ebay_send_offer_to_interested_buyers

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

No annotations are present, so the description must fully disclose behavior. It only says 'send offer', with no mention of side effects, authentication needs, rate limits, or restrictions (e.g., offer duration limited to 2 days, only one item allowed). 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 only one sentence, which is concise but severely under-specified for a tool with 5 parameters, nested objects, and no output schema. It sacrifices completeness for brevity.

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's complexity (5 parameters, nested objects, no annotations, no output schema), the description is woefully incomplete. It does not mention required permissions, what happens on success/failure, the list of buyers targeted, or any constraints.

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?

Input schema coverage is 100%, so each parameter is described in the schema. The description adds no additional meaning beyond what the schema provides. Baseline score 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 'Send offer to interested buyers' clearly states the verb and resource, but does not differentiate it from sibling tools like ebay_create_offer or ebay_bulk_create_offer, which also involve sending offers. It lacks specificity about what 'interested buyers' means (e.g., watchers or previous buyers).

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 is provided on when to use this tool versus alternatives. Given the many sibling tools for offers, the agent needs context on prerequisites (e.g., listing must have interested buyers) and when not to use it.

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