ebay_update_notification_config

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

With no annotations provided, the description must disclose behavior. It only says 'Update', implying mutation, but does not explain whether the update merges with existing settings or replaces them, what permissions are needed, or any side effects. The optional single parameter is noted in the schema but the description adds no behavioral context.

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 concise (one sentence) and front-loaded with the action. It is efficient but lacks structure or additional contextual sentences. Every word earns its place given the simple tool, though it could benefit from more detail.

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 tool performs a mutation (update) with one optional parameter, no output schema, and no annotations, the description is incomplete. It does not explain what 'notification configuration' comprises, whether other config aspects exist, or what the response looks like. The sibling list is extensive but not leveraged for disambiguation.

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% (1 parameter described). The description adds no additional information about the parameter beyond what the schema provides (alertEmail for alerts). Since the schema already documents the parameter, the description meets the baseline but does not enhance understanding.

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' clearly states the verb ('Update') and resource ('notification configuration'). It accurately reflects the tool's function but does not differentiate it from sibling tools like ebay_get_notification_config or ebay_update_notification_destination, which are distinct actions.

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 usage guidance is provided. The description does not mention when to use this tool versus alternatives (e.g., when to update vs get config, or context for updating notification configurations). There is no indication of prerequisites or typical scenarios.

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