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

Annotations already show destructiveHint=true and readOnlyHint=false, so the agent knows this is a mutating operation. The description adds no additional behavioral context—nothing about side effects, idempotency, required permissions, or what the mutation does to existing schedules. It does not contradict the annotations, but it also does not go beyond them.

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 short sentence is concise, but it is under-specified to the point of being tautological. It has no useful content beyond repeating the tool title, so the sentence does not actually earn its place in the definition.

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 destructive create operation with 5 parameters, an output schema, and many sibling queue tools, this description is completely inadequate. It omits what name, timezone, profile_id, and slots are used for, how they relate, and what effect creating a queue slot has. The annotations tip off destructiveness, but the description leaves the agent unable to build a correct invocation.

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 80% (4 of 5 params have descriptions), so the schema itself provides most of the meaning. The description adds no parameter detail, but with high schema coverage the baseline of 3 is appropriate. The 'slots' parameter is only marked '(required)', so some ambiguity remains, but the tool description could have compensated for that gap and 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?

No context is provided about when to use this tool versus alternatives such as queue_update_queue_slot or queue_list_queue_slots. The description implies a creation action, but gives no prerequisites, no conditions, and no guidance on choosing this over siblings.

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