get_cluster_stats

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

With no annotations provided, the description carries full burden for behavioral transparency. It only states that statistics are retrieved, implying a read-only operation, but lacks details on permissions, rate limits, or any side effects. The description is too sparse to inform safe usage.

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 sentence, which is concise, but it is also vague and does not provide enough detail. It states the purpose but lacks important context, making it less effective than a slightly longer but more informative description.

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?

Given the complexity of the domain (multiple sibling tools, required parameters) and the lack of parameter descriptions, the description is incomplete. It does not clarify how to use the parameters or what output to expect, even though an output schema exists.

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?

Input schema has three required parameters (domain, region, profile) with 0% coverage (no descriptions). The tool description does not explain what these parameters represent or how they are used, providing no additional meaning beyond the schema.

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 clearly states the tool retrieves high-level statistics for cluster, node, shard, document, and storage. The verb 'Get' and resource are specific. However, it does not distinguish from sibling tools like get_cluster_health or get_cluster_settings, which are similar in scope.

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?

No guidance on when to use this tool versus alternatives. The description does not include any when-to-use or when-not-to-use context, leaving the agent to infer based on name alone.

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