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

Annotations already declare readOnlyHint=false, destructiveHint=false and idempotentHint=false, so the safety profile is covered. The description adds no behavioral context: it doesn't say whether unspecified fields are preserved (partial vs. full update semantics), what happens to a paused or printed item when other fields change, or whether printer assignments trigger rescheduling.

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 compact sentence with the core purpose front-loaded and a parenthetical list of fields. Nothing is wasted, though the field list is too partial to earn full credit for structure.

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?

With 17 parameters, no output schema, and zero schema-level parameter documentation, this definition is far too thin. An agent can identify the tool but cannot confidently construct a call for any field beyond the handful named in the description.

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% across 17 parameters, so the description carries the full burden. It names only about five field concepts (amount, note, print time, material usage, printer assignments), leaving paused, printed, deadline, infinite, priority, autoprint, log_print, for_groups, for_models, persistent, for_printers, and max_concurrent_printers undocumented in both schema and description.

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 gives a specific verb ('Update') and resource ('queue item') and enumerates several editable fields, so an agent knows the general operation. However, it does nothing to distinguish this from close siblings such as move_queue_item, reorder_queue_item, resubmit_queue_item, or revive_queue_item, which also modify queue items.

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 alternatives, nor any mention of prerequisites such as the item needing to be in a specific state or requiring approval/ownership. The agent must infer everything from the tool name.

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