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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, ensuring the agent knows this is a safe, side-effect-free read. The description adds minimal behavioral context, only clarifying the target is a single known item, with no extra information on return format or error behavior.

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 entire description is a single seven-word sentence, directly front-loaded with the action and subject. There is no wasted wording or filler, making it highly concise.

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?

Despite rich annotations, the description fails to specify what 'details' includes—whether it returns cost, comments, filament data, or other related fields. Without an output schema, the agent cannot predict the return structure, and the presence of overlapping sibling tools like get_queue_item_cost heightens the ambiguity.

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 schema defines a single required integer 'item_id' with no description (0% coverage). The description's phrase 'specific queue item' implies the parameter identifies the item, but it does not explain where the ID comes from or any constraints, offering only marginal value beyond the schema's clear property name.

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?

The description uses a specific verb ('Get') and resource ('details of a specific queue item'), clearly distinguishing this from list_queue, get_next_queue_item, and get_queue_item_cost by focusing on a single, identified queue item. It states the primary action unambiguously.

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 information is provided about when to use this tool versus alternatives such as list_queue or get_next_queue_item. The description only states what it does, not the appropriate context or exclusions, leaving the agent without selection guidance.

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