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

Annotations already indicate non-readonly and non-destructive behavior. The description adds that a test event is sent, but does not elaborate on potential side effects, rate limits, authentication requirements, or what happens to the webhook. It provides context beyond annotations but remains thin.

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 sentence, front-loaded with the action and purpose. Every word earns its place, no redundancy or fluff.

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 tool with one parameter and no output schema, the description is sufficiently complete. It explains what it does and the required input. However, it could mention the expected response (e.g., success or error), which would aid the agent.

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%, with the parameter webhookId described as 'The webhook ID to test'. The description adds no additional meaning beyond the schema. Baseline 3 applies because schema already does the work.

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 'send a test event' and the resource 'webhook endpoint', and explains the purpose 'to verify it is configured correctly and receiving events'. This distinguishes it from other webhook related tools like list, get, create, update, delete, and rotate.

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 implies use after setting up a webhook, but does not explicitly state when to use versus alternatives or provide when-not-to-use guidance. It is adequate but could be improved by mentioning 'Use after creating or updating a webhook to verify configuration'.

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