Contract Testing: Execute Webhook

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

Annotations already indicate that the tool is not read-only, not destructive, and not idempotent. The description adds only 'trigger a test execution,' which is implied by the name. No additional behavioral traits like side effects, return values, or error conditions are disclosed, but for a simple action, the combination is adequate.

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: one sentence plus a toolset header and parameter list. It is front-loaded with the key action and efficient for a simple tool, though it could benefit from a bit more context.

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?

The description does not explain what a 'test execution' entails, whether it is asynchronous or returns a status, or how to differentiate from similar tools. With no output schema, the agent lacks guidance on what to expect after triggering.

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 parameter 'webhookId' is described in the schema as 'UUID of the webhook,' and the description merely repeats that. Since schema coverage is 100%, the description adds no additional meaning beyond what the schema already provides.

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 action as 'Trigger a test execution of a specific webhook,' with a specific verb and resource. It names the required parameter. However, it does not differentiate from a sibling tool 'contract-testing_test_execute_webhooks' (plural), which may have a similar 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?

No guidelines are provided about when to use this tool versus alternatives, such as the sibling tool for executing multiple webhooks or other webhook actions. No context or prerequisites are mentioned.

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