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

No annotations and the description provides no behavioral details. It does not disclose what side effects occur (e.g., whether it modifies listings, sends notifications, requires permissions), leaving the agent without critical operational context.

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 concise sentence, which is efficient for a simple action. However, it lacks any structural elements like examples or sections that could enhance usability.

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 absence of annotations and output schema, the description is insufficient. It does not explain the required preconditions (e.g., existence of interested buyers), error scenarios, or the expected outcome, making it incomplete for an agent to reliably invoke.

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 input schema has 100% coverage with descriptions for all 5 parameters, so the schema itself carries the semantic weight. The tool description adds no additional meaning beyond what the schema provides.

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 ('send offer') and target ('interested buyers'), making the purpose immediately understandable. It distinguishes itself from sibling tools like 'create_offer' or 'update_offer' by specifying the audience, though it could be more specific about the context.

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 tool versus alternatives like 'ebay_create_offer' or 'ebay_update_offer'. The description lacks any context about prerequisites, when to use it, or when not to use it, leaving the agent to infer usage.

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