Extract design tokens from existing code.
AI agents call design_token_extract 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.
This tool reads and extracts design tokens (variables, colors, spacing, typography settings, etc.) from existing code. It performs analysis and retrieval with no side effects—no data is created, modified, deleted, or any external operations are triggered. This is a clear Read category action.
From the tool's definition Tool name 'design_token_extract' and description 'Extract design tokens from existing code' indicate retrieval and analysis of data without modification.
Attacks that exploit this kind of access
Extract design tokens from existing code. 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_token_extract: 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_token_extract 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_token_extract 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_token_extract. 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_token_extract 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.
