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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description adds value beyond that by describing the returned content (summaries, totals, shipment/invoice status) and the page-bounded nature of the read, plus an explicit non-mutation disclaimer. It stops short of stating page-size defaults or result-count/pagination behavior.

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?

Three short sentences, front-loaded with the read scope and immediately followed by filter behavior and the negative guarantee. No filler, and every sentence carries information an agent needs.

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 an eight-parameter, no-output-schema list tool, the description conveys what is returned, how filtering works, and that the operation is read-only. The remaining gaps are pagination mechanics and per-boolean filter meaning, which are minor but non-trivial for correct invocation.

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 0%, so the description must carry the parameter burden. It mentions search, customer_number and generic "status filters," which loosely maps to the four booleans, but says nothing about page/limit bounds, defaults, or what each individual boolean (is_booked, is_shipped, is_cancelled, is_ready_for_shipping) selects.

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 uses a specific verb ("Read") with a precise resource ("sales order summaries, totals and shipment/invoice status") and states the page-bounded scope. It doesn't explicitly name a sibling like rackbeat_get_order for single-order retrieval, so the differentiation is implied rather than stated.

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?

It signals when filters are useful ("Optional search, customer number and status filters are sent to Rackbeat") and rules out mutation intent ("Does not book, cancel or ship orders"). However, it never says when to prefer rackbeat_get_order for a single order or how this differs from rackbeat_customers, leaving routing to inference.

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