ebay_fetch_payment_dispute_evidence_content

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

No annotations are present, so the description carries full burden. It states the action and scope but does not disclose behavior like error cases, file size limits, or that it returns raw file content (binary). The description is too minimal for full transparency.

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 very short (two sentences plus scope), front-loaded with the main action. Every sentence is necessary, though it could be better structured with clearer usage context.

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 simple nature of the tool (file download with 3 required params), the description lacks workflow context, such as the need to fetch evidence IDs via 'get_payment_dispute' first. No output schema means return format is unspecified.

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?

Schema coverage is 100%, so all parameters are described in the schema. The description adds no additional meaning beyond what the property descriptions already provide (e.g., 'the file ID to download'). 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 clearly states the action ('Download evidence file content') and the resource ('from a payment dispute'). It is specific and distinguishable from siblings like 'upload_payment_dispute_evidence_file' or 'get_payment_dispute', though it does not explicitly differentiate.

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 only mentions the required OAuth scope. It provides no guidance on when to use this tool versus alternatives (e.g., when you need to view evidence vs. upload it), nor any prerequisites or exclusions.

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