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

With no annotations provided, the description carries full burden for behavioral disclosure. It mentions what the tool does but doesn't describe important behavioral traits like whether this is a read-only operation, potential rate limits, authentication requirements, or what happens when no stores are found. The description is minimal and lacks operational context.

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 appropriately concise with two sentences that directly state the purpose and provide parameter context. The structure with a clear purpose statement followed by Args section is well-organized. However, the 'Args' section references a parameter that doesn't exist in the schema, which creates some confusion.

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 the tool has 0 parameters, 100% schema coverage, and an output schema exists, the description is reasonably complete for its simple purpose. However, the mismatch between the description mentioning 'merchantID' and the schema having no parameters creates confusion. For a tool with sibling alternatives, more differentiation would be beneficial.

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 has 0 parameters with 100% coverage, so no parameter documentation is needed. The description mentions 'merchantID: string' in the Args section, which adds context about what information might be relevant, even though it's not a formal parameter. This provides helpful semantic context beyond the empty 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 states the tool's purpose as 'Find all stores under a merchantID class', which is a clear verb+resource combination. However, it doesn't distinguish this tool from its sibling 'findStore', making the scope somewhat vague. The mention of 'merchantID class' adds specificity but the relationship to sibling tools is unclear.

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 is provided about when to use this tool versus alternatives like 'findStore'. The description implies usage for retrieving all stores associated with a merchantID, but there's no explicit comparison with sibling tools or context about when this is preferred over more specific searches.

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