ebay_get_notification_subscriptions

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

No annotations provided, so the description carries the full burden. It only mentions pagination but does not disclose authentication needs, rate limits, response format, or what 'subscriptions' entails (e.g., topics, filters). The description is too sparse for a read operation.

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 exceptionally concise (one phrase) and front-loaded with the main action. However, it is almost too brief; a sentence structure would be clearer. Still, it earns a 4 for efficiency.

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?

No output schema exists, so the description should explain the return value. It does not mention what data is returned (e.g., list of subscription IDs, details). As a paginated retrieval tool, it lacks essential context about response structure.

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% with clear descriptions for both parameters ('Maximum number of subscriptions to return' and 'Token for pagination'). The description adds no additional meaning beyond the schema, which is adequate given high coverage.

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 all notification subscriptions (paginated)', which clearly indicates the tool retrieves multiple subscriptions with pagination. It distinguishes from sibling ebay_get_notification_subscription (singular) by specifying 'all' and 'paginated', but could be more explicit like 'List all notification subscriptions'.

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. Siblings like ebay_get_notification_subscription and ebay_create_notification_subscription exist, but the description does not provide context for selection or exclusions.

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