SkillShield's automated analysis identified 2 findings: 0 critical, 0 high, 1 medium, and 1 low severity. Key findings include Unpinned MCP Dependency, Broad Tool Execution Capability via Rube MCP.
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. All layers scored 70 or above, reflecting consistent security practices.
Last analyzed on February 17, 2026 (commit 99e2a295). SkillShield performs automated 4-layer security analysis on AI skills and MCP servers.
Layer Breakdown
Behavioral Risk Signals
Security Findings2
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| MEDIUM | Unpinned MCP Dependency The skill's manifest specifies a dependency on the 'rube' MCP without a version constraint. This means the skill will always use the latest version of the Rube MCP. If a breaking change or a malicious update is introduced in a new version of 'rube', it could negatively impact the skill's functionality or security without explicit review or consent. Pin the 'rube' MCP dependency to a specific, known-good version (e.g., `"rube@1.2.3"`) to ensure stability and prevent unexpected behavior from future updates. Regularly review and update the pinned version. | Static | Manifest:1 | |
| LOW | Broad Tool Execution Capability via Rube MCP The skill provides access to `RUBE_MULTI_EXECUTE_TOOL` and `RUBE_REMOTE_WORKBENCH` which allow the agent to execute arbitrary operations provided by the `shorten_rest` toolkit. While this is the intended functionality of an automation skill, the `RUBE_REMOTE_WORKBENCH` specifically mentions 'bulk ops' and `run_composio_tool()`, implying a very broad and flexible execution capability. The actual scope of operations available through the `shorten_rest` toolkit is not defined within this skill's context. If the underlying `shorten_rest` toolkit has sensitive or destructive operations, an agent could be prompted to execute them. Ensure that the `shorten_rest` toolkit itself adheres to the principle of least privilege and that its exposed operations are carefully scoped. Implement robust access controls and monitoring for the Rube MCP and its connected toolkits. The skill's documentation could also include warnings about the power of these tools and best practices for their use. | Static | SKILL.md:64 |
