bookshelf_bulk_update_book

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

Annotations already indicate readOnlyHint=false, so the description's 'WRITE' label adds little. It discloses that the operation modifies the instance but provides no details on scope, reversibility, or required 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 very short and front-loaded, but it omits critical usage information. It is concise in length but not in 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?

For a bulk update operation with an open-ended body parameter, the description lacks essential context about what books are affected, how to specify them, and what the response contains. The output schema exists but the description doesn't explain the operation's behavior.

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 schema has one unparameterized body field with no description, and the description does not explain its structure or expected contents. The 'bulk update' name implies the body contains book updates but gives no specific guidance.

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 identifies the tool as a bulk update editor for books, which clearly distinguishes it from singular update_book and other book operations. However, it uses a noun phrase rather than an explicit verb like 'Updates multiple books', slightly reducing clarity.

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 like bookshelf_update_book or bookshelf_bulk_delete_book. The description only states that it modifies the instance, offering no situational context.

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