test_webhook

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

With no annotations, the description carries the full burden for behavioral disclosure. It states the action ('send a synchronous test delivery') and the return behavior ('return the endpoint's live result'). This covers the core behavior. It does not mention potential side effects like triggering integrations, but for a test action this is likely acceptable. The description is transparent about synchronicity and the returned live result, which is strong for a simple one-parameter tool.

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 a single, concise sentence that front-loads the action ('Send a synchronous test delivery') and includes the HTTP route, which adds useful context without bloat. Every word earns its place, and it's easy to scan.

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 tool has only one parameter and no output schema, the description adequately covers essentials: what it does (send test) and what it returns (live result). It could specifiy the return format (e.g., status code, body) but for a webhook test the phrase 'live result' is likely sufficient. The description is complete enough for an agent to call 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 coverage is 100%, with the parameter 'id' described as 'The webhook id.' The description does not add any additional meaning beyond the schema, which is fine because the schema already suffices. Baseline 3 is appropriate since the description doesn't enhance parameter understanding but also doesn't need to.

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 verb ('Send'), resource ('endpoint'), and action ('synchronous test delivery'), and includes the HTTP method/path (POST /webhooks/:id/test). This clearly distinguishes it from sibling webhook tools like get_webhook (retrieves config) or delete_webhook (removes), leaving no ambiguity about its 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?

The description clearly implies when to use: when you need to send a test webhook and get its live result. No explicit exclusion of alternatives, but there is no other sibling that performs this action. The context is clear, and the description includes the synchronous nature, which helps set expectations. A minor gap is not explicitly stating that this actually triggers an event to the endpoint, though that is implied by 'test delivery'.

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