Implementation Reference

  • The tool 'system_nodes_statistics' is registered in the server using server.tool. It calls the 'client.getNodesStatistics()' method.
    server.tool(
        'system_nodes_statistics',
        'Get node statistics',
        {},
        async () => {
            try {
                const result = await client.getNodesStatistics();
                return toolResult(result);
            } catch (e) {
                return toolError(e);
            }
        },
    );
  • The handler implementation in the client calls the REST API endpoint defined as REST_API.SYSTEM.STATS.NODES_STATS.
    async getNodesStatistics() {
        return this.get(REST_API.SYSTEM.STATS.NODES_STATS);
    }
Behavior2/5

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

With no annotations, the description carries full burden but only states the action without disclosing behavioral traits like read-only status, potential side effects, rate limits, or authentication needs. It's minimal and doesn't add meaningful context beyond the basic action.

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

Conciseness4/5

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

The description is a single, efficient sentence with no wasted words, making it appropriately concise. However, it could be more structured by front-loading key details, but its brevity is a strength in this context.

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

Completeness2/5

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

Given the complexity implied by 'statistics' and the lack of annotations and output schema, the description is incomplete. It doesn't explain what statistics are returned, their format, or any limitations, leaving significant gaps for the agent to understand the tool's behavior.

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

Parameters4/5

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

The tool has 0 parameters with 100% schema description coverage, so no parameter information is needed. The description doesn't add semantics beyond the schema, but this is acceptable given the lack of parameters, aligning with the baseline for zero parameters.

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

Purpose3/5

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

The description 'Get node statistics' clearly states the action (get) and resource (node statistics), but it's vague about what 'node statistics' entails and doesn't differentiate from sibling tools like 'system_nodes_metrics' or 'system_stats'. It provides basic purpose but lacks specificity.

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

Usage Guidelines2/5

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

No guidance is provided on when to use this tool versus alternatives such as 'system_nodes_metrics' or 'system_stats'. The description offers no context, prerequisites, or exclusions, leaving the agent to 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.
