monitor_payment_status

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

With no annotations, the description carries full burden for behavioral disclosure. It only says 'monitor payment status changes in real-time' without explaining how the monitoring works, whether it blocks, how updates are delivered, or the lifecycle of the monitoring session. This is a significant gap for a real-time tool.

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 a single, clear sentence with no redundancy. It is concise and easy to parse, though it could include more detail without becoming verbose.

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 there is no output schema and no annotations, the description is incomplete. It does not explain what the tool returns, how the webhook and check interval interact, or how to stop monitoring. The agent is left without enough context to invoke it correctly.

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 descriptive parameter comments, so the baseline is 3. The description adds no additional meaning about parameters beyond what the schema already provides, such as the role of webhookUrl or checkInterval.

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 verb 'monitor' clearly indicates ongoing observation of payment status, distinguishing it from one-time retrieval tools like get_payment. The resource is specific ('payment status changes'), but the mechanism (webhook vs polling) is not stated, which leaves some 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 provides no guidance on when to use this tool versus alternatives. It does not mention scenarios such as needing real-time notifications or that get_payment should be used for one-time status checks.

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