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

Annotations already declare readOnlyHint=true and idempotentHint=false, so the safety profile is partly covered. The description adds useful detail about returned fields (addresses and public keys) and the Midgard source, but it does not explain why the operation is non-idempotent or what form the returned node data takes.

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 definition is a single front-loaded sentence with no filler. It communicates the tool's action and data source efficiently.

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 no parameters, no output schema, and annotations covering core safety hints, the description is nearly complete. It explains the Midgard source and key returned fields, though it could do more to distinguish this tool from sibling node-information tools.

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 tool has zero parameters, so the baseline is 4. The description does not need to explain parameter meanings and appropriately focuses on the returned data instead.

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 states a specific verb and resource: it returns node information, including addresses and public keys, from Midgard analytics. This is clear enough to understand the tool, but it does not differentiate the tool from siblings such as list_nodes, get_node, or get_cosmos_node_info.

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 phrase 'from Midgard analytics' implies that this tool should be used when Midgard-sourced node data is desired, but there is no explicit guidance on when to use it instead of related node or analytics tools. The usage context is only implied.

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