tokportal_test_webhook_endpoint

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

Annotations provide basic safety hints (not read-only, not idempotent, not destructive). The description adds useful behavioral context beyond those hints: the event is signed, it is specifically a webhook.test event, and the tool records the delivery result. This helps the agent understand what happens when invoked, though it does not detail permissions or rate limits.

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 two short sentences and every clause earns its place. It front-loads the core action ('Send a test webhook') and then adds a concise, specific behavioral detail about the signed event and delivery recording. No filler or redundancy.

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 tool is simple with only two parameters, full schema coverage, and annotations that clarify it is a mutating but non-destructive action. The description explains the event type and that the delivery result is recorded, which is adequate for invoking the tool. Since there is no output schema, more detail about the returned delivery result would have been useful, but the current description is sufficient for a low-complexity tool.

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 clear descriptions for both id ('Webhook endpoint ID.') and idempotency_key ('Optional Idempotency-Key header for safe retries.'). The tool description does not add parameter-level meaning beyond referring to 'the endpoint,' but the schema already carries the parameter semantics, so baseline 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?

The description clearly states a specific action: 'Send a test webhook' that 'Sends a signed webhook.test event to the endpoint and records the delivery result.' This distinguishes it from sibling tools like create/delete/retry webhook operations by focusing on testing an existing endpoint with a signed event.

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 usage: you invoke this tool to verify a webhook endpoint by sending a test event and seeing the recorded result. However, it does not explicitly state when to prefer this over alternatives like retry_webhook_delivery or how it fits into the webhook configuration workflow, leaving usage guidance mostly implicit.

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