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

There are no annotations and the description gives no behavioral information such as read-only nature, output format, or potential side effects. The agent is left to infer from the name that this is a retrieval tool, which is not explicitly disclosed.

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 extremely short and front-loaded, with no wasted words. However, it is a fragment rather than a complete sentence, which slightly undermines its clarity while still being appropriately concise for a simple tool.

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 simple tool with no output schema, the description still fails to explicitly state that the tool retrieves or lists accessories, leaving the agent to infer the action from the name. The list of categories gives some context but not enough to fully understand the tool's invocation and return behavior.

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?

With zero parameters, the schema fully documents the input, and the baseline is 4. The description adds a bit of context by listing the specific types of accessories, but since there are no parameters, no additional parameter meaning is needed.

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 lists accessory categories (technical pits, stands, covers, LagunaBox) which clarify the tool's scope but uses no verb, coming across as a label rather than a statement of function. It is more informative than a pure tautology but still lacks a clear action.

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 on when to use this tool versus alternatives; the description does not mention any conditions, prerequisites, or refer to sibling tools. It simply names accessory types without indicating selection criteria.

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