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

Annotations already cover the safety profile (readOnlyHint=true, openWorldHint=false), and the description adds a genuinely useful behavioral trait: 'Quoted from the site' signals the content is a static, canned answer rather than live data. It still doesn't describe length or format of the returned text, keeping it short of a 5.

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?

A single front-loaded sentence lists the covered topics in a logical order with no filler, and the 'Quoted from the site' qualifier is efficiently appended. It is slightly list-heavy but every clause carries information.

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, read-only static-content tool with no output schema, the description covers what topics are addressed and the static nature of the source. The only gap is no hint about the shape or size of the returned text, which is minor given the annotations.

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 baseline is 4. The description's enumeration of covered topics is content scoping rather than parameter meaning, but no compensation is required here.

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 enumerates the specific content the tool returns (vetting checks, non-guarantees, directory ordering, costs, dispute outcomes), which distinguishes it from find_pros (which actually finds pros). However, it never states the action explicitly ('returns information about' / 'answers'), leaving the retrieval verb implicit.

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 when-to-use or when-not guidance. Siblings such as how_to_get_a_pro and get_answer are semantically adjacent, and the description offers no routing rule to pick between them, leaving the agent to infer the distinction.

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