Batch Check SNS Domains

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the description's 'check availability' aligns. However, description does not add additional behavioral context beyond the batch limit, such as rate limits, error handling, or what happens on partial failures. With annotations covering safety, a 3 is appropriate.

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 with 17 words, front-loaded with the main purpose. Every word adds value; no unnecessary details. Highly efficient.

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 that output schema exists (covering return values), annotations handle safety, and parameters are fully described, the description is mostly complete. It includes the batch size limit. The only minor gap is lack of mention of error handling or partial results, but that is minor given the tool's simplicity.

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?

Schema coverage is 100% and the parameter description in the schema already explains the domains array (1-25 .sol domains). The tool description adds no new information about parameters beyond what the schema provides. Baseline 3 is correct.

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 action (check availability), the resource (multiple .sol domains), and includes a specific limit (up to 25). It also mentions the SDK module. Differentiates from sibling tool sap_sns_check_domain by indicating batch operation.

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 implies use for batch checking, but does not explicitly state when to use this tool vs alternatives like sap_sns_check_domain. No guidance on when not to use or prerequisites. The batch nature is clear but lacks contrast guidance.

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