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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, and openWorldHint=false, so the safety profile is covered externally. The description adds no behavioral context beyond the word "update": it does not state what fields can change, whether omitted fields are preserved, how null values behave, or any permission requirements. It does not contradict the annotations, but it also contributes nothing 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?

The single sentence is technically concise, but it is under-specified rather than efficient. For a tool with four parameters and mutation behavior, one tautological sentence does not earn its place as the only guidance. There is no front-loaded actionable detail beyond restating the obvious.

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?

The tool has four parameters, no output schema, and only minimal annotations. A mutation tool like this needs more context to be invoked confidently, especially to distinguish it from the many other updateQueue* siblings. The description leaves the agent with almost no information beyond the schema and the verb "update".

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 100%, and the schema itself explains name, queue_id, folder_id, and description semantics in detail. Because coverage is high, the baseline of 3 applies even though the description adds no parameter meaning. The description does not compensate for anything because the schema already documents the four parameters thoroughly.

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 is "Update a queue." It restates the tool name and title with no additional specificity, so it functions as a tautology rather than a clarifying purpose statement. It does not distinguish this tool from siblings such as updateQueueLabel, updateQueueJsonSchemaSettings, or updateAutomationQueue.

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?

The description gives no usage guidance at all. It does not say when to use this tool instead of updateQueueLabel, updateQueueJsonSchemaSettings, replaceQueueJsonSchema, or other queue-related mutation tools. No prerequisites, exclusions, or alternative conditions are mentioned.

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