Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full responsibility. It clearly implies a read-only listing operation and usefully scopes to 'optional upstream' servers. However, it does not mention details such as what data is returned, whether the list is filtered by enabled status, or any auth/config dependencies. For a zero-parameter list this is a minor gap, so it remains adequate.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence that front-loads the verb and resource. Every word earns its place and there is no redundancy or unnecessary detail.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With zero parameters and an output schema present, the description is functionally sufficient for an agent to invoke the tool. It states the operation and scope. The main missing element is sibling differentiation, but that does not prevent correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema is empty and there are zero parameters. The baseline for zero-parameter tools is 4 because there is nothing the description needs to explain about parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb 'List' with a clear resource: 'optional upstream MCP servers configured for this Security Recipes server.' It conveys the operation and scope well, but it does not explicitly differentiate itself from sibling tools like recipes_mcp_servers_list or recipes_mcp_upstream_tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives such as recipes_mcp_servers_list or recipes_mcp_upstream_call. There is no context about selection criteria, exclusions, or prerequisites, so the agent must infer usage from the name alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
