preflight_book

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

With no annotations, the description should disclose behavioral traits. It only states the action and optional report saving. It does not reveal whether the tool modifies the book, if it requires the book to be open, or if it performs a read-only check. The parameters hint at report saving but not the tool's side effects.

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 a single sentence that conveys the essential action. It is front-loaded and concise. However, it could be slightly more informative without being verbose, balancing conciseness with completeness.

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 lacks important context: whether the book must be opened first, what the preflight report contains, any dependencies on other actions (e.g., saving the book). Given the tool's moderate complexity and lack of output schema, the description is incomplete for an agent to use correctly.

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%, and parameter descriptions are already clear (bookPath, outputPath, autoOpen). The description adds no extra meaning beyond the schema. For a high-coverage schema, a score of 3 is appropriate.

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 'Preflight a book and optionally save the report' clearly states the action (preflight) and the resource (book). It distinguishes from sibling 'preflight_document' which targets individual documents. However, it does not clarify what preflight entails (e.g., error checking, validation).

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 like 'preflight_document' or 'package_book'. There is no mention of prerequisites (e.g., whether the book must be open) or scenarios where this tool is appropriate.

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