create-webhook

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

With no annotations provided, the description carries the full behavioral disclosure burden. It usefully discloses that the signing secret is returned only once and that the operation has a webhooks:write scope, but it omits other behavioral details like side effects, idempotency, or response structure beyond the secret.

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 with no filler, front-loading the core action first. The endpoint, one-time secret warning, and scope are all conveyed in a compact structure where every clause earns its place.

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 six parameters, nested objects, no output schema, and no annotations, the description is far too thin. It does not explain the full return value, required parameters, or post-creation behavior, leaving an agent under-equipped to invoke the tool correctly.

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 input schema covers only 50% of parameters with descriptions; filters, isActive, and description are left unexplained. The tool description adds no parameter-level meaning, so an agent cannot determine how filters or isActive should be populated despite the nested object complexity.

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 opens with 'Create a webhook endpoint,' which is a specific verb plus resource and clearly distinguishes this tool from siblings like list-webhooks, get-webhook, update-webhook, and delete-webhook. It also adds the exact POST endpoint and required scope, reinforcing the tool's purpose.

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?

There is no guidance on when to use this tool versus alternatives such as update-webhook or delete-webhook. The description does not state prerequisites, exclusions, or conditions that would help an agent decide between creating a new webhook and modifying an existing one.

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