BooksGetBooksSchool

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

Annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false, so the safety profile is covered. The description adds the current-school scope, but it does not disclose the result's completeness, ordering, or response shape beyond what the verb and annotations imply.

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 entire description is one short, front-loaded sentence with no filler. It states the action and scope economically without repeating the tool name.

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 parameters and annotations covering safety/open-world behavior, the description is nearly complete for invoking the tool. It does not spell out the return value shape, but for a parameterless list operation that omission is minor.

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 accepts zero parameters, so there is no parameter interpretation burden. The description's scope (current school) is the only relevant operational input, and it is stated.

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 uses the specific verb 'List' and identifies the resource and scope: books available to the current school. This clearly distinguishes it from the sibling BooksGetBooksPlatform (platform-scoped) and BooksGetBook (a single book).

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 implies the tool is for school-scoped reading materials, and the sibling names hint at alternatives, but there is no explicit when-to-use or when-to-prefer-BooksGetBooksPlatform guidance. The intended usage is understandable but left to inference.

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