ebay_update_inventory_location

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

With no annotations provided, the description must disclose behavioral traits. It only states 'Update an inventory location', implying mutation but giving no details about side effects, required permissions, reversibility, or what happens to existing settings. The agent is left guessing about the tool's behavior beyond the surface level.

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?

At four words, the description is extremely concise but under-specifies, lacking any structure or additional informative content. Conciseness should not come at the cost of completeness; here, the description is too brief to be useful.

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 the tool has 2 required parameters (one of which is a complex 'body' object), no output schema, and no annotations, the description is incomplete. It fails to explain what fields can be updated, the format of the body, or any response behavior, leaving significant gaps for the agent.

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?

While schema coverage is 100%, the parameter descriptions are minimal: 'The merchant location key' and 'Generated InventoryLocation request body'. The description adds no additional meaning beyond the schema's own minimal text, and the body parameter remains opaque without specification of its structure or required fields.

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 'Update an inventory location' clearly states the verb 'Update' and the resource 'inventory location', making the core purpose immediately understandable. However, it does not differentiate from sibling tools like ebay_create_inventory_location or ebay_enable_inventory_location, which could cause confusion.

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 provides no guidance on when to use this tool versus alternatives, nor does it mention prerequisites, typical use cases, or situations where it should not be used. The agent has no information to decide between update, create, enable, or disable inventory location tools.

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