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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is fully covered. The description adds the shape of returned data, which is useful, but says nothing about ordering, pagination behavior, or result size.

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?

One front-loaded sentence with zero filler. Appropriately sized for a simple list tool, though the brevity comes at the cost of omitting pagination semantics.

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?

Announces the returned fields, which partially compensates for the absent output schema. However, a paginated list tool with 0% schema coverage and no pagination guidance leaves an agent guessing about page size and iteration.

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 both parameters (skip, take) are undocumented in the schema. The description never mentions pagination, so an agent gets no explanation of what these offsets mean or what defaults apply.

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 (list) and resource (account-level webhooks) and previews the returned fields (URLs, triggers, active flag). The 'account-level' qualifier implicitly separates it from list_event_type_webhooks, though it never names that sibling.

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 explicit when-to-use guidance or named alternatives. The 'account-level' scope hint lets an agent infer it is not the event-type webhook lister, but nothing states when to reach for get_webhook or list_event_type_webhooks instead.

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