kaiten_create_webhook

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

No annotations are present, so the description carries the burden of behavioral disclosure. It does disclose important constraints: creation limit, URL length, and the paid-feature requirement. However, it does not explain what happens if a webhook already exists, whether special permissions are required, or what the tool returns, leaving some behavioral gaps.

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 sentences with no fluff. It front-loads the purpose and then states the key constraints concisely, every sentence adds useful 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?

For a simple two-parameter creation tool, the description covers the main invocation concerns: scope, usage limit, and feature requirement. It is slightly incomplete because there is no output schema and the description does not specify the return value or behavior on duplicate creation, but these are minor for calling 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?

Schema description coverage is 100%, and both parameters have meaningful descriptions already. The tool description restates the URL max length but adds essentially no new meaning beyond the schema for either parameter.

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 states a specific action ('Create an external webhook') and resource ('for a Kaiten space'), and the parenthetical 'outbound event notification'clarifies its purpose. The term 'external'explicitly distinguishes it from sibling webhook tools such as kaiten_create_incoming_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?

It provides clear contextual guidance by stating 'Only 1 per space allowed' and 'Requires webhooks paid feature,' which signal when this tool can and cannot be used. It does not explicitly name sibling alternatives like kaiten_list_webhooks or kaiten_update_webhook, but the constraints give an agent enough to decide whether creation is appropriate.

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