rename_bookshelf

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the action ('rename') but doesn't cover critical aspects like required permissions, whether the change is reversible, rate limits, or error conditions (e.g., invalid ID or duplicate names). This is a significant gap for a mutation tool.

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 appropriately sized and front-loaded, starting with the core purpose followed by parameter details. It avoids unnecessary fluff, though the 'Args:' section could be integrated more seamlessly into the flow.

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?

Given the tool's complexity (a simple mutation with 2 parameters) and the presence of an output schema, the description is somewhat complete but lacks depth. It covers the basic action and parameters but misses behavioral context and usage guidelines, which are crucial since no annotations are provided.

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 description adds minimal semantics beyond the input schema, which has 0% coverage. It names the parameters ('bookshelf_id' and 'name') and gives basic explanations, but doesn't provide format details (e.g., ID constraints or name length limits). With low schema coverage, this partially compensates but leaves gaps.

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's purpose with a specific verb ('rename') and resource ('bookshelf'), making it immediately understandable. However, it doesn't differentiate this tool from potential alternatives among its siblings, such as whether 'update_reading_goal' might also involve renaming or if 'add_bookshelf' handles similar operations.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an existing bookshelf), exclusions, or how it relates to sibling tools like 'add_bookshelf' or 'update_reading_goal', leaving usage context unclear.

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