Get Rack Storage Item

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

ReadOnlyHint, idempotentHint, and destructiveHint are already in annotations. The description adds useful behavioral context about non-guessable ids and the ambiguous 404, which is beyond the annotations. 'Operation class: Read' merely restates annotations, offering no extra disclosure.

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 concise and front-loaded, with each sentence serving a purpose. The definitional second sentence and the list-first guidance both aid understanding; only the 'Operation class: Read.' line is slightly redundant with annotations.

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 get-by-id tool with 2 parameters and no output schema, the description covers the core operation, defines the resource, and includes error ambiguity. It doesn't describe the return value, but that's implicitly the requested item and the schema's response_format param covers output shape.

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%, so parameters are fully described in the schema. The description echoes that id is numeric but doesn't add new parameter semantics beyond the schema's own descriptions.

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 opens with 'Fetch one rack storage item by its numeric id,' a specific verb-resource pair. It further distinguishes rack storage items from the rack storage cabinet, referencing hudu_*_rack_storage tools, which differentiates this from sibling tools like hudu_get_rack_storage.

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?

It explicitly instructs to use hudu_list_rack_storage_items first when only a name is known, explains ids are not guessable, and notes the identical 404 response, setting clear expectations for when this tool should and shouldn't be used.

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