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

Annotations already disclose destructive and idempotent behavior, so the description does not need to repeat those. It adds 'by ID' and the DELETE endpoint mapping, which is useful but does not reveal additional consequences like permanence or side effects beyond what annotations provide.

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 two short sentences, front-loaded with the core action, and includes a useful API reference without redundancy. Excellent conciseness.

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?

With the output schema present, annotations covering destructiveness/idempotency, and a clear parameter schema, the description is largely complete for a simple delete operation. It could mention permanence or downstream effects, but nothing essential is missing.

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 schema covers 100% of the parameters with clear descriptionsyk. The description adds no extra parameter semantics beyond confirming that the removal is by ID.

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 a specific action ('Remove a business outbound webhook by ID') and reinforces it with the HTTP DELETE mapping. This makes the tool’s purpose unmistakable and distinguishes it from set_webhook and get_webhook.

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 implies when to use the tool (when removing a webhook by ID), but it does not explicitly state when not to use it or contrast it with alternatives like set_webhook. The guidance is adequate but not explicit.

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