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

The only behavioral claim, 'Read-only,' merely restates the readOnlyHint annotation, adding nothing. The phrase 'the approved four steps' hints at fixed canonical content, which is mildly informative, but nothing about freshness, scope, or limitations is disclosed.

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?

Two very short fragments with no padding, and the content list is front-loaded. It is a sentence fragment rather than a well-formed statement, which slightly hurts readability.

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?

With no output schema and no parameters, the description carries the burden of explaining what comes back; it partially does so by listing the content sections, but never frames this as a retrieval of usage guidance nor mentions the answer's format.

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, so the schema is trivially complete and there is nothing for the description to disambiguate. Baseline 4 applies for a 0-parameter tool.

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 names the content it returns (four steps, serving, effect duration) but never states a verb or explicitly says it retrieves usage instructions; that only comes from the tool name and title. It is distinguishable from siblings like where_to_buy or get_policies only by inference from the noun 'steps/serving/effect'.

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 call this versus alternatives such as about_nwb or ask_nwb, nor any stated prerequisites. The agent must guess that this is the canonical source for usage instructions.

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