Why spec_coding_design_confirmed needs a policy

This tool confirms a design document and advances the workflow to the next stage (task planning). It writes/updates workflow state by marking the design phase as complete. No code is executed, no data is deleted, and no financial transactions occur. The blast radius is low since it's a workflow state transition within a spec-driven development process.

From the tool's definition Confirm the completion of the design document and proceed to the task planning phase

POLICY

How to control spec_coding_design_confirmed

PolicyLayer is an MCP gateway — it sits between your AI agents and Spec-driven Development MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for spec_coding_design_confirmed:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "spec_coding_design_confirmed": {
      "limits": [
        {
          "counter": "spec_coding_design_confirmed_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

spec_coding_design_confirmed stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about spec_coding_design_confirmed

What does the spec_coding_design_confirmed tool do? +

Confirm the completion of the design document and proceed to the task planning phase. It is categorised as a Write tool in the Spec-driven Development MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on spec_coding_design_confirmed? +

Register the Spec-driven Development MCP Server MCP server in PolicyLayer and add a rule for spec_coding_design_confirmed: 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 Spec-driven Development MCP Server. Nothing to install.

What risk level is spec_coding_design_confirmed? +

spec_coding_design_confirmed is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit spec_coding_design_confirmed? +

Yes. Add a rate_limit block to the spec_coding_design_confirmed 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.

How do I block spec_coding_design_confirmed completely? +

Set action: deny in the PolicyLayer policy for spec_coding_design_confirmed. 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.

What MCP server provides spec_coding_design_confirmed? +

spec_coding_design_confirmed is provided by the Spec-driven Development MCP Server MCP server (kevinlin/spec-coding-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Spec-driven Development MCP Server tool call.

Start from Spec-driven Development MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
