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

With no annotations provided, the description carries the full burden and delivers unusually valuable behavior: keys are "shown once" (i.e. unrecoverable later), an X-Queue-Key header is used for operations, and there is a real monetary cost ($0.002 via x402) plus a sandbox-vs-production note. It does not state whether creating a queue is reversible, whether name must be unique, or what auth/owner identity is needed.

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?

Front-loaded with the action and the return values, then options, then transport/cost details. The "By OMENZ" attribution and the parenthetical deployment note are somewhat noisy but still informative; no sentence is fully wasted.

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 4-parameter creation tool with no annotations and no output schema, it covers return shape, key-once semantics, header convention, cost, and environment. The remaining gap is parameter-level meaning for lease_seconds, heartbeat_grace_s, and name.

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 coverage is only 25% (only x_queue_key is documented), so the description must compensate. It explains supervisor_box_id ("Agent PO Box for escalations") but only lists lease_seconds and heartbeat_grace_s as "Options" without meaning, and never mentions the `name` parameter at all.

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?

States a specific verb and resource: "create a work queue for a team of agents," and immediately names the artifacts produced (queue_id, owner_key, worker_key). It is distinguishable from the queue_* lifecycle siblings (enqueue, claim, bid), which operate on an existing queue, though it never names an alternative explicitly.

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?

Usage is only implied: the "team of agents" framing and the key outputs suggest this is the bootstrap step before queue_enqueue/queue_bid/queue_claim, but the description never says when to create a queue or when not to. No prerequisites, no routing guidance to siblings.

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