rube>=1.0.0,<2.0.0"]}`) in the skill manifest.	Static	Manifest
LOW	Exposure of RUBE_REMOTE_WORKBENCH for arbitrary tool execution The skill documentation highlights the use of `RUBE_REMOTE_WORKBENCH` with `run_composio_tool()`. This tool provides a broad capability to execute arbitrary Composio tools. While intended functionality, this represents a powerful interface that, if misused by an agent or if the underlying tools are compromised, could lead to excessive permissions or unintended actions. It grants a wide scope of tool access. Advise agents to exercise extreme caution when using `RUBE_REMOTE_WORKBENCH` and to validate all inputs and outputs. Ensure that the underlying `composio_tool()` calls are strictly controlled and audited. Consider if such a broad tool is strictly necessary for the skill's primary function, or if more granular tool access could be provided.	Static	SKILL.md:80
