create_webhook

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states the action and event types, omitting side effects such as whether the webhook is immediately active, authentication requirements, or response behavior. For a mutation tool, this is a significant gap.

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, focused sentence that front-loads the verb and resource, includes the relevant event types, and contains no filler words. It is optimally concise.

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?

For a create operation with no output schema and no annotations, the description is sparse. It does not mention what the tool returns (e.g., webhook ID), activation behavior, error conditions, or the meaning of the custom 'PROCESSED' event. This leaves the agent without critical operational context.

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 description coverage is 100%, with all four parameters documented, including enum values for action and diffType. The tool description adds no new semantic information beyond listing the action enum, so it does not enhance what the schema already provides.

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 uses the specific verb 'Register' with the resource 'webhook' and clarifies it is for entity events with enumerated action types (CREATE/UPDATE/DELETE/PROCESSED). This clearly distinguishes it from sibling webhook management tools like list_webhooks, update_webhook, and delete_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 usage for creating a new webhook, and the sibling names (list/update/delete) indicate alternatives, but the description itself does not explicitly state when to use this tool versus those alternatives, nor does it mention prerequisites or use cases. Context is clear but lacks explicit guidance.

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