Review existing UI code for design system consistency.
AI agents call design_review to retrieve information from SIN-Code-Frontend-Design-Skill without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a read-only review of existing UI code against design system standards. It queries and analyzes code for consistency violations but does not create, modify, delete, or execute any operations. This is a typical Read category tool that has minimal blast radius if misused by an AI agent—it can only surface information about design consistency issues.
From the tool's definition Tool name 'design_review' and description 'Review existing UI code for design system consistency' indicate an inspection/analysis function that retrieves and examines code without modifying it.
Attacks that exploit this kind of access
Review existing UI code for design system consistency. It is categorised as a Read tool in the SIN-Code-Frontend-Design-Skill MCP Server, which means it retrieves data without modifying state.
Register the SIN-Code-Frontend-Design-Skill MCP server in PolicyLayer and add a rule for design_review: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches SIN-Code-Frontend-Design-Skill. Nothing to install.
design_review is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the design_review rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for design_review. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
design_review is provided by the SIN-Code-Frontend-Design-Skill MCP server (opensin-code/sin-code-frontend-design-skill). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
