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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the agent knows this is a safe, closed-set lookup. The description adds little behavior beyond that: it does not say what happens when no role matches, or what the returned page identifier looks like. With annotations carrying the safety profile, a 3 is appropriate.

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?

One sentence, front-loaded with the input expectation and ending on the return. The embedded examples earn their place by defining the parameter domain; there is no filler.

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 one-parameter mapping tool with no output schema, the description covers what goes in and what comes out adequately. It could note the no-match behavior or the shape of the returned page reference, but nothing essential for correct invocation is missing.

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% and the single parameter is a bare 'who' string, so the description carries the full burden. It fills that gap by specifying the expected value is a role or situation and giving three concrete examples ('SaaS CEO', 'lawyer', 'founder raising a round'), which meaningfully constrains how to populate the parameter.

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: 'return the matching Wise Mango ghostwriting page' given a role or situation. The examples make the intended input domain concrete. It does not explicitly contrast itself with the sibling 'wise_mango_services' or 'book_a_call', so it falls short of full sibling differentiation.

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 implied by the phrasing 'Given a role or situation ... return the matching page', which suggests a lookup/mapping use case. However, there is no statement of when to prefer this over 'wise_mango_services' or 'book_a_call', and no exclusions or prerequisites.

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