get_book_detail

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

No annotations exist, so description carries full burden. It implies a read operation ('Get detailed information') but does not explicitly state it is read-only, idempotent, or safe. The listed fields suggest low side effects, but transparency is adequate rather than thorough.

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?

Single sentence, clearly front-loaded with the action ('Get detailed information'), and efficiently lists key data fields without redundancy.

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?

No output schema is provided, so the description must explain return values. It lists title, author, description, cover, and 'other metadata'—helpful but vague. Lacks structure (e.g., nested objects, optional fields) that an agent would need for reliable processing.

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% for the single parameter book_id, so baseline is 3. The description adds no extra meaning beyond 'Book ID' from the schema; it does not specify ID format, source, or alternatives.

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 it gets detailed info for a specific book, listing title, author, description, cover, and other metadata. It effectively distinguishes from siblings like get_book_directory (list) and get_chapter_content (chapter-specific).

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 explicit guidance on when to use versus alternatives (e.g., get_book_directory for listing, search_books for discovery). No prerequisites, context, or exclusions provided.

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