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

Annotations already carry the key traits (destructiveHint=true, idempotentHint=true, readOnlyHint=false), so the bar is lower. But the description adds no behavioral context about what the writes mutate, that all variants require idempotency keys, or that operations are destructive. It neither contradicts annotations nor adds anything 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 short, but this is under-specification rather than disciplined conciseness. 'Closed workflow write capability family from the frozen Brain Scanner policy' is filler vocabulary that conveys no actionable meaning.

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?

This is an extremely complex tool — a 25-variant oneOf union with nested payloads, destructive semantics, and no output schema. A one-sentence pointer to a policy is grossly inadequate; an agent cannot select an operation or construct a valid payload from this 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%, so the description must compensate for explaining the 25 operation variants and their payloads. It explains none of them — no operation names, no payload fields, no semantics. The schema carries the entire burden and the description adds zero value.

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 identifies the tool as a family of closed write capabilities from a frozen policy, which is marginally more than a tautology. However, it never states what the tool actually does, what resources it acts on, or which operations are inside the family — an agent cannot tell what this tool accomplishes from the text.

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 its many siblings that overlap with its operations (queue_report, update_queue_item, cancel_queue_item, etc.). No when/when-not conditions, exclusions, or alternative tool names are given.

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