bookshelf_list_bookfile

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

The annotation readOnlyHint=true aligns with the 'List' action, so no contradiction. However, the description adds no behavioral context beyond the annotation—it does not mention pagination, default return behavior, or any side effects. The annotation already covers safety, but the description contributes little else.

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 extremely brief—one sentence and a query param list. It is front-loaded and without padding, but so terse that it sacrifices meaningful information, making it closer to under-specification than effective conciseness.

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?

Although an output schema exists, the description is incomplete for a filtering tool with 4 optional parameters and no schema descriptions. There is no explanation of what each filter does or how to use them, so an agent cannot reliably determine the correct invocation.

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 0%, so the description needed to compensate but only provides camelCase names (authorId, bookFileIds) that do not match the schema keys (author_id, book_file_ids). No parameter meanings or allowed values are explained, leaving 'unmapped' ambiguous and the parameters confusing.

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 'List bookfile' with a specific verb and resource. It distinguishes from sibling tools like bookshelf_get_bookfile and bookshelf_delete_bookfile by implying a list operation, though it lacks explicit scope or filtering detail.

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 guidance is provided on when to use this tool versus alternatives such as bookshelf_get_bookfile or other list tools. The description only lists query parameter names without explaining any selection criteria or exclusions.

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