books_get_purchase_orders

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

No annotations are provided, so the description carries the full burden. It only states 'Get all purchase orders', omitting important behavior such as pagination (page/per_page parameters), optional filters, result ordering, or that this may return a large dataset.

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 front-loads the primary action without any filler. It is efficiently sized for the clarity it provides.

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 12 parameters and no output schema, this description is grossly incomplete. It fails to explain return format, filtering options, pagination behavior, or differentiate itself from siblings like books_get_purchase_order, leaving the agent with insufficient context.

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 has 12 parameters with 0% description coverage, and the description does not explain any parameter meanings. Terms like 'filter_by', 'search_text', and 'sort_column' are left ambiguous, so an agent cannot determine how to use them effectively.

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?

Description uses a specific verb ('Get') and resource ('all purchase orders') from 'Books', clearly conveying a list operation. The word 'all' distinguishes it from the singular sibling 'books_get_purchase_order', and it is clearly a read operation.

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 given on when to use this tool versus alternatives. There is no mention of scenarios where this listing tool is preferred over the singular purchase order retrieval or other list tools, nor any exclusions or prerequisites.

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