create_webhook

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

With no annotations, the description carries full burden. It discloses that the webhook will POST to an HTTPS endpoint and returns the webhook with id and signing secret. However, it omits details about permissions, validation, or failure modes, which would improve transparency. Overall adequate but not detailed.

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 concise sentences. The first sentence states the core action and scoping options; the second mentions the return value. No redundant information, well front-loaded, and every word contributes.

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 no output schema, the description covers the return value. It addresses the key parameters (required endpoint and events, optional scopes) and their aggregate behavior. Missing error handling or prerequisites, but for a create tool with many optional params, it is reasonably complete.

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%, so baseline is 3. The description adds value by explaining scoping behavior ('omit all scopes to watch the whole Workspace') and that the return includes a signing secret. This goes beyond the individual parameter 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 the tool's purpose: creating a webhook that POSTs event payloads. It specifies the resource (webhook) and action (create), and distinguishes from siblings like update_webhook or delete_webhook by focusing on creation and mentioning optional scoping.

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 guidance on when to use scoping options ('optionally scope it to a single space, folder, list or task; omit all scopes to watch the whole Workspace'). It does not explicitly contrast with alternatives like create_task or other creation tools, but for a webhook creation tool, this is sufficient context.

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