repaginate_book

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

The description only states the action without disclosing any behavioral traits. It does not mention side effects (e.g., page numbers change, need to save), required permissions, or whether the operation is reversible. Since no annotations are provided, the description must carry this burden, and it fails to do so.

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, concise sentence that directly states the tool's function. It is front-loaded and efficient, but somewhat too brief given the complexity of the operation. It earns its place, but more detail could be added without losing conciseness.

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 is highly incomplete given the complexity of repaginating a book. It does not explain what repagination entails (e.g., global renumbering, handling of sections), does not mention return values or output (no output schema), and lacks any context about usage or behavior. The single parameter does not compensate for the missing details.

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 describes the parameter 'bookPath' as 'Path to the book file', which is clear and has 100% schema description coverage. However, the tool description adds no additional meaning or context about this parameter, so it does not reduce ambiguity. Baseline 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 clearly states the action (repaginate) and the target (all documents in a book), distinguishing it from sibling tools that operate on individual pages or book properties. However, the term 'repaginate' may not be universally understood, and it could be slightly more explicit by mentioning 'renumber pages'.

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 or when to avoid it. There is no mention of prerequisites (e.g., book must be open), no comparison to alternatives like synchronize_book or update_chapter_and_paragraph_numbers, and no conditions for effective use.

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