get_store_status

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

With no annotations, the description carries the burden of behavioral disclosure. It reveals the return values (open/busy) and implies a read-only operation via 'Get', but does not detail error behavior, freshness, or other characteristics. It is minimally transparent but not misleading.

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 one sentence, front-loaded with the action and resource, and includes the essential output hint. Every word earns its place; it is appropriately sized for the tool's simplicity.

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?

For a parameterless tool with no output schema and no annotations, the description sufficiently covers the return values (open/busy). Given the low complexity, no additional information is necessary to select or invoke the tool correctly.

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 schema is empty. Per rubric, 0 params receives a baseline of 4. The description does not need to explain nonexistent parameters, and it adds value by clarifying the output values.

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 'Get current store status (open/busy)' uses a specific verb ('Get') and clearly identifies the resource ('store status') with the possible values parenthetically. This distinguishes it from sibling tools, which are all order/product related.

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 usage: when you need to know if the store is open or busy. However, it does not explicitly state when to use it versus alternatives, and there are no exclusions or scenarios provided. This is sufficient for a simple getter but lacks explicit guidance.

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