get_book_info

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

No annotations provided, so the description carries full burden. It only says 'Get detailed information', implying a read operation but no disclosure of side effects, performance implications, authorization needs, or whether the book must be open. Insufficient for responsible tool selection.

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?

Extremely concise: one sentence. But conciseness should not sacrifice informativeness. While efficient, it borders on under-specification. Could be improved without losing brevity.

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 'get' tool with no output schema, the description should indicate what information is returned (e.g., metadata, content preview). It does not. The agent cannot infer the tool's output or suitability. Incomplete for effective use.

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 coverage is 100% with a single parameter 'bookPath' described as 'Path to the book file'. The tool description adds no additional meaning or context about the parameter, such as accepted formats, examples, or constraints. Baseline of 3 not met due to zero added value.

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?

Clear verb and resource: 'Get detailed information about a book'. It directly states the action and object. However, it does not differentiate from sibling 'get' tools like get_document_info or get_group_info, lacking specificity on what 'detailed information' entails.

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 on when to use this tool versus alternatives. The description does not mention any prerequisites, best-use contexts, or when not to use it. Among many 'get_*' siblings, the agent has no criteria to select this one over others.

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