Create Webhook

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

Annotations are minimal (readOnlyHint=false, idempotentHint=false, destructiveHint=false). The description adds context by listing events and mentioning a signing secret, but does not disclose potential side effects (e.g., URL validation, test notification sent), rate limits, or authentication requirements. The description does not contradict annotations.

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 and includes an example, but is repeated in both English and Spanish, doubling length without adding value. The structure is front-loaded with the main verb and resource, but the bilingual repetition is not efficient.

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 presence of an output schema (not shown), the description does not need to explain return values. It covers the main functionality, required parameters, and available events. It lacks mention of permissions or URL accessibility requirements, but overall is sufficiently complete for a webhook creation tool.

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%, so baseline is 3. The description adds value by listing all available events and showing an example with url, events, and secret. It also implies the active parameter defaults to true (schema confirms). This goes beyond the schema's basic descriptions.

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 'Register a new webhook endpoint' with specific verb ('register') and resource ('webhook endpoint'). It lists available events and provides an example, distinguishing it from sibling tools like get_webhook, update_webhook, delete_webhook, test_webhook, list_webhooks.

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 explains what to specify (URL, events, secret) and provides a list of available events. It gives an example usage. However, it does not explicitly state when to use this tool versus alternatives (e.g., update_webhook), nor does it mention prerequisites or context for use.

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