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

The description is exceptionally transparent about behavioral details beyond annotations: the fixed 24-hour non-extendable lifetime, single issuance of read/write/worker bearer tokens, secret-sharing guidance, job and payload limits, claim limits, per-IP queue limits, non-execution of jobs, and lack of account/API key requirements. This fully compensates for the sparse annotations.

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 description is front-loaded with the core purpose and then efficiently packs the most decision-relevant constraints, token handling, quotas, and execution semantics. No sentence is filler; each adds operational guidance an agent would need.

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 zero-parameter creation tool with an output schema available, the description is remarkably complete. It covers lifetime, authentication tokens, secrets, rate and size limits, non-execution behavior, and authentication requirements, leaving an agent with enough context to invoke the tool correctly.

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 input schema has zero parameters, so parameter semantics carry little burden. Baseline for zero-parameter tools is 4, and the description appropriately focuses on behavioral and usage context instead of parameter syntax.

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 opens with a specific verb and resource: 'Create a small temporary pull queue for cooperating agents.' It clearly identifies this as a queue-creation tool, distinct in nature from sibling inbox, wake, webhook, and heartbeat tools, and it does so without simply restating the tool name.

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 clear context for when this tool is appropriate: creating a temporary pull queue for cooperating agents. It also states that the server does not execute jobs, helping an agent understand this is not a job-execution tool. It does not explicitly name alternative tools or give direct when-not-to-use guidance, but the context is strong enough.

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