Get books in a series

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

No annotations are provided, so the description carries the full behavioral burden. It discloses pagination, series ordering, and that each item includes series index and EPUB flag. However, it does not explicitly state read-only semantics, error behaviors, or the full response structure beyond item fields. This is moderate behavioral disclosure.

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, information-dense sentence that front-loads the action and resource. It includes essential context (seriesId source, ordering, pagination, included fields) with zero redundancy or 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 simple list tool, the description is fairly complete: it states input source, ordering, pagination, and key item fields. Without an output schema, it partially describes the response, but the level of detail is sufficient for a straightforward list endpoint.

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 100%, so the schema already documents all parameters with defaults. The description adds value by indicating that seriesId comes from list_series, which helps correct usage. It does not elaborate on page/size beyond the schema, so it stays at baseline.

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 a specific verb and resource: 'List the books in one series by seriesId'. It clearly defines the scope as a single series and notes that items include series index and EPUB availability. It also references 'from list_series', which distinguishes it from sibling tools like list_series itself.

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 a clear workflow: first get seriesId from list_series, then use this tool to list books in that series. It does not explicitly name alternatives or exclusions, but the context is unambiguous and the reference to list_series provides enough guidance.

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