track_bids

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

The verb 'View' implies a non-mutating operation, but with no annotations, the description carries the full burden of behavioral disclosure. It does not explain whether the response includes live data, pagination, or what 'status' entails (e.g., winning/outbid). Still, the read-only nature is reasonably conveyed.

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, front-loaded sentence with no filler. Every word contributes to the core purpose, making it highly efficient and easy to parse.

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?

For a simple one-parameter tool with no output schema, the description is nearly complete. It states the purpose clearly and implies a read-only operation. Minor gaps include not specifying what 'status' covers or whether the history includes current and past bids, but these are not critical for basic invocation.

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 already has 100% coverage with a clear description for item_id ('eBay auction item ID'). The tool description adds no further parameter detail, so it meets the baseline without adding extra value beyond the schema.

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 uses a specific verb ('View') and clearly identifies the resource ('bid history and status') and scope ('eBay auction item'). It is easily distinguishable from sibling tools such as place_bid (action) and get_item_details (item details), which focus on different aspects.

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. It does not mention that it is read-only or suggest it for tracking bid activity before placing a bid. There is no explicit 'when-not-to-use' or comparison with sibling tools.

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