bookshelf_get_book_overview

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

The annotations declare readOnlyHint=true, and the description's 'Fetch' wording is consistent with that. However, the description adds no behavioral context beyond the annotation, such as return shape, error behavior, or permissions.

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 or redundant information. It conveys the essential action and target efficiently.

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 simple single-object retrieval with a minimal schema, output schema, and a read-only annotation, the description provides adequate context. It lacks explicit sibling differentiation, but this does not undermine completeness for the basic fetch operation.

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 input schema has only one required integer 'id', and the description confirms the lookup is by id. Although schema description coverage is 0%, the parameter is self-explanatory and the description's 'by id' is sufficient for this simple case.

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 clearly states the tool fetches a single book overview by id, providing a specific verb and resource. It does not explicitly distinguish itself from sibling tools such as bookshelf_get_book, but the 'overview' qualifier helps differentiate.

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?

No explicit guidance is given about when to use this tool versus alternatives like bookshelf_get_book or bookshelf_list_book. The intended use is only implied by the verb and parameter.

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