list_prompt_books

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

The verb 'List' implies a read-only operation and 'all configured' indicates an unfiltered scope, but no annotations are present to confirm safety. The description does not disclose return format, ordering, failure behavior, or whether any filtering or pagination applies.

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 a single front-loaded sentence with no filler. Every word contributes to the meaning, making it easy for an agent to parse quickly.

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 parameterless list tool, the description is reasonably complete: it names the resource and the scope. The lack of an output schema and any detail about the returned entries is a minor gap, but the simplicity of the tool makes the missing information less critical.

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 has zero parameters, so there are no parameter semantics to explain. The empty schema and the description align, and no additional parameter-level information is needed.

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 states a specific action and resource: 'List all configured prompt books'. The word 'all' and 'configured' clarify the scope and help distinguish this from sibling tools like list_prompts, which operates on prompts rather than prompt books.

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 action and resource make the general use case clear, but the description gives no explicit guidance about when to choose this tool over alternatives. It does not mention list_prompts or related book-configuration tools, so an agent must infer the intended distinction.

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