books_get_estimates

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 implies a read-only 'get' operation, but does not disclose pagination behavior, filtering capabilities, response format, or any side effects. The description is too thin to cover what a user might expect from a tool with 8 parameters.

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 short sentence, which is technically concise, but it is under-specified. It lacks structure to organize the large parameter space or to set expectations, so while there is no waste, there is also insufficient substance.

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?

With 8 parameters, no output schema, and no annotations, the description is far from complete. It does not explain how 'all estimates' relates to pagination and filters, nor what the return structure looks like. A minimally viable description for this complexity would at least mention key filtering and pagination options.

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 input schema has 8 parameters with 0% coverage in the description. The description provides no meaning for page, status, per_page, filter_by, sort_order, customer_id, search_text, or sort_column. The schema field names hint at some semantics, but the description adds no value.

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 identifies the action ('Get') and the resource ('all estimates from Books'). It differentiates from sibling tools like books_get_invoices or books_get_customers, though it could be more specific about the scope (e.g., whether 'all' implies no filters).

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 vs alternatives. There is no mention of exclusions or prerequisites. The description merely states the action without contextualizing selection among the many sibling 'get' tools.

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