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

With no annotations, the description carries full burden for behavioral disclosure. It only states 'arrange pages' without explaining side effects, whether it modifies the input file or creates a new one, whether blank pages are added, or what output format to expect. This significant gap makes the behavior opaque.

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, compact sentence with no unnecessary words. It front-loads the action and uses parenthetical clarification for 'signatures', making it efficient and easy to parse. Every word earns its place, though it sacrifices depth for 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 tool with no output schema and minimal annotations, the description is insufficient. It does not explain the outcome of arranging pages, the naming convention, or how it relates to similar page-layout tools. The user is left guessing about the actual behavior, making the context incomplete for a 2-parameter tool.

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 description coverage is 100%, so both parameters are already documented. The description adds no additional meaning beyond the schema, so the baseline of 3 is appropriate. There is no enrichment of parameter details or format expectations.

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 'Arrange pages for booklet printing (signatures)' uses a specific verb and resource, clearly indicating the tool's function. It conveys a distinct purpose related to page reordering for booklet signatures, but does not explicitly differentiate it from sibling layout tools like nup_pdf or posterize_pdf.

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 implies usage for booklet printing, so an agent can infer when to use it. However, it offers no explicit guidance on when to choose this over alternatives, nor does it state exclusions or prerequisites. It meets the 'implied usage' level but lacks comparative context.

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