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

The annotations already indicate readOnlyHint and destructiveHint, but the description adds no behavioral context beyond the word 'preview'. It does not explain ordering, what 'upcoming' means, whether the default queue is always used, or how the count affects the result.

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 short but not effective: it merely restates the title and provides no front-loaded distinguishing information. Under-specification should not be mistaken for conciseness.

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?

Given the presence of several queue-related sibling tools, this description is too sparse to allow reliable selection and invocation. The output schema exists, but an agent still cannot tell how preview relates to list, get_next, create, or update, or what behavior to expect.

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?

The input schema already documents queue_id and indicates defaults, and the description adds no parameter-level meaning. Since schema coverage is 67% and the count parameter lacks a real description, the tool description would need to compensate, but it does not.

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?

Tautological: description restates name/title.

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?

There is no guidance on when to use this tool versus the many queue-related siblings. The description does not mention alternatives, prerequisites, or a scenario where previewing is preferable to listing or fetching the next slot.

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