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

With no annotations, the description carries the full behavioral burden, and it discloses only that the operation is a read returning status/HTTP code/retry count. It is silent on retention window, result limits, pagination behavior, and auth requirements, all of which matter for a delivery-log tool.

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?

A single tight sentence with the resource and the salient return fields front-loaded; nothing is wasted or repeated.

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?

No output schema, no annotations, and 0% param coverage mean the description should explain more. It omits pagination via cursor, the meaning of from_ms, and any limits on how many deliveries are returned, so an agent cannot call it confidently.

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%, so the description must compensate, but it only implies webhook_id via 'for an endpoint'. The cursor and from_ms parameters are never explained, leaving the time-range and pagination semantics undocumented for the agent.

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 (Read) and resource (webhook delivery attempts) scoped to a single endpoint, and names the returned fields (status, HTTP code, retry count). It is clearly distinct from webhook_create and webhook_endpoints_list, though it doesn't explicitly say so.

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 when-to-use context, no prerequisites, and no mention of alternative tools such as webhook_endpoints_list or webhook_create. The debugging/troubleshooting use case is only implied by the field list.

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