Get a Boxes object

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the description does not need to restate safety. It adds that the ID is stable and that exactly one record is returned, but it does not describe behavior for missing IDs, error cases, or the return shape. No contradiction with annotations.

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, front-loaded sentence with no filler. Every word contributes to the tool's purpose and key parameter.

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 one-parameter, read-only lookup tool, the description is nearly sufficient. The only notable gaps are no explicit mention of the return value and no guidance on how the stable Boxes MCP ID is obtained, but these are minor for a simple get-by-ID operation.

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 schema only defines an id string with minLength 1, providing no semantic context. The description adds meaningful meaning by identifying the parameter as a stable Boxes MCP ID used to fetch a single inventory record, going beyond the bare 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?

States a specific action ('Get one inventory record') and the distinguishing identifier ('stable Boxes MCP ID'). This clearly separates it from sibling tools like search_inventory, list_contents, and inventory_totals.

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 the tool should be used when the agent already has a stable Boxes MCP ID for a single inventory record. However, it does not explicitly say when not to use it or point to alternatives such as search_inventory when the ID is unknown.

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