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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It adds one useful trait, the $4.99 cost, but does not describe whether the operation is read-only or destructive, what it returns, or whether authorization is required.

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 very short, but it is under-specified rather than appropriately concise. It is a fragment with no front-loaded explanation of what the census does, so brevity comes at the cost of clarity.

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 tool with no output schema and no annotations, the description still does not explain what the census returns, what the intake register is, or why it costs $4.99. It is complete only in the narrowest sense of naming a resource.

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 tool takes zero parameters, and the schema has 100% description coverage. Per the rubric, zero parameters yields a baseline of 4 because there are no parameter semantics to add or compensate for.

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 'Intake register census ($4.99)' is a noun phrase that restates the tool name rather than stating a clear verb and resource. It hints at a census of an intake register and includes a price, but does not distinguish itself from sibling tools like drill, triage, verdict, or verify_label.

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, when not to use it, or what alternative tools it competes with. The description offers no context for selecting it over any sibling.

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