ebay_bulk_confirm_packages

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

No annotations are provided, so the description must fully cover behavioral traits. It only states a vague 'confirm' without explaining side effects, state changes, authentication needs, or limitations. For a mutation tool, this is insufficient.

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 one short sentence, which is concise but sacrifices necessary detail. It fails to earn its place by omitting critical information about the tool's usage.

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 complex input schema with no parameter descriptions, no output schema, and the tool being a bulk mutation, the description is severely incomplete. It does not enable an agent to use the tool effectively.

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 only parameter 'body' is a free-form object with schema coverage 0%. The description offers no hint about its expected structure, required fields, or format. The agent has no guidance on constructing a valid request.

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 clearly states the action ('Confirm'), the resource ('multiple packages'), and the scope ('in one request'), effectively distinguishing it from the single-package sibling 'ebay_confirm_package'.

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 on when to use this bulk version versus the single-package tool, no prerequisites or conditions mentioned. The description only implies usage through the name and bulk indication.

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