test_webhook

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

With no annotations, the description must carry the behavioral burden, and it does disclose the key trait: an outbound HTTP request is fired immediately. It omits important behavior though — whether a delivery log entry is created, whether it counts against webhook quotas/rate limits, what happens on endpoint failure, and whether the call blocks until a response is received.

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?

Two sentences, action front-loaded, no filler. The purpose sentence comes first and the verification use case second, which is the right ordering.

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 action tool with no output schema and no annotations, the description should say what a successful call returns (e.g. delivered status, HTTP status code, delivery ID) and how failures surface. Without that, an agent calling it cannot interpret the result, which is the main remaining gap.

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 0% and the single parameter 'webhookId' is undocumented in both the schema and the description. The phrasing 'a webhook endpoint' hints that the ID selects the target, but the description adds no format, source (where to obtain it), or validity constraints — and with no webhookId example an agent must guess whether it is a slug, UUID, or numeric ID.

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 test payload to a webhook endpoint') with the immediate-trigger behavior made explicit. It is clearly distinguishable from siblings like get_webhook, create_webhook, and get_webhook_logs, which read or manage rather than dispatch a live test.

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 second sentence implies when to use it (verifying reachability and HMAC verification correctness), which is genuine context. However, it names no alternatives or exclusions — e.g. it doesn't say to use get_webhook_logs to inspect past deliveries, or whether it should be avoided in production — so the agent must infer routing.

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