Contract Testing: Execute Webhook

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

The description says 'Trigger a test execution,' which implies an action with potential side effects, contradicting the annotation 'readOnlyHint: true.' No additional behavioral context is provided, such as idempotency or result handling.

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 short and front-loaded with the main purpose. The 'Toolset: Webhooks' line is redundant but does not detract significantly. Overall, it is concise with minimal waste.

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 one-parameter tool with annotations, the description lacks context about the test execution result, whether it is synchronous, and what the return value might be. No output schema exists, so more detail would help completeness.

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 description lists the parameter 'webhookId' with the same description as the input schema. Since schema coverage is 100%, the description adds no new 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 verb 'Trigger a test execution' and the resource 'webhook', distinguishing it from sibling tools like create, delete, update, get, and list webhooks. The purpose is specific and unambiguous.

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 guidance is provided on when to use this tool versus alternatives, such as when to execute a webhook compared to creating or updating one. There are no preconditions or exclusions mentioned.

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