bookshelf_update_books_monitored

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

The description says it sets monitored state, which is a mutation (consistent with readOnlyHint=false), but it does not disclose any side effects, whether the operation is atomic, permissions needed, or what the response contains. The annotations provide little, so this minimal info leaves significant behavioral ambiguity.

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?

Two sentences, directly stating the action and the required structure. No redundant phrases; each clause adds value.

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?

The description covers the basic action and the main parameters, and an output schema exists, but it does not address validation rules, optional fields, or error behavior. Given the schema's openness, more detail on the expected resource structure would be valuable.

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 only defines 'body' as an open object with no property descriptions, so the description's clarification that it requires a BooksMonitoredResource with bookIds and monitored provides essential meaning. However, it does not specify data types (e.g., monitored as boolean, bookIds as array of strings) or whether additional properties are accepted, leaving some ambiguity.

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 ('Set') and resource ('monitored state of books'), and 'in bulk' clearly distinguishes it from single-book update tools like bookshelf_update_book. It also names the body structure, making the purpose unambiguous.

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 use when wanting to change monitored status for multiple books, but it does not explicitly state when to prefer this over alternatives like bookshelf_bulk_update_book or when not to use it. No exclusions or alternative tool names are mentioned.

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