ebay_bulk_create_or_replace_inventory_item

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

With no annotations, the description must disclose behavioral traits. It fails to mention side effects, idempotency ('replace' vs 'update'), permissions, error handling, or response behavior. The term 'replace' is ambiguous without further explanation.

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, clear sentence front-loaded with the action and object. No word is wasted, but it could incorporate additional context without becoming verbose.

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 complexity of nested objects in the schema, no output schema, and no annotations, the description is too minimal. It does not explain the effect of 'replace', required fields, or what happens on partial success/failure, leaving the agent underinformed.

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% with the requests parameter described as 'Bulk inventory item requests', but the description adds no semantic value beyond the schema, which already details the nested structure. Baseline of 3 is appropriate.

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 specifies the verb 'Bulk create or replace' and the resource 'inventory items', clearly distinguishing it from single-item tools like ebay_create_inventory_item and read tools like ebay_bulk_get_inventory_item.

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 bulk vs single but provides no explicit guidance on when to use this tool over alternative bulk tools (e.g., ebay_bulk_update_price_quantity) or what prerequisites are needed.

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