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 that it registers a webhook and lists parameters. It does not disclose behavioral traits such as idempotency, error handling, rate limits, or that the webhook will begin delivering immediately. The description is minimal and fails to inform the agent of important behaviors.

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 concise, front-loaded with purpose, and uses a clear list for parameters. Every sentence adds value without redundancy. It efficiently communicates the essential information.

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 3 parameters and no output schema, the description should explain the return value (e.g., created webhook object) or confirmation behavior. It does not. It also lacks information about validation, idempotency, or whether the webhook is immediately active. The description is incomplete for an agent to fully understand the tool's effects.

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?

With 0% schema description coverage, the description adds significant meaning beyond the input schema. It specifies that endpoint is an 'HTTPS URL to receive POSTs', event_types are enumerated with exact values, and description is an 'optional label'. This helps the agent understand parameter constraints and expectations.

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 clearly states the tool's purpose: 'Register a webhook to drive automations' and provides concrete examples (feed bookings/forms into CRM, email drafts). It effectively distinguishes itself from sibling tools like delete_webhook, update_webhook, and list_webhooks by specifying the creation action.

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 webhooks but does not explicitly state when to use this tool versus alternatives. It lacks guidance on prerequisites, such as needing a valid endpoint or that event_types must match predefined values. No exclusions or when-not scenarios are mentioned.

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