test_webhook_destination

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

Goes beyond the destructiveHint annotation by disclosing that this is an external mutating operation, that it records the delivery outcome, and that it returns success=false unless confirm=true (otherwise it is a no-op). This is valuable behavioral context.

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 front-loaded with the core purpose and includes structured Args. Some redundancy exists between the opening 'Requires confirm=true' and the confirm parameter explanation, but overall it is compact and scannable.

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 mutating external operation with no output schema, the description covers the essential context: side effects, confirm guard, success behavior, and how to verify the outcome via a sibling tool. Nothing critical is missing.

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%, so the schema already fully documents both parameters. The description repeats the same meaning without adding significant new parameter-level detail, so the baseline of 3 is appropriate.

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?

States a specific verb and resource: send a synthetic payload to a webhook destination. This clearly distinguishes it from sibling tools like create_webhook_destination, delete_webhook_destination, and list_webhook_deliveries.

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?

Explains the required confirm=true condition and instructs the agent to use list_webhook_deliveries to inspect the result. It gives clear operational context, though it does not explicitly contrast this tool with other webhook-related actions beyond the follow-up inspection step.

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