Generates a domain-specific quality checklist (security, accessibility, performance, etc.) by analyzing SPECIFICATION.md and DESIGN.md. Writes CHECKLIST.md.
AI agents use sdd_checklist to create or update resources in Specky — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Specky environment.
sdd_checklist creates a new markdown file (CHECKLIST.md) based on analysis of existing specifications and designs. This is a reversible write operation with no side effects beyond file creation. The generated checklist is informational output used for quality assurance purposes, not an executable command or destructive operation.
From the tool's definition Tool description states it 'Writes CHECKLIST.md' - a file creation/modification action. The verb 'Generates' and the output artifact indicate content creation rather than mere data retrieval.
Documented attack patterns abuse exactly the kind of access sdd_checklist gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Specky, and nothing reaches the server without passing your rules. This is the rule we recommend for sdd_checklist:
{
"version": "1",
"default": "deny",
"tools": {
"sdd_checklist": {
"limits": [
{
"counter": "sdd_checklist_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}sdd_checklist 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.

Generates a domain-specific quality checklist (security, accessibility, performance, etc.) by analyzing SPECIFICATION.md and DESIGN.md. Writes CHECKLIST.md. It is categorised as a Write tool in the Specky MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Specky MCP server in PolicyLayer and add a rule for sdd_checklist: 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 Specky. Nothing to install.
sdd_checklist is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the sdd_checklist 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 sdd_checklist. 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.
sdd_checklist is provided by the Specky MCP server (paulasilvatech/specky). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Specky, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
