ebay_fetch_payment_dispute_evidence_content

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

No annotations are provided, so the description must carry the burden of behavioral transparency. It only says 'Download evidence file content' without disclosing traits such as file size limits, content format (binary vs. URL), or whether the download is idempotent. The OAuth scope is auth, not behavior.

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 short (two sentences) and front-loaded with the action. The second sentence conveys necessary auth information. However, it is minimal and lacks some important details, but no word is wasted.

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 3-parameter tool with no output schema and no annotations, the description is incomplete. It does not explain how to obtain the required IDs (evidenceId, fileId) from related tools, nor does it describe the format or size of the downloaded content, leaving significant gaps for correct 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?

Schema coverage is 100%, so the schema already describes each parameter. The description adds no additional meaning beyond the parameter names and types. Baseline of 3 applies, as no extra context is provided.

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 'Download evidence file content from a payment dispute', using a specific verb and resource. It uniquely identifies the tool among siblings like ebay_upload_payment_dispute_evidence_file and ebay_get_payment_dispute_activities, with no ambiguity.

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 required OAuth scopes but provides no guidance on when to use this tool versus alternatives, prerequisites (e.g., obtaining evidenceId and fileId from other endpoints), or context for invocation.

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