ebay_update_notification_config

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

No annotations are provided, so the description must bear the full burden of behavioral disclosure. It only states 'update', which implies mutation, but does not explain consequences, permissions required, or whether the change is immediate or reversible. The description adds minimal transparency beyond the name.

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 extremely concise with no wasted words, but it is under-informative. While brevity is good, it sacrifices clarity and completeness. It is appropriately sized for a simple tool but lacks structure and front-loading of key details.

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 that the tool has only one parameter and no output schema, the description should provide complete context. It does not explain what 'notification configuration' entails, whether the update is additive or replaces existing settings, or any side effects. The agent would have to infer too much.

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 description for the only parameter 'alert_email'. The tool description does not add any additional semantic meaning beyond what the schema already provides. According to calibration, baseline is 3 for high coverage, and the description does not improve it.

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 'Update notification configuration' uses a verb+resource structure, making the basic action clear. However, it is vague and does not distinguish itself from sibling tools like ebay_create_notification_destination or ebay_update_notification_subscription. The input schema reveals it only updates an alert email, so the description could be more specific.

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 prerequisites, when-to-use, or when-not-to-use. Given the large set of sibling tools, this omission reduces usability.

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