ebay_get_offer

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

No annotations are present, so the description must fully convey behavioral traits. It only states a read operation, but does not disclose authentication requirements, rate limits, side effects, or what exactly is returned. The lack of detail leaves the agent uninformed about critical behavioral aspects.

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 with no extraneous words. It is appropriately concise, though it could be slightly more informative without losing 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?

For a simple get operation with no output schema, the description should at least hint at the return value (e.g., 'returns offer details'). It fails to do so, leaving the agent without information on what to expect from the tool's output.

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 a single parameter 'offerId' described as 'The offer ID'. The description adds no additional meaning beyond the schema, so it meets the baseline for high coverage but provides no extra value.

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 states 'Get a specific offer by ID', which clearly identifies the action (get) and resource (specific offer). It distinguishes from sibling 'get' tools by specifying 'offer' and 'by ID', though it does not explicitly contrast with similar tools like 'ebay_get_offers'.

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 such as ebay_get_offers for listing multiple offers or ebay_create_offer for creation. The description lacks context for appropriate usage.

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